Antimicrobial resistance rates and MIC distributions of CRKP isolates.

MIC (μg/ml)
Cutoff value of resistance (%) Range MIC50 MIC90
COL >2 (92.5%) 2~32 8 16
MEM ≥4 (100%) 4~256 16 128
AMK ≥16 (97.5%) 1~16384 4 8

MIC, minimum inhibitory concentration; AMK, amikacin; MIC50, MIC at which 50% of the isolates tested are inhibited; MIC90, MIC at which 90% of the isolates tested are inhibited; COL, colistin; MEM, meropenem.
