Resistance to imipenem and meropenem was observed in 211 (16.5%) isolates of Pseudomonas aeruginosa recovered in a Greek university hospital during 1996 to 1998. In six isolates selected from throughout this period, high-level resistance to both carbapenems (MICs ≥ 128 μg/ml) was associated with production of the class B β-lactamase VIM-1. bla VIM -bearing isolates belonged to serotype O:12 and were indistinguishable by pulsed-field gel electrophoresis. |
