Despite frequent collection of bile for culture-based diagnosis of bacterial cholecystitis, it is unknown whether bile from healthy dogs harbors uncultivable bacteria or a core microbiota. The answer to this question is critical to understanding the pathogenesis of biliary infection and as a baseline to exploration of other biliary diseases in dogs where uncultivable bacteria could play a pathogenic role. A pressing example of such a disease would be gallbladder mucocele formation in dogs. This prevalent and deadly condition is characterized by excessive secretion of abnormal mucus by the gallbladder epithelium that can eventually lead to rupture of the gallbladder or obstruction of bile flow. The cause of mucocele formation is unknown as is whether uncultivable, and therefore unrecognized, bacteria play any systematic role in pathogenesis. In this study we applied next-generation 16S rRNA gene sequencing to identify the culture-negative bacterial community of gallbladder bile from healthy dogs and gallbladder mucus from dogs with mucocele formation. Integral to our study was the use of 2 separate DNA isolations on each sample using different extraction methods and sequencing of negative control samples enabling recognition and curation of contaminating sequences. Microbiota findings were validated by simultaneous culture-based identification, cytological examination of bile, and fluorescence in-situ hybridization (FISH) performed on gallbladder mucosa. Using culture-dependent, cytological, FISH, and 16S rRNA sequencing approaches, results of our study do not support existence of a core microbiome in the bile of healthy dogs or gallbladder mucus from dogs with mucocele formation. Our findings further document how contaminating sequences can significantly contribute to the results of sequencing analysis when performed on samples with low bacterial biomass.}, number={2}, journal={PLOS ONE}, author={Gookin, Jody L. and Hartley, Ashley N. and Aicher, Kathleen M. and Mathews, Kyle G. and Cullen, Rachel and Cullen, John M. and Callahan, Benjamin J. and Stowe, Devorah M. and Seiler, Gabriela S. and Jacob, Megan E. and et al.}, year={2023}, month={Feb} } @article{gilbertie_schaer_engiles_seiler_deddens_schubert_jacob_stefanovski_ruthel_hickok_et al._2022, title={A Platelet-Rich Plasma-Derived Biologic Clears Staphylococcus aureus Biofilms While Mitigating Cartilage Degeneration and Joint Inflammation in a Clinically Relevant Large Animal Infectious Arthritis Model}, volume={12}, ISSN={2235-2988}, url={http://dx.doi.org/10.3389/fcimb.2022.895022}, DOI={10.3389/fcimb.2022.895022}, abstractNote={The leading cause of treatment failure in Staphylococcus aureus infections is the development of biofilms. Biofilms are highly tolerant to conventional antibiotics which were developed against planktonic cells. Consequently, there is a lack of antibiofilm agents in the antibiotic development pipeline. To address this problem, we developed a platelet-rich plasma (PRP)-derived biologic, termed BIO-PLY (for the BIOactive fraction of Platelet-rich plasma LYsate) which has potent in vitro bactericidal activity against S. aureus synovial fluid free-floating biofilm aggregates. Additional in vitro studies using equine synoviocytes and chondrocytes showed that BIO-PLY protected these cells of the joint from inflammation. The goal of this study was to test BIO-PLY for in vivo efficacy using an equine model of infectious arthritis. We found that horses experimentally infected with S. aureus and subsequently treated with BIO-PLY combined with the antibiotic amikacin (AMK) had decreased bacterial concentrations within both synovial fluid and synovial tissue and exhibited lower systemic and local inflammatory scores compared to horses treated with AMK alone. Most importantly, AMK+BIO-PLY treatment reduced the loss of infection-associated cartilage proteoglycan content in articular cartilage and decreased synovial tissue fibrosis and inflammation. Our results demonstrate the in vivo efficacy of AMK+BIO-PLY and represents a new approach to restore and potentiate antimicrobial activity against synovial fluid biofilms.}, journal={Frontiers in Cellular and Infection Microbiology}, publisher={Frontiers Media SA}, author={Gilbertie, Jessica M. and Schaer, Thomas P. and Engiles, Julie B. and Seiler, Gabriela S. and Deddens, Bennett L. and Schubert, Alicia G. and Jacob, Megan E. and Stefanovski, Darko and Ruthel, Gordon and Hickok, Noreen J. and et al.