Characterization of class 1 integrons in metallo-β-lactamase-producing Acinetobacter baumannii isolates from hospital environment.

The findings of the present study showed that the isolation rate of MBL producing carbapenem-resistant A. baumannii (CRAB) was relatively high in the environmental surface of burn wards and ICUs, which can be considered as a potential source of outbreaks in hospitalized patients.
