However, across Latin America, including in Ecuador's Galápagos Islands, smallholder farms play a critical role in food safety and security. We assessed five basic animal welfare measures (feed and water access, shelter availability and housing systems, animal health management, animal behavior, and timely euthanasia) for poultry, pigs, and cattle on Floreana Island, Galápagos. Utilizing assessment standards from multiple US sources and international standards, we developed a questionnaire and used it to conduct in-depth interviews during 4-5 July 2022 with eight participating producers, representing 75% of animal agriculture on Floreana. While we identified opportunities to enhance competencies in animal health management and timely euthanasia, farms performed well in the other assessed measures. Future work should promote knowledge transfer and in-country capacity building in farm biosecurity, access to veterinary care, antimicrobial resistance surveillance, and euthanasia methods. Efforts to positively impact smallholder farm livelihoods in Galápagos-one of the most biodiverse and protected ecosystems on the planet-will sustainably support human health through the interconnected realms of animal health and welfare, wildlife and environmental health, and food safety and security.}, number={4}, journal={ANIMALS}, author={Rhea, Sarah and Camacho, Blanca E. and Amoriello, Carrisa W. and Correa, Maria and Lewbart, Gregory A. and Cruz, Marilyn and Velez, Alberto and Castillo, Paulina and Pairis-Garcia, Monique}, year={2023}, month={Feb} }

The objectives of this study were to survey the aquatic community regarding the husbandry and veterinary care of GPOs, with a specific focus on anesthetic and euthanasia protocols. A two-part web-based survey was distributed to four aquatic and/or veterinary email listservs. Individuals from fifty-two institutions participated in phase one. Results documented that 40 (78 percent) participating institutions currently house GPOs, with most housing one and nine institutions housing two to three GPOs. The median (range) habitat volume is 5405 (1893-16,465) L, and 78 percent of systems are closed. Of the institutions surveyed, 23 have anesthetized or sedated a GPO for nonterminal procedures, including wound care, biopsies, and hemolymph collection. Reported methods of sedation or anesthesia include magnesium chloride, ethanol, isoflurane, tricaine methanesulfonate (MS-222), magnesium sulfate, benzocaine, and dexmedetomidine. Drugs or methods used for euthanasia include magnesium chloride, ethanol, mechanical decerebration, pentobarbital, isoflurane, MS-222, magnesium sulfate, benzocaine, potassium chloride, dexmedetomidine, and freezing. Reported observed side effects include ineffectiveness or inadequate sedation, inking, prolonged drug effects, and behavior changes. Survey data have the potential to guide the husbandry and veterinary care of GPOs and build the framework for future prospective studies on GPO sedation and anesthesia.}, number={7}, journal={VETERINARY SCIENCES}, author={Kirby, Ashley J. and Balko, Julie A. and Goertz, Caroline E.

Dirofilaria immitis, the parasite responsible for canine heartworm disease, is one such threat, as canine infections on the archipelago have been documented. We used a canine heartworm antigen test kit to analyze the blood from 25 juvenile Galapagos sea lions for D. immitis. Two (8%) sea lions tested positive for D. immitis antigen. Using morphologic and genetic assessments, we evaluated 20 filarial-like worms collected from within the heart of an adult male Galapagos sea lion during a previous routine postmortem examination. The intracardiac worms were morphologically consistent with adult D. immitis, and sequence analysis of targeted PCR amplicons confirmed their identity. This is the first report of D. immitis infection in Galapagos sea lions, which could become a major health problem for these pinnipeds. Further studies are necessary to confirm the level of threat from this parasite; however, widespread adoption of routine heartworm testing, prevention, and treatment in the canine population, and the control of mosquitos, could potentially reduce the disease impact on this endangered pinniped species.}, number={3}, journal={JOURNAL OF WILDLIFE DISEASES}, author={Gregory, Taylor M. and Livingston, Isabella and Hawkins, Eleanor C. and Loyola, Andrea and Cave, Ashley and Vaden, Shelly L. and Deresienski, Diane and Breen, Matthew and Riofrio-Lazo, Marjorie and Lewbart, Gregory A. and et al.}, year={2023}, month={Jul}, pages={487–494} }

Study design Prospective, randomized, blinded crossover study. Animals Adult eastern box turtles, two for drug dose evaluation and a group of six (three male, three female) weighing 432 ± 40 g (mean ± standard deviation) for the main study. Methods Animals were randomly assigned to four brachial plexus blocks with lidocaine at 5, 10 and 20 mg kg–1 or 0.9% saline (treatments LID5, LID10, LID20 and CON, respectively), separated by 1 week. Treatment side was randomized and blocks were performed unilaterally. Baseline observations of mentation, heart rate (HR), respiratory rate (fR), skin temperature and limb response to manipulation or toe pinch were evaluated. Assessments were made every 10 minutes until 1 hour of normal sensory and motor function to the treated thoracic limb, or for a total of 2 hours if no block was evident. Results Motor and sensory blockade was achieved in treatments LID10 and LID20 in one turtle, with a latency of 10 minutes and duration of 50 minutes for both doses. Raising of the ipsilateral lower palpebra occurred with both blocks. Turtles administered lidocaine experienced higher HR compared with CON, and HR decreased over time for all individuals. Mentation and fR were not changed with any lidocaine dose. Conclusions The technique was unreliable in producing brachial plexus motor and sensory blockade at the lidocaine doses evaluated in this study. HR was higher in lidocaine-administered turtles but remained within normal limits for the species. No change in mentation or fR was observed among treatments. Clinical relevance General anesthesia with systemic analgesia is recommended for surgical procedures involving the chelonian thoracic limb.

In the Galapagos (Ecuador), an archipelago composed of more than a hundred islets and islands, the presence of T . gondii can be attributed to human-introduced domestic cats, but little is known about its transmission in wildlife populations. We compared the prevalence of antibodies against T . gondii in sympatric Galapagos wild bird species that differ in diet and contact with oocyst-contaminated soil to determine the relative importance of trophic habits as an exposure factor. Plasma samples were obtained from 163 land birds inhabiting Santa Cruz, one of the cat-inhabited islands, and from 187 seabirds breeding in cat-free surrounding islands (Daphne Major, North Seymour, and South Plaza). These samples were tested for the presence of T . gondii antibodies using the modified agglutination test (MAT ≥ 1:10). All seven species of land birds and 4/6 species of seabirds presented seropositive results. All great frigatebirds ( Fregata minor ) (N = 25) and swallow-tailed gulls ( Creagrus furcatus ) (N = 23) were seronegative. Prevalence ranged from 13% in Nazca boobies ( Sula granti ) to 100% in Galapagos mockingbirds ( Mimus parvulus ). It decreased from occasional carnivores (63.43%) to granivores-insectivores (26.22%), and strict piscivores (14.62%).

This disease has been reported in several animal species including invertebrates, cold-blooded vertebrates, mammals, and humans. Melanized fungi have similar phenotypical features and confirmation requires culture and molecular diagnostics. To exemplify this we present a case of a 333 g adult of unknown age, free-ranging, male Eastern box turtle ( Terrapene carolina carolina ) that was referred to the Turtle Rescue Team at North Carolina State University for evaluation of multilobulated masses occupying the entire left orbit and at the right forelimb on the plantarolateral aspect of the foot. A fine needle aspirate cytologic examination of the mass on the right forelimb revealed large numbers of inflammatory cells and fungal organisms. Histopathology of the skin biopsies from the right forefoot was consistent with phaeohyphomycosis. A course of antifungal medication was started (Fluconazole 21 mg/kg loading dose IV then 5 mg/kg PO SID q 30 days). Due to concern for the patient's quality of life and the lack of a curative treatment plan, humane euthanasia was elected. Gross and histological postmortem examination confirmed the presence of multiple coelomic masses similar in appearance to those observed in the left orbit and right forefoot indicating disseminated phaeohyphomycosis. A swab of the periocular mass was submitted for fungal culture and phenotypic identification. The isolate was later identified as Exophiala equina through a combination of phenotypic characterization and sequencing of the ITS region of the nuclear rDNA. Exophiala is a genus in the family Herpotrichiellaceae, order Chaetothyriales and is considered an opportunistic “black yeast” causing infection in aquatic invertebrates, fish, amphibians, reptiles, and mammals including humans.

