In-vitro Antimicrobial Susceptibility of Pathogenic Bacteria in Rainbow Trout (Oncorhynchus mykiss, Walbaum)
MIC50 and MIC90 values of ciprofloxacin, trimethoprim-sulphamethoxazole, tetracycline and erythromycin for 39 fish pathogenic bacterial strains (Yersinia ruckeri, Enterococcus seriolicida, and Aeromonas salmonicida) were determined using the E-test and agar dilution method. The MIC50 value of ciprofloxacin was approximately 1 mg/l for all fish pathogenic isolates. All fish pathogenic isolates showed elevated susceptibility to ciprofloxacin.
