Key Findings

The study describes the development of a sensitive microbiological assay (EIM) for detecting metallo-β-lactamases (MBLs) in nonfermentative gram-negative bacteria. It identifies several MBL genes, including bla VIM-11a, bla IMP-7, bla SPM-1, bla L1-like, bla GOB-like, bla IND-like, and bla BcII, which confer resistance to carbapenems.