Blood (hemolymph) transfusions are a widely used therapeutic tool in other species, but investigation in terrestrial arthropods remains scarce. Study objectives were development and evaluation of a serum transfusion process in the thorny devil stick insect. Twenty-five clinically healthy adult insects (9.9-23.0 g) were enrolled and baseline body weights were collected. Hemolymph collection was not successful in males, thus, all were recipient only (n = 12, MR). Females were divided into donor (n = 4, FD) or donor and recipient (n = 9, FDR) groups. Females were manually restrained and up to 1 mL of hemolymph was collected from the abdominal segment caudal to the proximal hindlimb using an 18 g hypodermic needle and passive collection via gravity. Hemolymph was quantified, centrifuged, and the serum separated. Insects were then injected superficially at the lateral aspect of the abdomen with 0.01 mL/g FD serum (MR), lactated Ringer's solution (LRS) equal to collected hemolymph volume (FD), or a combination of FDR serum and LRS equal to collected hemolymph volume (FDR). Response to stimulation, surface temperature, and righting reflex and mortality were serially assessed for up to 24 h and 7 days, respectively, following injection.

Twenty-four clinically healthy jellyfish were assigned into three groups of eight for trials of 0.3 g/L MS-222 (low concentration [LC]), 0.6 g/L MS-222 (high concentration [HC]), and a saltwater control. The goal was to evaluate the effects of MS-222 administration on moon jellyfish movement and response to stimuli. Movement and response to stimuli were measured via rocking and probe stimulus tests and observations of bell contraction quality and body tone. These tests were performed at baseline and throughout both drug exposure and recovery periods. A threshold drug effect was defined based on systematic scoring criteria. Additionally, elastomer tags were administered to four of eight animals in each MS-222 group to evaluate response to tag placement after drug exposure. Threshold drug effect was achieved in six of eight individuals in the LC group and eight of eight individuals in the HC group. The LC group had median threshold and recovery times of 12.2 and 10.1 min, respectively, while the HC group had median threshold and recovery times of 4.0 and 19.9 min, respectively. The HC group had significantly faster time to threshold drug effect (P < 0.001) and longer recovery times (P= 0.005) than the LC group.

The males have smooth copulatory spicules with a rounded, smooth base. All females were gravid. Molecular analysis confirmed that the parasites were a Raillietiella sp. Based on the COI gene, it was most similar (82.7% identical) to an undescribed Raillietiella species from a Caribbean anole (Anolis cristatellus) found in Florida followed by R. hebitihamata (81%), R. indica (80.7%), and R. orientalis (78.8-80.7%). Based on the 18S rRNA gene sequence (1799 bp), it was most similar (99.3% identical) to two undescribed Raillietiella species followed by R. aegypti from a berber skink (Eumeces schneideri) from Saudia Arabia. Phylogenetically, with both molecular targets, the Raillietiella sp. from the Galápagos tortoise grouped with other Raillietiella spp. and was basal within the group. Currently, the origin of this parasite (native to Galápagos or introduced) and the life cycle are unknown. Because some pentastome species, especially when in aberrant hosts, can be pathogenic, additional studies of parasites in native and introduced reptile and amphibian species in the Galápagos are needed to better understand the risk this parasite poses to Galápagos tortoises.}, journal={VETERINARY PARASITOLOGY- REGIONAL STUDIES AND REPORTS}, author={Swanepoel, Liandrie and Loyola, Andrea and Flowers, James and Lewbart, Gregory A. and Garrett, Kayla B. and Yabsley, Michael J.}, year={2022}, month={Oct} }

Study design Prospective, randomized, blinded cadaveric study. Animals A total of 24 frozen-thawed box turtle cadavers; two turtles identified with shoulder injuries were subsequently excluded from the study. The remaining 22 turtles weighed 397 (190–581) g, median (range). Methods The brachial plexus and regional anatomy were identified by dissection of seven cadavers to determine anatomic landmarks for a perineural injection technique. This technique was tested by randomizing 15 cadavers into one of three groups to be injected bilaterally with one of three volumes (0.1, 0.2 or 0.3 mL) of methylene blue dye 1% aqueous solution. Investigators blinded to the assigned group dissected cadavers 15 minutes after injection and used staining of the four cervical spinal nerves (C5–C8; 25% for each nerve) to record a staining score of the brachial plexus (0–100%). Results Based on descriptions of the anatomy of the brachial plexus, an injection technique was designed. Injections of 0.1 mL methylene blue dye resulted in nine/10 injections with 100% nerve stained, and one/10 injection with 50% (two) nerves stained. All injections of 0.2 or 0.3 mL of methylene blue dye resulted in 100% nerves stained. Conclusions and clinical relevance Perineural injection of the brachial plexus with 0.1, 0.2 or 0.3 mL methylene blue dye was successful in 29/30 injections in box turtle cadavers weighing 190–581 g.

Female boobies had longer wing length than males, as well as lower blood urea nitrogen, creatinine, and white blood cell counts. This could be attributed to sexual dimorphism or differences in foraging and mating strategies between the sexes. The time between capture and blood collection had a significant inverse relationship on plasma sodium, potassium, hemoglobin, anion gaps, and lymphocyte counts, suggesting that blood sampling in Nazca boobies should be done in less than 5 m to avoid the impacts of stress on hematological parameters.

Blood gas values and lactate are routinely evaluated during triage of sea turtles, and lactate clearance is of prognostic significance in cold-stunned individuals. Although increases in blood lactate have been associated with muscle exertion, experimental forced submergence, trawl and pound net capture, and general anesthesia, changes in blood lactate associated with short periods of manual restraint have not been evaluated. Venous blood gas and lactate values were tested in 16 juvenile loggerhead sea turtles (Caretta caretta) before and after manual restraint for a 15-min routine veterinary examination. The agreement of blood lactate values between two point-of care analyzers (i-STAT and Lactate Plus) was also compared. Blood pH and bicarbonate (HCO3-) decreased significantly (P < 0.001), and partial pressure of carbon dioxide (pCO2) increased significantly (P < 0.0001) after 15 min. Lactate increased significantly between time points for both analyzers (P < 0.0001). Linear regression analysis showed excellent correlation for lactate measurements obtained on both analyzers (r = 0.998). The mean difference in lactate concentrations between the analyzers was statistically significant, indicating that the methods cannot be used interchangeably (P < 0.0001). Deming regression and Bland-Altman plots identified a slight negative proportional bias for lactate measurement by the Lactate Plus compared with the i-STAT. These results suggest that clinicians should evaluate blood gas values and lactate at the beginning of health evaluations and interpret serial lactate values in sea turtles with caution, because even short periods of manual restraint can induce lactic acidosis and considerably influence these values.}, number={4}, journal={JOURNAL OF ZOO AND WILDLIFE MEDICINE}, author={Mones, Alissa B. and Gruber, Erika J. and Harms, Craig A. and Lohmann, Catherine M.

Our objective was to determine the pharmacokinetics of a single 0.25 mg/kg intramuscular dose of ketorolac in a population of 16 captive-raised juvenile loggerhead sea turtles (Caretta caretta). A sparse sampling protocol was utilized, and blood samples were collected for 12 hours after administration of ketorolac.

CLINICAL FINDINGS Physical examination revealed a large, firm mass at the level of the stomach in each snake. Radiographic findings were consistent with ingestion of a golf ball (3 snakes) or an artificial egg (1 snake). Signs consistent with prolonged impaction included scale loss, dermal abrasions, and apparent loss of body condition in one snake and regional skin ulceration, dehydration, and generalized muscle atrophy in another. TREATMENT AND OUTCOME Nonsurgical removal of the foreign body was attempted in anesthetized or heavily sedated snakes by external manipulation in the orad direction. A golf ball was removed through the oral cavity without complications in 1 snake. In the other 3 snakes, tension caused by the advancing foreign body resulted in full-thickness skin rupture in the cervical region. The procedure was completed with the use of a balloon catheter to aid foreign body advancement for 1 of the 3 snakes, and the skin defect was closed. The procedure was converted to esophagotomy for the other 2 snakes. Three snakes recovered and were released; 1 died of complications from prolonged impaction and esophageal perforation. CLINICAL RELEVANCE The described nonsurgical techniques for removal of ingested round or ovoid foreign bodies were associated with substantial complications in 3 of 4 treated rat snakes.