}, year={2022}, month={May} } @article{stowe_fiebrandt_druley_taylor_2022, title={Implementation of a Fine Needle Aspirate Simulation Model}, volume={49}, ISSN={0748-321X 1943-7218}, url={http://dx.doi.org/10.3138/jvme-2020-0157}, DOI={10.3138/jvme-2020-0157}, abstractNote={Being able to appropriately perform fine needle aspiration (FNA) collecting techniques and sample preparation is essential in obtaining a diagnostic sample, which is a critical skill for veterinary practitioners. Collection and preparation of cytologic samples are skills gained through practice. Experience leads to refinement of technique and improved diagnostic quality. Using live patients for mass skills training is not feasible; therefore, an aspiration simulation model and laboratory session was developed to reinforce physical exam skills, appropriate selection of sample collection supplies, and collection technique. Materials for the models include Ping-Pong balls, silicone, instant vanilla pudding mix, water, and stuffed animals. The laboratory session allows veterinary students to practice lesion identification, isolation, aspiration, and successful preparation. Subsequent submission of the collected sample involves being able to expel and spread the sample on a slide and proper labeling. While the simulation experience was initially developed for a short course with 12 students, it has recently been incorporated into the required clinical pathology clinical year rotation for up to 100 fourth-year veterinary students.

The goal of this study was to evaluate the retention of veterinary clinical pathology knowledge between the fourth-semester and fourth-year clinical pathology courses. We hypothesize that students will forget a significant amount of content area knowledge between the fourth semester and fourth year in the Doctor of Veterinary Medicine (DVM) program. We further hypothesize that a review of material during the fourth-year clinical pathology rotation will help students rebuild existing knowledge and increase performance on specific test questions, between T2 (rotation pre-test) and T3 (rotation post-test). Initial mastery of course material was assessed via a 94-item multiple-choice final exam (T1) given in the semester 4 clinical pathology course. Retention of course material from semester 4 to year 4 was assessed via a 55-item multiple-choice pre-test, administered at the start of the clinical pathology rotation in year 4 while learning/mastery during the clinical rotation was assessed via a 55-item multiple-choice post-test, administered at the end of each clinical pathology rotation. In this study, evidence of knowledge retention between semester 4 and year 4 was 55.5%. There is a small increase in the measure of knowledge gain from the beginning to the end of the rotation. As an added benefit, we were able to use identified trends for retention of knowledge within specific subject areas as a mechanism to evaluate the effectiveness of our course and reallocate additional instructional time to topics with poorer retention.}, number={6}, journal={Journal of Veterinary Medical Education}, publisher={University of Toronto Press Inc.

Objective To compare cytology and culture of endotracheal and transtracheal washes and identify factors associated with discordancy and bacterial growth. Animals Two hundred forty-five dogs with respiratory disease. Methods Retrospective study. Tracheal wash submissions were included if cellularity was sufficient for cytologic interpretation and aerobic cultures were performed. Collection technique, cytology, bacterial growth, and antibiotic history were analyzed. Results Fewer transtracheal specimens (9/144, 6.3%) were excluded for hypocellularity than endotracheal (28/174, 16.1%); otherwise, results were similar and were combined. Of 281 specimens with cellularity sufficient for interpretation, 97 (34.5%) had bacteria on cytology and 191 (68.0%) had bacterial growth. Cytology positive/culture negative discordancy was uncommon (8/97, 8%). Cytology negative/culture positive discordancy was frequent (102/184, 55.4%), but occurred less often (28/184, 14.2%) when only 1+ growth or greater was considered positive. Oropharyngeal contamination was associated with bacterial growth, but not discordancy. No association was found between antibiotic administration and bacterial growth. Conclusions and Clinical Importance Endotracheal wash fluid, in particular, should be screened for gross mucus or turbidity to maximize the likelihood of an adequate specimen. Otherwise, endotracheal and transtracheal specimens were similar. Presence of bacteria on cytology was a good predictor of any growth, while their absence was a good predictor of the absence of growth of 1+ or more. Recent antibiotic usage should not discourage TW culture if there is compelling reason to avoid delay.}, number={2}, journal={JOURNAL OF VETERINARY INTERNAL MEDICINE}, author={Graham, Amber M. and Tefft, Karen M. and Stowe, Devorah M. and Jacob, Megan E. and Robertson, James B. and Hawkins, Eleanor C.