Abstract:ObjectiveTo analyze the genotype and homology of drug resistance gene in carbapenemase resistant Acinetobacter baumannii(CRAB).Methods68 strains of CRAB isolated from January 2013 to August 2014 were included in our retrospective analysis.Multiplex Polymerase Chain Reaction(Multiplex-PCR)was conducted to analyze six types of β-lactamase resistant gene IMP,VIM,OXA-23,OXA-24,OXA-58,OXA-51 in these strains of CRAB,and the gene homology of 8 CRAB isolateswere analyzed by pulsed field gel electrophoresis(PFGE).ResultsAll of the 68 isolates of CRAB were found to carry OXA-23,OXA-51,but not IMP,VIM,OXA-24,OXA-58.The result of PFGE suggested that the 8 CRAB isolates might derived from the same clone.And the gene homology analysis showed high homology among them.ConclusionAll the 68 CRAB strains isolated from our hospital belong to the same clone and carry OXA-23,OXA-51 genes mainly,indicating that there is clone spread among CRAB isolates.