Twenty-eight healthy koi were anesthetized via immersion in 500 mg/L of buffered MS-222 for 10–12 min, manually removed to room air, and randomly administered 10 mEq/kg KCl (333 mg/ml) via one of three routes—intracardiac injection (IC) (n = 7), intracoelomic injection (ICe) (n = 7), or topical instillment over the gill filaments bilaterally (T) (n = 7)—or received no treatment (control, C) (n = 7). A Doppler ultrasonic flow detector was placed over the heart, and sounds were assessed continuously from immediately prior to treatment until 5 min posttreatment and every 5 min thereafter until Doppler sound cessation, resumption of operculation, or 30 min. Time to Doppler sound cessation or resumption of operculation was recorded. Doppler sound cessation occurred in 7/7 fish in IC (median 0.08, range 0–2.75 min) and 1/7 fish in T (10 min). In T, ICe, and C, 6/7, 7/7, and 7/7 fish, respectively, maintained Doppler sounds to 30 min. All fish in ICe (7/7) and C (7/7) resumed operculation with median (range) times of 22 (7–30) min and 16 (9–29) min from treatment, respectively. Intracardiac KCl at 10 mEq/kg rapidly ceases Doppler sounds and is a successful technique for euthanasia of anesthetized koi. Intracoelomic and topical KCl at 10 mEq/kg were not effective for euthanasia of koi.}, number={3}, journal={JOURNAL OF ZOO AND WILDLIFE MEDICINE}, author={Louis, Meghan M. and Houck, Emma L. and Lewbart, Gregory A. and Posner, Lysa P. and Balko, Julie A.}, year={2020}, month={Sep}, pages={485–489} }

In recent decades its numbers have been threatened by various anthropogenic factors including habitat loss, vehicular trauma, domestic pet predation, climate change, and collection for both the legal and illegal pet trade. Since 1997 the NC State College of Veterinary Medicine Turtle Rescue Team (NC State TRT) has been treating and rehabilitating EBTs. In some cases, injury or disease result in extremely low packed cell volumes (PCVs). In such cases, and when an appropriate donor is available, a whole blood transfusion is performed. Homologous whole blood transfusions were performed to treat severe anemia in four wild EBTs and one client-owned EBT. The PCV of each patient was measured at between 1% and 3% and the donor PCV's were over 15%. No more than 1% total body weight of blood was removed from each donor. This amounts to approximately 3.0 mL of whole blood from a donor. Prior to the transfusion, a macroagglutination cross-match was performed. Blood was either collected from the jugular vein or postoccipital sinus and administered via these same two routes with the exception of one case which received whole blood via the subcarapacial sinus. All wild turtles survived to release, and the client-owned turtle has survived at least 18 months post transfusion. None of the patients or donors were observed to have any reaction or problem with the procedure. The jugular vein was the preferred route for both blood extraction and transfusion. A one-time homologous whole blood transfusion is likely a safe, emergency intervention to treat severe anemia in the EBT.}, number={C}, journal={JOURNAL OF EXOTIC PET MEDICINE}, author={Louis, Meghan M. and Cerreta, Anthony J. and Griffioen, John A. and Mehalick, Michelle L. and Lewbart, Gregory A. and Petritz, Olivia A.}, year={2020}, month={Oct}, pages={27–33} }

L. laevis is also used in biologic research on embryonic development, providing a novel model species for the study of organogenesis, regeneration, evolution, and biologic scaling. However, little scientific literature details disease processes or histologic lesions in this species. Our objective was to describe spontaneous pathologic lesions in L. laevis to identify disease phenotypes. We performed a retrospective analysis of 14 captive L. laevis frogs (wild-caught and captive-bred), necropsied at the NC State University College of Veterinary Medicine between 2008 and 2018. The majority of frogs exhibited renal changes, including varying combinations of tubular epithelial binucleation, karyomegaly, and cytoplasmic vacuolation; polycystic kidney disease; and renal carcinoma. Many of the renal changes are reminiscent of a condition described in Japanese ( Bufo japonicus ) and Chinese (Bufo raddei) toad hybrids that progresses from tubular epithelial atypia and tubular dilation to polycystic kidney disease to renal carcinoma. A second common finding was variably sized, randomly distributed bile duct clusters (biliary proliferation). Other noteworthy findings included regional or generalized edema, intestinal adenocarcinoma, aspiration pneumonia, and parasitism. This retrospective analysis is the first description of histologic lesions identified in captive L. laevis populations, providing new insight into spontaneous disease processes occurring in this species for use in disease diagnosis and clinical management.}, number={3}, journal={COMPARATIVE MEDICINE}, author={Womble, Mandy A. and Lewbart, Gregory A. and Shive, Heather R.}, year={2020}, month={Jun}, pages={239–247} }

Then, after several months with no additional tumour‐directed therapy, the lesion again regressed. Five years post‐irradiation and with no further treatment, the turtle now remains tumour‐free. This unusual pattern of disease regression, followed by transient growth and then long‐term local tumour control, suggests either a spontaneous remission or a pseudoprogression‐like phenomenon.

However, studies of potential paratenic hosts in the Caribbean have been temporally restricted to only diurnal species of lizards, thereby neglecting a dominant component of the nocturnal reptilian community: geckos. Many gecko species are human commensals with activity periods that overlap temporally with those of domestic cats, making them prime candidates as potential transport hosts for cat parasites. However, no studies have reported geckos as paratenic hosts for felid parasites on any Caribbean island. Here we report the first records of subcutaneous oligacanthorhynchid cystacanths on the Venezuelan Coastal Clawed Gecko (Gonatodes antillensis) based on specimens collected in Curaçao and Bonaire. The cysts were identified as belonging to the genus Oncicola, likely those of Oncicola venezuelensis. This study reports these geckos as a new host record for oligacanthorhynchid cystacanths, as well as Curaçao and Bonaire as new geographic locales for these acanthocephalan parasites. We additionally provide a review of saurian cystacanths, comparing the restricted taxonomic focus of transport hosts in Caribbean islands to the distribution of paratenic squamate hosts both in the Neotropics and globally.

Limited data has been published on the hematological parameters of this species and blood sample stability is a notable limitation of hematologic field studies. A relatively novel technique using 10% neutral buffered formalin preserves heparinized whole blood and maintains blood cell stability beyond one month in striped bass. The objective of this study was to evaluate the differences in hematological parameters between tournament-caught and captive-raised largemouth bass using whole blood preservation with neutral buffered formalin.Two populations of largemouth bass (n = 26 wild; n = 29 captive) underwent coccygeal venipuncture to collect heparinized whole blood for packed cell volume, total solids, and manual differential. Formalin preservation of heparinized whole blood facilitated manual hemocytometer analysis. Results were compared between the populations (tournament-caught, and captive-raised) with Wilcoxon rank sum test, a Hotelling's T2 test, and Bonferroni simultaneous 95% confidence intervals to determine significance.The mean packed cell volume (44.9 ± 5.4%) and total solids (7.2 ± 1.1 g/dL) were significantly higher, while the total leukocyte count (7.08 ± 1.86 × 103/µL) was significantly lower in the wild tournament-caught population of largemouth bass, as compared to the captive-raised counterparts (PCV 34.4 ± 7.2%; TS 5.2 ± 1.0 g/dL; WBC 16.43 ± 8.37 × 103/µL). The wild population demonstrated a significantly distinct leukogram characterized by a neutropenia (24.1 ± 12.7%), lymphocytosis (67.7 ± 13.0%), and monocytopenia (8.3 ± 2.9%), while the erythrocyte and thrombocyte counts were not significantly different between populations.Numerous factors have been demonstrated to influence hematologic parameters in fish including age, size, sex, temperature, environmental oxygen level, population density, and infection. The wild population endured stress during angling capture, live-well hypoxia, transport, and extended air exposures at weigh in, which may have caused a stress leukopenia as well as osmoregulatory dysfunction and subsequent hemoconcentration. Further evaluation of seasonal impact as well as increased sample size is warranted to enhance our understanding of largemouth bass hematology.This study concluded that wild largemouth bass captured via tournament angling have higher packed cell volume and total solids, and lower total leukocyte counts, compared to captive-reared individuals.

Vertical beam dorsoventral and horizontal beam latero-lateral views were of excellent quality to identify gastrointestinal structures. The horizontal beam rostrocaudal view immediately postcontrast administration provided gastric and pyloric identification but had lesser diagnostic use at later time points due to anatomical superimposition.

Contrast media entered the large intestine by 24 h in all turtles, and a pyloro-colic indentation was noted at the proximal descending colon. The large intestinal emptying was highly variable due to the interindividual variability of contrast sequestration within the cecal bulb.

