From November 2002 to November 2003 carbapenem resistant Pseudomonas aeruginosa strains isolated from intensive care unit were collected prospectively. Twenthy seven nonduplicated isolates were evaluated. MIC values of meropenem (MP) and imipenem (IP) were detected by Etest. Ceftazidime( CAZ), aztreonam( ATM), piperasillin+tazobactam (TZP) susceptibilities of starins were determined by disk diffusion test. Screening for metallo beta-lactamase (MBL) production was carried out in these isolates by Etest. Seventen strains out of 27 were found as MBL producers.
