Japanese Veterinary Antimicrobial Resistance Monitoring System (JVARM)
Monitoring of antimicrobial resistance on 15 agents was carried out in 2017. Ampicillin (ABPC) and nalidixic acid (NA) resistance in dog- and cat-derived strains was observed to exceed 40%, as was ciprofloxacin (CPFX) resistance in dog-derived and cephalexin (CEX) resistance in cat-derived strains. On the other hand, the rate of resistance to kanamycin (KM), colistin (CL), and fosfomycin (FOM) in strains isolated from dogs and cats was less than 10%. The rates of resistance to critically important antimicrobials for human medicine in dog- and catderived strains respectively were as follows: 26.1% and 33.8% to cefotaxime (CTX); 1.0% and 0.0% to CL; and 43.2% and 39.0% to ciprofloxacin (CPFX). No resistance to meropenem (MEPM) was observed.