Adult males of this species generally have an impressive red coloration of the iris, a feature commonly used to differentiate them from their brown-eyed female conspecifics. Male EBTs that present often display marked pallor of the eyes, which has accompanied clinical anemia. The aim of this study was to examine the relationship between eye color and packed cell volume (PCV) in adult male EBTs, and to assess the accuracy of using eye color to predict PCV. Eye-color scoring cards were created using Adobe Creative Cloud Photoshop®. Each card was composed of blocks displaying progressively lighter tints of a red hue, with a number (score) assigned to each block. Five-block, six-block, and nine-block scoring cards were prepared, with lower numbers (scores) corresponding to lighter hues. To determine the variation in subjective color scores assigned by different human observers, 85 individuals were asked to score EBT eye color in three animals using each of the three scoring cards. Eye color of adult male EBTs that presented to the TRT (n = 18) and those housed at the North Carolina Museum of Natural Sciences (n = 6) were scored using each of the three cards, immediately preceding venipuncture of the occipital sinus for determination of PCV. All animals were scored by at least two individuals. Turtles with low scores (pale eyes) using all three scoring cards consistently had lower PCVs. The five- and six-block scorecards had a positive predictive value (PPV) of 100% while the nine-block score card had a PPV of 71.4%.

The ocular trematode Philophthalmus zalophi was recently reported to affect the survival of juvenile Galapagos sea lions on Santa Cruz Island, resulting in marked ophthalmic changes. This study evaluated the ophthalmic disease and histopathologic effects of P. zalophi on juvenile Galapagos sea lions in the largest rookery located on San Cristóbal Island. Twenty juvenile Galapagos sea lions (10 male and 10 female) were evaluated among five sites in the rookery El Malecón. Ophthalmic examination, including fluorescein staining and evaluation of the adnexa, cornea, and sclera, were performed on each eye. The presence, number, and location of ocular parasites were determined, and parasites were collected for identification. Conjunctival biopsy was performed on 11 animals: 2 that lacked parasites and gross lesions and 9 with both parasites and gross lesions. All parasites collected were confirmed as P. zalophi and identified in 80% (16/20) of the study animals and 70% (28/40) of the examined eyes. Philophthalmus zalophi was most frequently found attached to the nictitating membrane but also located on the palpebral conjunctiva or cornea. The most common clinical signs were varying degrees of conjunctival hyperemia (28/40 eyes), most frequently of the nictitating membrane and mucoid ocular discharge (12/40 eyes). The number of parasites was significantly associated with the degree of conjunctival hyperemia (P < 0.001). Histopathology of conjunctival biopsies revealed organized lymphoid follicles and lymphoplasmacytic infiltrates. The histopathologic changes and gross lesions were likely due to the parasite's attachment to the conjunctiva.

Assessing the health of large, mobile marine animals poses particular challenges, in part because the subjects are difficult to capture and restrain, and in part because standard laboratory and diagnostic tools are difficult to apply in a field setting. Radiography is a critically important diagnostic tool used routinely by veterinarians, but it has seldom been possible to image live marine vertebrates in the field. As a first step toward assessing the feasibility of incorporating radiography into studies of vulnerable species in remote locations, we used portable radiographic equipment to acquire the first digital internal images of living marine iguanas, Amblyrhynchus cristatus, an iconic lizard endemic only to the Galápagos Islands of Ecuador. The radiographic machinery was powered by batteries and performed well on a rocky beach environment of an uninhabited island, despite high heat and humidity. The accuracy of radiographic measurements was validated by computing a snout-vent length (SVL) using bone dimensions and comparing this to standard measurements of SVL made externally with a tape measure. These results demonstrate the feasibility of using radiography to study animals in remote sites, a technique that may prove useful for a variety of physiological, ecological, and biomechanical studies in which reliable measurements of skeletal and soft-tissue dimensions must be acquired under challenging field conditions.

Values affected by temperature were corrected in two ways: (i) with standard formulas and (ii) with auto-corrections made by the portable analyzer. A bench top blood chemistry analyzer was used to measure a series of biochemistry parameters from plasma. Standard laboratory haematology techniques were employed for red and white blood cell counts and to determine haematocrit manually, which was compared to the haematocrit values generated by the portable analyzer. The values reported in this study provide reference data that may be useful in comparisons among populations and in detecting changes in health status among Galápagos sea turtles. The findings might also be helpful in future efforts to demonstrate associations between specific biochemical parameters and disease or environmental disasters.}, journal={CONSERVATION PHYSIOLOGY}, author={Pablo Munoz-Perez, Juan and Lewbart, Gregory A. and Hirschfeld, Maximilian and Alarcon-Ruales, Daniela and Denkinger, Judith and Guillermo Castaneda, Jason and Garcia, Juan and Lohmann, Kenneth J.}, year={2017}, month={May} }

DESIGN Randomized crossover study. ANIMALS 9 healthy yearling loggerhead sea turtles. PROCEDURES Animals received each of 3 doses of alfaxalone (3 mg/kg [1.4 mg/lb], 5 mg/kg [2.3 mg/lb], or 10 mg/kg [4.5 mg/lb]) administered IV in randomly assigned order, with a minimum 7-day washout period between doses. Endotracheal intubation was attempted following anesthetic induction, and heart rate, sedation depth, cloacal temperature, and respirations were monitored. Times to first effect, induction, first voluntary muscle movement, first respiration, and recovery were recorded. Venous blood gas analysis was performed at 0 and 30 minutes. Assisted ventilation was performed if apnea persisted 30 minutes following induction. RESULTS Median anesthetic induction time for all 3 doses was 2 minutes. Endotracheal intubation was accomplished in all turtles following induction. Heart rate significantly increased after the 3- and 5-mg/kg doses were administered. Median intervals from alfaxalone administration to first spontaneous respiration were 16, 22, and 54 minutes for the 3-, 5-, and 10-mg/kg doses, respectively, and median intervals to recovery were 28, 46, and 90 minutes, respectively. Assisted ventilation was required for 1 turtle after receiving the 5-mg/kg dose and for 5 turtles after receiving the 10-mg/kg dose. The 10-mg/kg dose resulted in respiratory acidosis and marked hypoxemia at 30 minutes. CONCLUSIONS AND CLINICAL RELEVANCE IV alfaxalone administration to loggerhead sea turtles resulted in a rapid anesthetic induction and dose-dependent duration of sedation. Assisted ventilation is recommended if the 10 mg/kg dose is administered.}, number={8}, journal={Journal of the American Veterinary Medical Association}, publisher={American Veterinary Medical Association (AVMA)}, author={Phillips, Brianne E. and Posner, Lysa P. and Lewbart, Gregory A. and Christiansen, Emily F. and Harms, Craig A.}, year={2017}, month={Apr}, pages={909–917} }

This study establishes blood chemistry and hematological baseline parameters for the pinfish Lagodon rhomboides, a small marine teleost that is among the most dominant members of near-shore estuarine communities of the Atlantic Ocean and Gulf of Mexico. Given their prominence, pinfishes are an ideal candidate species to use as a model for monitoring changes across a wide range of near-shore marine communities. However, pinfishes exhibit substantial morphological differences associated with a preference for feeding in primarily sea-grass or sand dominated habitats, suggesting that differences in the foraging ecology of individuals could confound health assessments. Here we collect baseline data on the blood physiology of pinfish while assessing the relationship between blood parameters and measured aspects of feeding morphology using data collected from 37 individual fish. Our findings provide new baseline health data for this important near shore fish species and find no evidence for a strong linkage between blood physiology and either sex or measured aspects of feeding morphology. Comparing our hematological and biochemical data to published results from other marine teleost species suggests that analyses of trends in blood value variation correlated with major evolutionary transitions in ecology will shed new light on the physiological changes that underlie the successful diversification of fishes.}, journal={PEERJ}, author={Collins, Sara and Dornburg, Alex and Flores, Joseph M. and Dombrowski, Daniel S. and Lewbart, Gregory A.}, year={2016}, month={Aug} }

This study evaluated the pharmacokinetics of enrofloxacin and its active metabolite ciprofloxacin in the green sea urchin (Strongylocentrotus droebachiensis) after intracoelomic injection and medicated bath immersion administration. The utility of a population pharmacokinetic method using nonlinear mixed effects modeling (NLME) was also evaluated. Thirty sea urchins were assigned to either the injection or immersion group. Twelve study animals and three untreated controls were utilized for each administration method: enrofloxacin 10 mg/kg intracoelomic injection or a 6-hr enrofloxacin 10 mg/L immersion. Each animal was sampled four times from 0 to 120 hr. Water samples were collected during immersion treatment and posttreatment time points in both groups.

