Detection of VIM- and IMP-type metallo-beta-lactamase genes in acinetobacter baumannii isolates from patients in two hospitals in Tehran

ABSTRACT

Background: acinetobacter baumannii, is an opportunistic pathogen and is responsible for numerous nosocomial infections. In recent years, this microorganism has been resistant to a wide range of antibiotics. One of the most important mechanisms of resistance in this microorganism is production of metallo-beta-lactamases [MBLs]
