Genotyping Analysis of Nosocomial Acinetobacter baumannii Strains

Abstract

The problem of genotypic variety of Acinetobacter baumannii isolated from patients with healthcare associated infections (HCAIs) are discussed. Carbapenemresistant strains, which are predominant in the study region, were shown to belong to the epidemic clonal line II and carry 1st class integron in their genome. Fraction of integron-positive isolates in HCAIs may be an indicator of nosocomial population of A. baumannii. The genes (gene cassettes) of integrons determine resistance to aminoglycosides, but not carbapenems.