Sea urchins play a major role in ocean ecology, echinoculture, and biomedical research. Additionally, sea urchins are commonly displayed in public aquaria. Baseline parameters were developed in unanesthetized urchins for righting reflex (time to regain oral recumbency) and spine response time to tactile stimulus. Tricaine methanesulfonate (MS-222) was used to sedate and anesthetize purple-spined sea urchins and assess sedation and anesthetic parameters, including adhesion to and release from a vertical surface, times to loss of response to tactile stimulus and recovery of righting reflex, and qualitative observations of induction of spawning and position of spines and pseudopodia. Sedation and anesthetic parameters were evaluated in 11 individuals in three circumstances: unaltered aquarium water for baseline behaviors, 0.4 g/L MS-222, and 0.8 g/L MS-222. Induction was defined as the release from a vertical surface with the loss of righting reflex, sedation as loss of righting reflex with retained tactile spine response, anesthesia as loss of righting reflex and loss of tactile spine response, and recovery as voluntary return to oral recumbency. MS-222 proved to be an effective sedative and anesthetic for the purple-spined sea urchin at 0.4 and 0.8 g/L, respectively. Sodium bicarbonate used to buffer MS-222 had no measurable sedative effects when used alone. Anesthesia was quickly reversed with transfer of each individual to anesthesia-free seawater, and no anesthetic-related mortality occurred. The parameters assessed in this study provide a baseline for sea urchin anesthesia and may provide helpful comparisons to similar species and populations that are in need of anesthesia for surgical procedures or research.}, number={4}, journal={Journal of Zoo and Wildlife Medicine}, publisher={American Association of Zoo Veterinarians}, author={Applegate, Jeffrey R., Jr. and Dombrowski, Daniel S. and Christian, Larry Shane and Bayer, Meredith P. and Harms, Craig A. and Lewbart, Gregory A.}, year={2016}, month={Dec}, pages={1025–1033} }

We analysed blood samples drawn from 35 marine iguanas captured at three locations on San Cristóbal Island. A portable blood analyser (iSTAT) was used to obtain near-immediate field results for pH, lactate, partial pressure of O2, partial pressure of CO2, bicarbonate (HCO3 (-)), percentage O2 saturation, haematocrit, haemoglobin, sodium, potassium, ionized calcium and glucose. Parameter values affected by temperature were auto-corrected by the iSTAT. Standard laboratory haematology techniques were employed for differential white blood cell counts and haematocrit determination; resulting values were also compared with the haematocrit values generated by the iSTAT. Body temperature, heart rate, respiratory rate and body measurements were also recorded. Body length was positively correlated with several blood chemistry values (HCO3 (-) and glucose) and two haematology parameters (haemoglobin and manually determined haematocrit). A notable finding was the unusually high blood sodium level; the mean value of 178 mg/dl is among the highest known for any reptile. This value is likely to be a conservative estimate because some samples exceeded the maximal value the iSTAT can detect. For haematocrit determination, the iSTAT blood analyser yielded results significantly lower than those obtained with high-speed centrifugation. The values reported in this study provide baseline data that may be useful in comparisons among populations and in detecting changes in health status among marine iguanas affected by natural disturbances or anthropogenic threats. The findings might also be helpful in future efforts to demonstrate associations between specific biochemical parameters and disease.}, journal={CONSERVATION PHYSIOLOGY}, author={Lewbart, Gregory A. and Hirschfeld, Maximilian and Brothers, J.

These adaptations include a uricotelic nitrogen metabolism and unique cutaneous lipid excretions to prevent evaporative water loss. Uroliths are a rare finding in amphibians. Six adult, presumed wild-caught waxy monkey frogs housed in a museum animal collection were diagnosed with cystic urolithiasis over a 7-yr period, and a single animal was diagnosed with four recurrent cases. Six cases were identified incidentally at routine physical or postmortem examination and four cases were identified during veterinary evaluation for coelomic distension, lethargy, anorexia, and increased soaking behavior. Calculi were surgically removed from three frogs via cystotomy, and a single frog underwent three cystotomies and two cloacotomies for recurrent urolithiasis. Two frogs died within the 24-hr postoperative period. Two representative calculi from a single frog were submitted for component analysis and found to consist of 100% ammonium urate. In the present report, cystic calculi are proposed to be the result of a high-protein diet based on a single invertebrate source, coupled with uricotelism, dehydration, increased cutaneous water loss, body temperature fluctuations facilitating supersaturation of urine, and subsequent accumulation and precipitation of urogenous wastes within the urinary bladder. Surgical cystotomy represents a short-term treatment strategy for this condition. Preventative measures, such as supplying a diversified and balanced diet in addition to environmental manipulation aimed at promoting adequate hydration, are anticipated to be more-rewarding management tools for cystic urolithiasis in the waxy monkey frog.}, number={1}, journal={JOURNAL OF ZOO AND WILDLIFE MEDICINE}, author={Archibald, Kate E. and Minter, Larry J. and Dombrowski, Daniel S. and Jodi L.

Animals were monitored closely and evaluated microscopically after exposure to Melafix according to the label directions for a period of 28 days. Water-quality parameters were monitored on a daily basis. The use of Melafix on goldfish and clownfish appears to be safe as no adverse effects were noted during the experimental period. The results also showed that Melafix has no effect on the water-quality parameters tested. In vitro efficacy studies were conducted by determining the minimum inhibitory concentration and minimum bactericidal concentration of Melafix on various pathogens.

Before performing clinical procedures it is necessary to learn the basic techniques in the laboratory. Objective To assess an animal model, thereby circumventing the following issues: ethical rules, cost, anesthesia and training time. Methods Between July 2012 and September 2012, 182 earthworms were used for 150 microsurgical trainings to simulate discrepancy microanastomoses. Training was undertaken over 10 weekly periods. Each training session included 15 simulations of microanastomoses performed using the Harashina technique (earthworm diameters >1.5 mm [n=5], between 1.0 mm and 1.5 mm [n=5], and <1.0 mm [n=5]). The technique is presented and documented. A linear model with main variable as the number of the week (as a numeric covariate) and the size of the animal (as a factor) was used to determine the trend in time of anastomosis over subsequent weeks as well as differences between the different size groups. Results The linear model showed a significant trend (P<0.001) in time of anastomosis in the course of the training, as well as significant differences (P<0.001) between the groups of animal of different sizes. For diameter >1.5 mm, mean anastomosis time decreased from 19.6±1.9 min to 12.6±0.7 min between the first and last week of training. For training involving smaller diameters, the results showed a reduction in execution time of 36.1% (P<0.01) (diameter between 1.0 mm and 1.5 mm) and 40.6% (P<0.01) (diameter <1.0 mm) between the first and last weeks. The study demonstrates an improvement in the dexterity and speed of nodes' execution. Conclusion The earthworm appears to be a reliable experimental model for microsurgical training of discrepancy microanastomoses. Its numerous advantages, as discussed in the present report, show that this model of training will significantly grow and develop in the near future.}, number={1}, journal={PLASTIC SURGERY}, author={Leclere, Franck Marie P. and Kolb, Frederic and Lewbart, Gregory A. and Casoli, Vincent and Vogelin, Esther}, year={2014}, pages={30–33} }

Alfaxalone is a neurosteroid that acts at the GABAA receptors. Alfaxalone has been evaluated and was deemed successful as an immersion agent in koi carp. Alfaxalone is an effective intramuscular anesthetic in multiple species. A reliable intramuscular anesthetic in fish would be useful in multiple settings. The purpose of this study was to investigate alfaxalone as an intramuscular injectable anesthetic agent in koi carp (Cyprinus carpio). Eight koi carp were utilized in a crossover design. In each trial, six fish received 1 mg/kg, 5 mg/kg, or 10 mg/kg of alfaxalone intramuscularly. They were assessed every 15 min for opercular rate and sedation score. The sedation score was based on a visual scale from 0 to 5, 0 indicating no response and 5 indicating absent righting reflex and anesthesia. Anesthetized koi were placed on a fish anesthesia delivery system (FADS). Time to anesthesia/recovery was recorded and heart rate was recorded every 15 min. Anesthesia was achieved in 0/6, 1/6, and 5/6 fish at 1, 5, and 10 mg/kg, respectively. Duration of anesthesia for one fish at 5 mg/kg was 2 hr. At 10 mg/kg, median anesthesia duration was 6.5 (3–10) hr. At 10 mg/kg, prolonged apnea (2–3 hr) was observed in 3/6 fish, 2/3 died under anesthesia, and 1/3 recovered 10 hr post-injection. Median peak sedation scores were 1.5, 2.5, and 5, at 1, 5, and 10 mg/kg, respectively. A dosage of 10 mg/kg alfaxalone resulted in 33% mortality. The duration of anesthesia and opercular rate were unpredictable.

