1533. Is Cation-Adjusted Mueller–Hinton Broth (CAMHB) Appropriate for Metallo-β-lactamase (MBL) Susceptibility Testing? Novel Insights in In Vitro–In Vivo Discordance Among MBL-Producing Enterobacteriaceae
BACKGROUND: MBLs, which require Zn for catalytic activity, are a major contributor to high-level β-lactam resistance when tested using conventional CAMHB. We have previously reported marked reductions in meropenem (MEM) MICs in Zn-depleted media (Chelex-CAMHB and EDTA-CAMHB; Zn [C] <0.002 mg/L) c...
