초록
This study was performed to delineate pharmacokinetic residue characteristics of lincomycin (LM) in olive flounder at low water temperature (13℃), and to examine whether LM is effective against main Gram-negative pathogens. It was observed that the times for residue declined below the maximal residue limit (0.1 mg/kg) in the muscle was, respectively, 32, 33 and 55 days following 10, 20 and 40 mg/kg intramuscular LM injections. The in vitro MIC value of LM against Edwardsiella piscida was higher than 256 μg/mL and against Vibrio harveyi 32 μg/mL when examined with several clinical isolates. These results suggest that the withdrawal time of LM should be more than 30 days in consideration of the 10 mg/kg employed as the regular clinical dose. It was also found that LM administered to treat streptococosis in olive flounder is not likely to be effective against some pathogenic Gram-negative bacteria.
