Japanese Veterinary Antimicrobial Resistance Monitoring System (JVARM)
Monitoring of antimicrobial resistance on 15 agents was carried out in 2017. Resistance to ampicillin (ABPC), cefazolin (CEZ), cephalexin (CEX), cefotaxime (CTX), nalidixic acid (NA), and sulfamethoxazole-trimethoprim (ST) in dog- and cat-derived strains was observed to exceed 40%, as was resistance to streptomycin (SM), gentamicin (GM), and tetracycline (TC) in cat-derived strains. On the other hand, resistance to colistin (CL) in dog- and cat-derived strains was less than 10%, as was resistance to kanamycin (KM) in strains isolated from dogs and fosfomycin (FOM) in those isolated from cats. The rates of resistance to critically important antimicrobials for human medicine in dog- and cat-derived strains respectively were as follows: 41.7% and 80.8% to CTX; 1.4% and 3.8% to colistin (CL); and 44.4% and 84.6% to ciprofloxacin (CPFX). No resistance to meropenem (MEPM) was observed.
* BP follows CLSI Criteria.
† BP for FOM uses values for E. coli, while EUCAST values were used as the BP for CEX and CL. As EUCAST has not set a BP for SM, the JVARM value (midpoint of a bimodal MIC distribution obtained in FY2001) was used.