}, year={2021}, month={Mar}, pages={1073–1079} } @article{mochizuki_stowe_2021, title={Hematologic and clinical characteristics of dogs with circulating macrophage-like cells}, volume={50}, ISSN={["1939-165X"]}, url={https://doi.org/10.1111/vcp.12962}, DOI={10.1111/vcp.12962}, abstractNote={Background Macrophage-like (ML) cells are rarely observed on blood smear examinations, and the significance of these cells has been poorly described. Objective The objective of this study was to retrospectively describe selected hematologic and clinical characteristics of dogs with ML cells in peripheral blood. Materials and Methods Complete blood count (CBC) reports with blood smear evaluations from the clinical pathology laboratory records at North Carolina University College of Veterinary Medicine were retrospectively reviewed. Data were collected over a 10-year-period. Dogs were defined as having circulating ML cells if three or more ML cells were present on a single blood smear. Hematologic and clinical data of dogs with circulating ML cells were compared with age-matched hospital-derived control dogs. Results Of 61,631 CBC records, 87 reports (0.14%) described the presence of ML cells. Thirty-nine dogs met the inclusion criteria. The hemogram of dogs with circulating ML cells was characterized by a pronounced inflammatory and stress leukogram, anemia, and thrombocytopenia. Of the 39 dogs, 19 (49%) had systemic or severe localized inflammatory/necrotic diseases. Eighteen (46%) dogs were diagnosed with neoplasia of histiocytic (5) and non-histiocytic origins (13). Dogs with circulating ML cells had a shorter median survival time (34 days) than the control dogs (595 days, P < .0001), with an increased occurrence of death/euthanasia within 1 month (3.89-fold). However, the presence of circulating ML cells was not found to be an independent prognostic factor in a multivariable model. Conclusions The hemograms and diagnoses of dogs with ML cells suggest that severe inflammatory conditions or histiocytic and non-histiocytic neoplasia are common causes for circulating ML cells.}, number={1}, journal={VETERINARY CLINICAL PATHOLOGY}, publisher={Wiley}, author={Mochizuki, Hiroyuki and Stowe, Devorah M.}, year={2021}, month={Mar}, pages={37–44} } @article{stowe_schoenfeld-tacher_hammond_hedgpeth_neel_2021, title={Impact of online courses and grading framework on student learning and motivation}, volume={4}, ISSN={2590-1761}, url={http://dx.doi.org/10.4103/ehp.ehp_27_21}, DOI={10.4103/ehp.ehp_27_21}, abstractNote={Background: At our institution, the COVID-19 pandemic led to an abrupt change from traditional in-person instruction to remote teaching along with a concurrent change from letter grades to satisfactory/marginal/unsatisfactory grading. Objectives: The aims of this study were to explore the effects of changes in instructional delivery on students’ learning and retention of the material and to assess students’ motivation to learn. Methods: The study consisted of two phases. Phase 1 involved the administration of an academic motivation survey and a clinical pathology exam using online platforms. Phase 2 involved conducting a focus group to further explore student experiences during the change in course instruction. Results: The academic motivation survey revealed that both prior to and during the pandemic, the main drivers for student achievement were an interest in learning the content due to anticipated relevance in clinical practice, as well as a desire to master course goals. While the students predicted feeling more confident in their data interpretation ability in the traditionally taught topics vs. topics modified due to social distancing, the data from the content exam suggests that students showed better retention of topics taught in a modified manner. Lastly, the focus group revealed that participants perceived online learning to be more challenging due to the lack of in-person contact and increased frustration with technical issues. Conclusion: While moving courses online may make it more difficult to engage with the materials, peers, and instructors, there did not appear to be adverse effects on the overall student learning or content retention.}, number={3}, journal={Education in the Health Professions}, publisher={Medknow}, author={Stowe, DevorahM and Schoenfeld-Tacher, ReginaM and Hammond, Sarah and Hedgpeth, Mari-Wells and Neel, JenniferA}, year={2021}, pages={99} } @article{didomenico_fowler_horne_bizikova_schnabel_stowe_2021, title={Pathology in Practice}, volume={258}, ISSN={0003-1488}, url={http://dx.doi.org/10.2460/javma.258.9.961}, DOI={10.2460/javma.258.9.961}, number={9}, journal={Journal of the American Veterinary Medical Association}, publisher={American Veterinary Medical Association (AVMA)}, author={DiDomenico, Amy E. and Fowler, Alexander W. and Horne, Caitlyn R. and Bizikova, Petra and Schnabel, Lauren V. and Stowe, Devorah M.}, year={2021}, month={May}, pages={961–964} } @article{marin_mochizuki_mastromauro_stowe_2021, title={What is your diagnosis?

