Resistance rates of Klebsiella spp. derived from diseased dogs and cats (%)[the proportion of antimicrobial resistance in animals]

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.
