Evaluation of the modified carbapenem inactivation method and sodium mercaptoacetate-combination method for the detection of metallo-β-lactamase production by carbapenemase-producing Enterobacteriaceae
CIM and mCIM were useful to screen for carbapenemase-producing Enterobacteriaceae. mCIM with carbapenem-SMA combination was valuable for metallo-β-lactamase detection. The SMA-mCIM had 100% sensitivity and specificity to detect metallo-β-lactamase.