Blood was collected from 12 eastern box turtles ( Terrapene carolina carolina ) and 12 marine toads (Rhinella marinus ) and analyzed via i-STAT CHEM8+ cartridges. Two undiluted samples and two samples diluted 1 : 1 with sterile water were evaluated immediately following collection for each animal in the study. Analytes reported in the diluted samples were limited to glucose, ionized calcium, and total carbon dioxide. The expected dilution ratio value of diluted to undiluted samples was 0.5, of which glucose in both turtles and toads was nearest. Dilution ratio values for ionized calcium, however, were higher than expected in both turtles and toads. Sample dilution is not recommended for most analytes included on the CHEM8+ cartridge due to values occurring outside the limits of detection for the analyzer.

Guidelines for optimizing assay performance and interpretation of results are limited, and concordance of results across laboratories is unknown. Objectives This study aimed to determine inter-investigator agreement on the interpretation of FC results from split samples analyzed in different laboratories using various protocols, cytometers, and software; and on the interpretation of archived FC standard (FCS) data files contributed by the different investigators. Methods This was a multicenter observational cross-sectional study. Anticoagulated blood or lymph node aspirate samples from nine client-owned dogs were aliquoted and shipped to participating laboratories. Samples were analyzed with individual laboratory-developed protocols. In addition, FCS files from a set of separate samples from 11 client-owned dogs were analyzed by participating investigators. A person not associated with the study tabulated the results and interpretations. Agreement of interpretations was assessed with Fleiss’ kappa statistic. Results Prolonged transit times affected sample quality for some laboratories. Overall agreement among investigators regarding the FC sample interpretation was strong (κ = 0.86 ± 0.19, P < .001), and for specific categories, ranged from moderate to perfect.

Normally expressed only in fetal or gametogenic tissues, CTAs are tantalizing immunotherapy targets, since autoimmunity risks appear minimal. Few prevalent CTAs have been identified in human hematologic cancers, and just two in their veterinary counterparts. We sought to discover new CTAs in canine hematologic cancers such as histiocytic sarcoma (HS) and lymphoma to foster immunotherapy development. To accomplish this, the ligandome binding the dog leukocyte antigen (DLA)-88*508:01 class I allele overexpressed in an HS line was searched by mass spectrometry to identify possible CTA-derived peptides, which could serve as CD8+ T-cell epitopes. Twenty-two peptides mapped to 5 human CTAs and 12 additional proteins with CTA characteristics. Expression of five promising candidates was then evaluated in tumour and normal tissue by quantitative and end-point RT-PCR. The ortholog of an established CTA, IGF2BP3, had unexpectedly high expression in peripheral blood mononuclear cells (PBMCs). Four other testis-enhanced proteins were also assessed. AKR1E2, SPECC1 and TPX2 were expressed variably in HS and T-cell lymphoma biopsies, but also at high levels in critical tissues, including kidney, brain and marrow, diminishing their utility. A more tissue-restricted candidate, NT5C1B, was detected in T-cell lymphomas, but also at low levels in some normal dog tissues. These results illustrate the feasibility of discovering canine CTAs by a reverse approach, proceeding from identification of MHC class I-presented peptides to a comparative RNA expression survey of tumours and normal tissues.}, number={3}, journal={Veterinary and Comparative Oncology}, publisher={Wiley}, author={Nemec, Paige S. and Kapatos, Alexander and Holmes, Jennifer C. and Stowe, Devorah M. and Hess, Paul R.