Evaluation of the Vitek 2 AST-N269 Card for Detection of Meropenem Resistance in Imipenem-Susceptible Meropenem-Resistant Enterobacteriaceae

In a recent article, Harino et al. evaluated the ability of several commercial automated susceptibility testing systems for the detection of the meropenem resistance of imipenem-susceptible meropenem-resistant (ISMR) null Klebsiella pneumoniae null due to the production of both CTX-M-2 and IMP-6 (1). They reported that the Vitek 2 AST-N124 card was unreliable for the detection of ISMR null Klebsiella pneumoniae null because of falsely low...
