ABSTRACT β-Lactam susceptibility of 499 Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae , determined by reference broth microdilution, demonstrated that 14.4% of isolates were categorized as cefepime susceptible according to current CLSI breakpoints. Ceftazidime- and meropenem-susceptible isolates were also observed (2.6 and 3.0%, respectively). Cefepime-susceptible KPC-producing isolates may confuse laboratory staff and clinicians in their therapeutic choices.