We compared the onset, duration of anesthesia, and recovery time with both gases, and made observations regarding the effects of the anesthetic protocols. Subjectively, episodes for the isoflurane animals were uneventful. The spiders were calm throughout and did not respond adversely to gas exposure. Conversely, animals anesthetized with carbon dioxide experienced violent inductions and recoveries; the tarantulas appeared agitated when the carbon dioxide flow began. Seizure-like activity and defecation would frequently be noted prior to induction with carbon dioxide. Neither isoflurane nor carbon dioxide seemed to have any clinically apparent short- or long-term impact. The animals were all normal for at least 1-year postexperiment. Future studies should focus on defining the impact, if any, that these anesthetic agents have on the health of invertebrate species.

Thirty (male, n = 27; female, n = 3) blue crabs were randomly assigned to one of four treatment groups of alfaxalone: eight animals were assigned to each of the 5-, 10-, and 15-mg/kg treatment groups, and the remaining six animals were assigned to the 100-mg/kg group. Times for anesthetic induction and recovery periods were recorded. Righting reflex, defensive posturing, and heart rate were evaluated before, during, and after the anesthetic trial. Anesthesia was induced in all 14 animals consolidated into the high-dosage group (15 mg/kg [n = 8] and 100 mg/kg [n = 6]), which was significantly greater than 8 of 16 animals in the low-dosage group (5 mg/kg [n = 2] and 10 mg/kg [n = 6]). Median anesthesia induction time for all crabs was 0.4 min, with no significant difference in induction time between groups observed. Median recovery time was 9.4 min (n = 2), 6.1 min (n = 5), 11.3 min (n = 8), and 66.1 min (n = 5) for the 5-, 10-, 15-, and 100-mg/kg groups, respectively. Recovery times were significantly longer for crabs exposed to an induction dose of 100 mg/kg compared with the 10- and 15-mg/kg induction doses. A significant decrease in the median heart rate was observed between the baseline value and that observed at both induction and 5 min postinjection in the 100-mg/kg dose trial. Two mortalities were observed during the anesthesia trials (n = 1, 10 mg/kg; n = 1, 100 mg/kg), both associated with the autotomization of limbs.

Irrespective of the microsurgical technique that one seeks to integrate or improve, the time commitment in the laboratory is significant. After extensive previous training on several animal models, we sought to identify an animal model that circumvents the following issues: ethical rules, cost, time-consuming and expensive anesthesia, and surgical preparation of tissues required to access vessels before performing the microsurgical training, not to mention that laboratories are closed on weekends.Between January 2012 and April 2012, a total of 91 earthworms were used for 150 microsurgical training exercises to simulate vascular end-to-side microanastomosis. The training sessions were divided into ten periods of 7 days. Each training session included 15 simulations of end-to-side vascular microanastomoses: larger than 1.5 mm (n=5), between 1.0 and 1.5 mm (n=5), and smaller than 1.0 mm (n=5). A linear model with the main variables being the number of weeks (as a numerical covariate) and the size of the animal (as a factor) was used to determine the trend in time of anastomosis over subsequent weeks as well as the differences between the different size groups.The linear model shows a significant trend (p<0.001) in time of anastomosis in the course of the training, as well as significant differences (p<0.001) between the groups of animals of different sizes. For microanastomoses larger than 1.5 mm, the mean anastomosis time decreased from 19.3±1.0 to 11.1±0.4 min between the first and last week of training (decrease of 42.5%). For training with smaller diameters, the results showed a decrease in execution time of 43.2% (diameter between 1.0 and 1.5 mm) and 40.9% (diameter<1.0 mm) between the first and last periods. The study demonstrates an improvement in the dexterity and speed of nodes execution.The earthworm appears to be a reliable experimental model for microsurgical training of end-to-side microanastomoses.

This expertise is necessary for liver research, microsurgical reconstruction of the esophagus by free jejunum or reconstruction of the hepatic artery during reimplantation from living donors. The goal of this prospective study is to assess the reliability of an invertebrate model for microsurgical training. Between November 2011 and January 2012, 150 microsurgical trainings simulating vascular end-to-end microanastomoses were performed on 134 earthworms.

Amphibians and reptiles have a preferred optimal temperature zone that allows for optimal biological function. Physiologic processes in ectotherms are influenced by temperature; these animals have capabilities in which they make use of behavioral and physiologic mechanisms to thermoregulate. Core body, ambient air, body surface, and surface/water temperatures were obtained from six ectothermic species including one anuran, two snakes, two turtles, and one alligator. Clinically significant differences between core body temperature and ambient temperature were noted in the black rat snake, corn snake, and eastern box turtle. No significant differences were found between core body and ambient temperature for the American alligator, bullfrog, mata mata turtle, dead spotted turtle, or dead mole king snake. This study indicates some ectotherms are able to regulate their body temperatures independent of their environment. Body temperature of ectotherms is an important component that clinicians should consider when selecting and providing therapeutic care.

Analgesia is a controversial and often neglected topic with invertebrates because of the common belief that invertebrates do not feel pain.

Five eastern box turtles, Terrapene carolina carolina, that either died or were euthanatized due to disease or injuries were used for this work. Tissues were obtained from the five turtles. Western blot analysis was used to evaluate tissues for COX-1 and COX-2 proteins. Densiometric analysis was used to compare Western blot bands within each turtle. COX-1 and COX-2 were found in the liver, kidney, grossly normal muscle, and grossly traumatized (inflamed) muscle of all study turtles. In all cases, COX-1 and COX-2 proteins were increased in traumatized muscle over grossly normal nontraumatized muscle. The highest levels of COX-1 and COX-2 proteins were found in kidney and liver. There was no statistical difference between the amount of COX-1 protein in liver and kidney, but traumatized muscle compared with grossly normal muscle had significantly greater COX-1 but not COX 2 protein concentrations. There was no statistical difference between the amount of COX-2 protein in liver and kidney. Traumatized muscle expressed nonstatistically significant greater amounts of COX-2 compared with grossly normal muscle. COX-1 and COX-2 proteins are expressed in turtle tissues, and both isoforms are upregulated during inflammation of muscle tissue. Traditional nonsteroidal anti-inflammatory drugs (NSAIDs) that block both COX isoforms might be more efficacious than COX-2-selective drugs.

NSAIDs are known to act by providing anti-inflammatory and analgesic actions by inhibiting the synthesis of prostaglandin E2 (PGE2). The objective of this study was to evaluate whether the intramuscular administration of meloxicam would decrease the circulating serum PGE2 levels in the North American bullfrog (Rana catesbeiana) following tissue trauma induced by a punch biopsy. Eighteen adult North American bullfrogs were randomly assigned to two treatment groups: meloxicam (0.1 mg/kg i.m.) and control (0.9% saline i.m.). Blood was obtained via cardiocentesis immediately prior to administration of the two treatment regimes and serum was frozen. A 4-mm punch biopsy was taken from the right triceps femoris muscle to induce an inflammatory response. Twenty-four hours later, a second blood sample was collected and serum was harvested and frozen. Serum PGE2 concentrations were measured using a commercial PGE2 enzyme assay (EIA) kit. Twenty-four hours following the biopsy, the mean circulating PGE2 levels of animals treated with meloxicam was 57.79 ± 12.35 pg/ml, which did not differ significantly from animals that were treated with saline (85.63 ± 17.55 pg/ml, P ≥ 0.05). The calculated means of the absolute change between the circulating baseline PGE2 levels and the postinjury circulating PGE2 levels were significantly lower in animals treated with meloxicam (13.11 ± 17.31 pg/ml) than in control animals treated with saline (46.14 ± 38.02 pg/ml) (P ≤ 0.05). These results suggest that the systemic administration of meloxicam at a dosage of 0.1 mg/kg once daily suppresses circulating serum PGE2 levels postinjury in the North American bullfrog.}, number={4}, journal={JOURNAL OF ZOO AND WILDLIFE MEDICINE}, author={Minter, Larry J. and Clarke, Elsburgh O. and Gjeltema, Jenessa L. and Archibald, Kate E. and Posner, Lysa P. and Lewbart, Gregory A.}, year={2011}, month={Dec}, pages={680–685} }