}, year={2019}, month={Jun}, pages={317–328} } @article{foster_jacob_stowe_smith_2019, title={Exploratory cohort study to determine if dry cow vaccination with a Salmonella Newport bacterin can protect dairy calves against oral Salmonella challenge}, volume={33}, ISSN={0891-6640 1939-1676}, url={http://dx.doi.org/10.1111/jvim.15529}, DOI={10.1111/jvim.15529}, abstractNote={BACKGROUND Salmonellosis is a major cause of morbidity and mortality in neonatal calves, often occurring before preventative vaccines can be administered. HYPOTHESIS/OBJECTIVE To evaluate the protective effect on calves of colostrum from cows vaccinated with a commercially available Salmonella Newport bacterin against a Salmonella Typhimurium challenge. ANIMALS Twenty Holstein bull calves from a university dairy farm. METHODS Nonrandomized placebo-controlled trial in which colostrum was harvested from 30 cows that received 2 doses of either Salmonella bacterin or saline before calving. Colostrum collected from each group was pooled and fed to 2 groups of 10 calves at birth. At approximately 2 weeks of age, calves were challenged with Salmonella Typhimurium. Clinical, hematologic, microbiological, and postmortem findings were compared between the 2 groups. RESULTS No differences in mortality, clinical findings, hematology results, blood and fecal cultures, or necropsy findings between the 2 groups were observed. Vaccinated cows had higher colostral titers, and calves fed this colostrum had higher serum titers (mean difference, 0.429; mean [SE], 0.852 [0.02] for vaccinated versus 0.423 [0.02] for control calves). CONCLUSIONS AND CLINICAL IMPORTANCE Transfer of colostral immunoglobulins from Salmonella enterica serotype Newport bacterin to neonatal calves was not sufficient to decrease mortality, clinical signs, sepsis, intestinal damage, or fecal shedding when exposed to a highly pathogenic Salmonella isolate. A large-scale randomized controlled clinical trial is needed to evaluate the efficacy of this bacterin when administered in the dry period for prevention of salmonellosis in neonatal calves.}, number={4}, journal={Journal of Veterinary Internal Medicine}, publisher={Wiley}, author={Foster, D. and Jacob, M. and Stowe, D. and Smith, G.}, year={2019}, pages={1796–1806} } @article{mochizuki_sherrick_mastromauro_stowe_2019, title={What is your diagnosis?

Radiographs of the right stifle revealed a multiloculated lytic lesion of the distal femur, with a large open lytic zone centrally, numerous osseous septations peripherally, and focal areas of cortical thinning and loss. An aspirate of the right distal femoral lesion yielded mildly cloudy serosanguineous fluid. Cytologic examination of the fluid revealed a pleomorphic population of discrete cells that exhibited marked anisocytosis and anisokaryosis and a variable nuclear-to-cytoplasmic (N:C) ratio, which were interpreted as probable neoplastic cells, with few macrophages, and evidence of hemorrhage. Given the clinical signs of pain, lesion size, and concern for malignant neoplasia, amputation of the right hind limb was performed. Histologically, the lesion had undulating walls 1-3 mm thick with a continuous outer layer of dense fibrous tissue and an inner layer composed of reactive cancellous bone with no cortical compacta remaining. Remnants of thin fibrous or fibro-osseous septa projected from the bony wall into the cyst lumen. The final histologic diagnosis was a benign multiloculated solitary (unicameral) bone cyst of the distal right femur. Based on the histopathologic findings, it was speculated that the cells identified on cytology were a mixture of developing osteoclasts, osteoblasts, endothelial, and stromal cells.
