This isolate produced a metallo-beta-lactamase (MBL) whose gene, with 43.5% GC content, was cloned and expressed in Escherichia coli. beta-Lactamase DIM-1 (for Dutch imipenemase) was weakly related to other Ambler class B beta-lactamases, sharing <52% amino acid identity with the most closely related MBL, GIM-1, and 45% identity with IMP-type MBLs. The beta-Lactamase DIM-1 significantly hydrolyzed broad-spectrum cephalosporins and carbapenems and spared aztreonam. This MBL gene was embedded in a class 1 integron containing two other gene cassettes, encoding resistance to aminoglycosides and disinfectants, that was located on a 70-kb plasmid.