Animals —123 jellyfish (44 with eversion syndrome and 79 without) at 6 institutions. Procedures —Elemental analyses were performed on 24 jellyfish with eversion syndrome and 49 without, and histologic examinations were performed on 20 jellyfish with eversion syndrome and 30 without. A questionnaire distributed to 39 institutions with Scyphomedusa jellyfish was used to gather information about husbandry, environmental conditions, and prevalence of eversion syndrome. Results —For the 39 institutions that responded to the questionnaire, prevalence of eversion syndrome ranged from 0% to 30%. For Aurelia aurita , eversion was more common at institutions with only captive-raised and no wild-caught jellyfish. Eversion was most common among young (approx 1- to 2-month-old) growing jellyfish and older (> 6-month-old) jellyfish. Elemental analysis revealed only minor differences between affected and unaffected jellyfish, with great variation among jellyfish from the same institution and among jellyfish from different institutions. Striated muscle degeneration and necrosis and extracellular matrix (mesoglea) degeneration were evident on histologic examination of affected jellyfish. Conclusions and Clinical Relevance —Results suggested that eversion syndrome is a complex phenomenon associated with degenerative changes of the bell matrix.}, number={9}, journal={American Journal of Veterinary Research}, author={Freeman, K.S. and Lewbart, G.A. and Robarge, W.P. and Harms, C.A. and Law, J.M. and Stoskopf, M.K.}, year={2009}, month={Sep}, pages={1087–1093} }

Clinical Findings —A fracture of the left femur was suspected on examination and palpation of the hind limbs, but no other injuries or abnormalities were detected. While the bullfrog was sedated, whole-body radiographic views were obtained, which revealed a closed midshaft comminuted fracture of the left femur. Treatment and Outcome —The fracture was repaired by use of an internal fixation technique that included Kirschner wires, a positive-profile pin secured along the femur with encircling sutures, and polymethylmethacrylate molded around the entire apparatus. There were no major complications during the postoperative rehabilitation period. One year after surgery, radiography revealed complete fracture healing and the bullfrog was released back into the wild. Clinical Relevance —Presently, there are no widely accepted methods for fracture fixation in amphibians. Factors associated with their aquatic environment and lengthy fracture healing time must be addressed when planning fracture fixation strategies. In the bullfrog of this report, the applied internal fixation method provided effective long-term stabilization of the femur, allowed for normal movement, and enabled the bullfrog to be housed in an aquatic environment immediately after surgery.}, number={8}, journal={JAVMA-JOURNAL OF THE AMERICAN VETERINARY MEDICAL ASSOCIATION}, author={Royal, Lillian W. and Grafinger, Michael S. and Lascelles, B.

Phylogenetic analysis based on P gene sequences revealed 2 distinct subgroups within SVCV genogroup Ia, designated SVCV Iai and Iaii, and suggests at least 2 independent introductions of the virus into the USA in 2002. Combined P- and G-sequence data support the emergence of SVCV in Illinois, USA, and in Lake Ontario, Canada, from the initial outbreak in Wisconsin, USA, and demonstrate a close genetic link to viruses isolated during routine import checks on fish brought into the UK from Asia. The data also showed a genetic link between SVCV isolations made in Missouri and Washington, USA, in 2004 and the earlier isolation made in North Carolina, USA, in 2002. However, based on the close relationship to a 2004 UK isolate, the data suggest than the Washington isolate represents a third introduction into the US from a common source, rather than a reemergence from the 2002 isolate. There was strong phylogenetic support for an Asian origin for 9 of 16 UK viruses isolated either from imported fish, or shown to have been in direct contact with fish imported from Asia.

Design —Prospective study. Animals —71 healthy adult koi. Procedures —Plasma was analyzed for concentrations or activities of albumin, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, bile acids, BUN, calcium, cholesterol, creatine kinase, γ-glutamyltransferase, globulin, glucose, K, Na, P, total bilirubin, total protein, and uric acid. Duplicate samples were evaluated by use of the intraclass correlation coefficient to determine reproducibility. To assess the magnitude of differences between replicate samples, the absolute mean difference, SD, and minimum and maximum values were calculated for each analyte. Median values and reference intervals were calculated. Results —Intraclass correlation coefficient values were excellent for all analytes except alanine aminotransferase (good), Na (poor), γ-glutamyltransferase (poor), and P (poor). Reference intervals were established. Conclusions and Clinical Relevance —The in-house tabletop biochemical analyzer had good precision for measuring most plasma biochemical analytes. Further research and comparison with other reference procedures are needed before reference intervals and precision can be established for globulin, Na, P, K, and albumin.

Malathion is one of the most widely used OP pesticides with numerous agricultural and therapeutic applications, and exposure to environmentally applied malathion can lead to adverse systemic effects in anurans. Cutaneous absorption is considered a potentially important route of environmental exposure to OP compounds for amphibians, especially in aquatic environments. One in vitro system commonly used to determine the absorption kinetics of xenobiotics across the skin is the two-compartment Teflon flow-through diffusion cell system. To establish cutaneous absorption kinetics of malathion, six full thickness skin samples taken from both the dorsal and ventral surfaces of each of three bullfrogs (Rana catesbeiana) and three marine toads (Bufo marinus) were placed into two-compartment Teflon flow-through diffusion cells perfused with modified amphibian Ringer's solution. A 26 μg/cm2 dose of malathion-2,3-14C diluted in 100% ethanol was applied to each sample (0.44–0.45 μCi). Perfusate was collected at intervals over a 6 h period and analyzed for 14C in a scintillation counter. At the end of 6 h, surface swabs, tape strips, biopsy punches of the dosed area of skin, and peripheral samples were oxidized and analyzed for residue effects. Malathion absorption was greater across the ventral skin compared to dorsal skin in both bullfrogs and marine toads.}, number={3}, journal={ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY}, author={Willens, Scott and Stoskopf, Michael K. and Baynes, Ronald E. and Lewbart, Gregory A. and Taylor, Sharon K. and Kennedy-Stoskopf, Suzanne}, year={2006}, month={Nov}, pages={255–262} }

A pilot study with two animals was also performed following a 10 mg/kg p.o. administration. The concentration of enrofloxacin in hemolymph was assayed using high-performance liquid chromatography (HPLC) and pharmacokinetic parameters were derived from compartmental methods. In the i.v. study, the terminal half-life (t(1/2)), apparent volume of distribution, and systemic clearance were respectively 1.81 h, 385 mL/kg, and 4.71 mL/min/kg. Following bath administration the t(1/2), peak hemolymph concentration (C(max)), and area under the curve to infinity (AUC(0-infinity)) were 1.01 h, 0.5 +/- 0.12 mug/mL, and 0.98 microg.h/mL, respectively. After oral administration, the t(1/2), C(max), and AUC(0-infinity) were 1.01 h, 10.95 microg/mL, 26.71 mug.h/mL, respectively. The active metabolite of enrofloxacin, ciprofloxacin, was not detected in any samples tested. The hemolymph concentration was still above minimum inhibitory concentration (MIC) values for shrimp and fish bacterial isolates at 6 h after i.v. administration, therefore, a dose of 5 mg/kg i.v. every 8-12 h is suggested for additional studies of efficacy. The C(max) value for the water bath was lower than for the i.v. study, but a bath of 2.5 mg/L for 5 h once to twice daily is suggested for additional studies to test efficacy against highly susceptible organisms. Although only two animals were used for the oral study, a dose of 10 mg/kg produced hemolymph concentrations of enrofloxacin that were in a range consistent with therapeutic efficacy in other species.}, number={5}, journal={JOURNAL OF VETERINARY PHARMACOLOGY AND THERAPEUTICS}, author={Gore, SR and Harms, CA and Kukanich, B and Forsythe, J and Lewbart, GA and Papich, MG}, year={2005}, month={Oct}, pages={433–439} }

Design —Prospective study. Animals —20 healthy koi. Procedure —6 koi were anesthetized with tricaine methanesulfonate, and a 23-gauge, three-fourths-inch butterfly catheter was inserted into the coelomic cavity and secured. Catheters were flushed daily for 6 days with 0.4 mL of sterile saline (0.9% NaCl) solution containing heparin (100 units of heparin in 250 mL of saline solution) without removing koi from the aquarium. At the end of the sixth day (144 hours), each of the 6 catheterized koi and 6 uncatheterized (control) koi was anesthetized individually. Enrofloxacin (10 mg/kg [4.5 mg/lb]) was administered to catheterized koi via the injection port and to control koi via a 23-gauge needle in the same site as the catheter placement. A pharmacokinetics study was performed on multiple plasma samples to validate the efficiency of the catheter. Reliability of the catheterization method was determined in 8 koi. Results —All 6 catheters remained patent and effective for the 6 days prior to the start of the pharmacokinetics study. Results for the 2 routes of administration were comparable, and all koi survived the study without any detectable clinical problems. Conclusions and Clinical Relevance —An intracoelomic catheter was effective and safe when maintained in koi for at least 6 days. This would be highly beneficial for veterinarians, clients, and fish, especially when intracoelomic administration of a drug would require daily or more frequent dosing.

