Emergence and dissemination of Enterobacteriaceae isolates harboring carbapenemases in various geographic regions represents a significant threat to the management of nosocomial infections. Enterobacteriaceae isolates from the SENTRY Antimicrobial Surveillance Program (2000-2004) demonstrating decreased susceptibility to imipenem and meropenem (minimum inhibitory concentration [MIC], > or =2 mg/L) were evaluated for the production of metallo-beta-lactamases and serine carbapenemases using disk approximation and polymerase chain reaction (PCR) tests. Carbapenemase-producing strains were epidemiologically typed by automated riboprinting and pulsed-field gel electrophoresis (PFGE) to establish clonality.
