Found tigecycline nonsusceptible (MIC of ≥2 μg/ml) by EUCAST criteria on previous BSAC agar dilution testing. Seven isolates had KPC, 9 had NDM, 7 had OXA-48, and 5 had VIM enzymes. All other groups were included without reference to prior tigecycline (or other tetracycline) results.
Nine or ten representatives of each OXA-carbapenemase type listed.
Found tigecycline nonsusceptible (MIC of ≥2 μg/ml) by EUCAST criteria for Enterobacteriaceae on previous BSAC agar dilution testing.
