Farms were either finishing sites using all-in/all-out management of buildings in multiple-site systems (14 farms) or farrow-to-finish systems using continuous-flow management of finishing barns or outdoor accommodation 14 farms). The two groups of herds differed with respect to several management variables. A total of 13 of 2238 samples (0.58%) were positive for antibodies to Toxoplasma gondii using the modified agglutination test. Of these, 12 were from 63 pigs sampled on a farm where finishing pigs were kept on pasture. Only one of 1752 (0.057%) samples from pigs kept in total confinement systems was seropositive. Only one pig of 2183 (0.046%) tested positive by ELISA for antibodies against T. spiralis. In this region, management practices in modern production systems appear to be adequate to virtually eliminate the risk of infection of finishing pigs with both T. gondii and T. spiralis.}, number={1}, journal={PREVENTIVE VETERINARY MEDICINE}, author={Davies, PR and Morrow, WEM and Deen, J and Gamble, HR and Patton, S}, year={1998}, month={Jul}, pages={67–76} }

The half‐life for enrofloxacin following i.m. administration was 28.9 h, considerably longer than values calculated for other animals such as dogs, birds, rabbits, and tortoises. The 4 h maximum concentration (Cmax) of 1.64 μg/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 μg/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 μg/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. Ciprofloxacin, an active metabolite of enrofloxacin, was detected and measured after all methods of drug administration. It is possible and practical to obtain therapeutic blood concentrations of enrofloxacin in the red pacu using p.o., i.m., and bath immersion administration. The i.m. route is the most predictable and results in the highest plasma concentrations of the drug.}, number={2}, journal={JOURNAL OF VETERINARY PHARMACOLOGY AND THERAPEUTICS}, author={Lewbart, G and Vaden, S and Deen, J and Manaugh, C and Whitt, D and Doi, A and Smith, T and Flammer, K}, year={1997}, month={Apr}, pages={124–128} }
