Abstract
This study determined the effectiveness and oral absorption of oxytetracycline (OTC) in rainbow trout (Oncorhynchus mykiss) experimentally infected with an Aeromonas salmonicida challenge strain (MIC = 0.25 μg/mL). The FDA-approved OTC-medicated feed regimen was shown to be highly efficacious. A follow-up parallel study revealed a clear and direct correlation between serum OTC and serum total protein (TP) concentrations in A. salmonicida-challenged rainbow trout 1, 3, 4, 6, and 10 days after medicated dosing began. Mean serum OTC concentrations collected at various time points during the dosing regimen were lower in A.salmonicida-challenged rainbow trout than previously shown in healthy uninfected trout.
