Resistance rates of Staphylococcus pseudintermedius 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. The most common coagulase-positive Staphylococcus spp. in both dogs and cats was S. pseudintermedius (91.7% of dogs and 70.8% of cats), followed by S. aureus (4.5% of dogs and 29.2% of cats). In addition, S. schleiferi subsp. Coagulans was collected from dogs (3.0%) and S. intermedius (0.8%) from cats.
In S. pseudintermedius, resistance to tetracycline (TC), chloramphenicol (CP), erythromycin (EM), azithromycin (AZM), and ciprofloxacin (CPFX) in dog- and cat-derived strains was observed to exceed 40%, as was oxacillin (MPIPC) resistance in strains isolated from cats. On the other hand, gentamicin (GM) resistance was below 10% in strains isolated from dogs. The rates of resistance to critically important antimicrobials for human medicine in dog- and cat-derived strains respectively were as follows: 53.3% and 66.7% to AZM, and 58.2% and 88.2% to CPFX.
