Japanese Veterinary Antimicrobial Resistance Monitoring System (JVARM)
The monitoring of antimicrobial resistance was conducted on 5 agents that had efficacy against photobacteriosis from 2011 to 2014. The number of tested strains was small, and the proportion of resistance varied particularly for ampicillin (ABPC) and for oxolinic acid (OA). However, the proportion of the resistance remained at 7.1% or lower both for bicozamycin (BCM) and for fosfomycin (FOM). Although the proportion of florfenicol (FF) resistant strain was not calculated given that no bimodal MIC distribution was observed, MIC values were low (≤ 1) in all strains, suggesting that the susceptibility was maintained.