Thirty-eight box turtles were randomized to either barren (flat newspaper substrate) or enriched (cypress mulch substrate, shredded paper and a hide box) enclosures for a 1-month period. Complete blood counts, fecal corticosterone, and body weights were measured at the beginning and end of the test period. Activities performed within the two environments were also compared. Turtles in enriched enclosures had a significantly lower heterophil to lymphocyte ratio (H/L) at the end of the treatment period (p = 0.01). Enriched-housed turtles also spent significantly less time engaged in escape behaviour (p < 0.01). There was no significant difference in fecal corticosterone or body weight change between the two treatment groups. At the beginning of the study, each turtle was placed in a preference test system in which it could move freely between a barren and enriched environment. Relative-dwelling time (RDT) was determined for each environment. Turtles showed a distinct preference for the enriched environment (90.9% median RDT, p < 0.01). After the 1-month housing experiment turtles were revaluated for preference to determine if previous housing experience affected choice. Turtles continued to prefer an enriched environment regardless of prior housing conditions (97.6% median RDT, p < 0.01). Results of this study demonstrate that the captive housing environment impacts the physiology and behaviour of box turtles, and suggest housing modifications that encourage typical species-specific behaviour should be provided.}, number={4}, journal={APPLIED ANIMAL BEHAVIOUR SCIENCE}, author={Case, BC and Lewbart, GA and Doerr, PD}, year={2005}, month={Aug}, pages={353–365} }

The pharmacokinetic properties of the antifungal drug fluconazole, after intravenous (i.v.) and subcutaneous (s.c.) injections, were studied in juvenile loggerhead sea turtles (Caretta caretta) housed at 23.0-26.5 degrees C. Fluconazole pharmacokinetic properties were further assessed in a multiple-dose s.c. regimen derived from the pharmacokinetic parameters determined in the single-dose study. Pharmacokinetic parameters were calculated, using a two-compartment model, from plasma concentration-time data obtained after single i.v. and s.c. administrations of fluconazole at a dosage of 2.5 mg/ kg body weight in six juvenile sea turtles. Blood samples were collected at intervals through 120 hr after each dose, and the concentration of fluconazole in plasma was measured by reverse-phase high-performance liquid chromatography. The i.v. and s.c. elimination half-lives were 139.5 +/- 36.0 and 132.6 +/- 48.7 hr (mean +/- SD), respectively. Systemic clearance of fluconazole was 8.2 +/- 4.3 ml/kg x hr, and the apparent volume of distribution at steady state was 1.38 +/- 0.29 L/kg. A multiple-dose regimen was derived, which consisted of a loading dose of 21 mg/kg body weight and subsequent doses of 10 mg/kg administered through s.c. injection every 120 hr (5 days). This regimen was administered to four juvenile sea turtles for 10 days, and blood samples were taken to determine peak and trough plasma concentrations of fluconazole. The mean concentrations for the two peak concentrations were 16.9 +/- 1.1 and 19.1 +/- 2.8 microg/ml 4 hr after dosing, and the mean concentrations for the three trough concentrations were 7.2 +/- 2.2, 10.4 +/- 2.7, and 10.7 +/- 2.9 microg/ml 120 hr after dosing. The terminal half-life after the last dose was calculated at 143 hr. Throughout the multiple dosing, fluconazole concentrations remained above approximately 8 microg/ml, a concentration targeted when treating mycotic infections in humans.

Stages of anesthesia and recovery were measured, and physiologic data were collected before and during anesthesia.Interval to induction was more rapid and recovery more prolonged in fish exposed to eugenol, compared with those exposed to tricaine methanesulfonate. The margin of safety for eugenol was narrow, because at the highest concentration, most fish required resuscitation. Mixed venous-arterial PO2 consistently decreased with anesthesia, while PCO2 consistently increased with anesthesia in all fish regardless of anesthetic agent. The increase in PCO2 was accompanied by a decrease in pH, presumably secondary to respiratory acidosis. Anesthesia was associated with increased blood glucose, potassium, and sodium concentrations as well as Hct and hemoglobin. Fish anesthetized with eugenol were more likely to react to a hypodermic needle puncture than fish anesthetized with tricaine methanesulfonate.Anesthesia induced with tricaine methanesulfonate or eugenol contributes to hypoxemia, hypercapnia, respiratory acidosis, and hyperglycemia in red pacu. Similar to tricaine methanesulfonate, eugenol appears to be an effective immobilization compound, but eugenol is characterized by more rapid induction, prolonged recovery, and a narrow margin of safety. Care must be taken when using high concentrations of eugenol for induction, because ventilatory failure may occur rapidly.

The 4 h maximum concentration (Cmax) of 1.64 micrograms/ml, following a single 5.0 mg/kg dosing easily exceeds the in vitro minimum inhibitory concentration (MIC) for 20 bacterial organisms known to infect fish. At 48 h post i.m. administration, the mean plasma enrofloxacin concentration was well above the MIC for most gram-negative fish pathogens. The gavage method of oral enrofloxacin administration produced a Cmax of 0.94 microgram/mL at 6-8 h. This Cmax was well above the reported in vitro MIC. A bath immersion concentration of 2.5 mg/L for 5 h was used in this study. The Cmax of 0.17 microgram/mL was noted on the 2 hour post-treatment plasma sample. Plasma concentrations of enrofloxacin exceeded published in vitro MIC's for most fish bacterial pathogens 72 h after treatment was concluded.

This study describes the fine structure of the nuchal and associated glands of Parapionosyllis manca. In each nuchal organ, the epithelium of the nuchal cleft encloses an olfactory chamber through which sensory cilia and microvillus-like processes radiate. These sensory components originate from bulbs of sensory cells that are closely associated to form a sensory bundle. Each bundle of cells is encased in a palisade of support cells bearing motile cilia. Numerous secretory vesicles occur in the cytoplasm of the support cells and beneath the modified cuticle of the nuchal organ. The support cells of the olfactory region extend posteriorly to form the nuchal lobes, or glands. The cells are elongate and taper to a thin neck just before leaving the sensory area of the nuchal organ. There are essentially no nuclei in the sensory region as these and most of the other cellular organelles are concentrated in the lobes that extend into the body cavity but are contained by the epidermal basement matrix. The nuchal organ is innervated by the nuchal nerve, which extends posteriorly from the hind portion of the brain. Additional key words: ultrastructure, sensory organs, Annelida The nuchal of polychaete annelids are a pair of pits located in the head region of the animal, usually between the prostomium and the peristomium. They are believed by most investigators to be chemosensory (Lang 1888; Rolleston & Jackson 1888; Rullier 1950, 1951; Bullock & Horridge 1965; Purschke 1986, 1990; Schlotzer-Schrehardt 1986; Rhode 1989, 1990) and probably function in the location of food. Others believe the may also have a role in coordinating reproductive behavior (Schlotzer-Schrehardt 1987). The present study describes the nuchal of Parapionosyllis manca, an interstitial polychaete belonging to the family Syllidae. The nuchal organ, found in many families of polychaetes with varying lifestyles, was first described in 1849 by J.H. Huxley while on an expedition aboard the H.M.S. Rattlesnake. He collected two specimens of Tomopteris onisciformes (Tomopteridae) and noted the presence of a pair of rounded elevations running back along the dorsal surface in the form of a band or ridge between the narrow neck and the second pair of cephalic appendages. This information was published by Carpenter (1859). A year later, the were more a To whom correspondence should be addressed.

Several decades later workers began to speculate on the function of nuchal organs. Lang (1888) referred to nuchal as of smell.

Intracytoplasmic organisms resembling rickettsia were observed in tissues of two blue-eyed plecostoitius, Panaqae suttoni (Eigenmann & Eigenmann), a tropical freshwater fish. Gross lesions were limited to renomegaly and splenomegaly. Cytopathological and histopathological examination of the various tissues revealed numerous small, discrete, coccoid organisms in the cytoplasm of monocytes as well as tissue macrophages of the spleen, heart, kidney and sometimes liver. Transmission electron microscopy confirmed that these organisms were within membrane-bound vacuoles and had a morphology resembling rickettsia.}, number={2}, journal={JOURNAL OF FISH DISEASES}, author={KHOO, L and DENNIS, PM and LEWBART, GA}, year={1995}, month={Mar}, pages={157–163} }
