ABSTRACTWe aimed to examine the effects of resistance mechanisms on several resistance phenotypes among carbapenem-resistantKlebsiella pneumoniaeisolates with borderline carbapenem MICs. We compared carbapenemase-negativeK. pneumoniaewith carbapenemase-producingK. pneumoniae(CPKP) isolates with similar MICs. CPKP isolates exhibited a marked inoculum effect and were more resistant to the bactericidal effect of meropenem. This suggests that MIC measurements alone may not be sufficient in predicting the therapeutic efficacy of carbapenems against CPKP.
