Resistance and Homology Analysis of Acinetobacter baumannii / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the resistance and the homology of the Acinetobacter baumannii(ABA) strains isolated from inpatients to offer basis for clinical treatment and preservation.METHODS VITEK2-compact system was used to identify 110 ABA strains,and detect their susceptibility to antibiotics.REP-PCR was carried out to detect their homology.RESULTS The 110 isolated strains were multidrug resistant.Rate of sensitivity to amikacin was 91.3%,Rates of resistance to ceftazadime,ciprofloxacin and imipenem were 100.00%,97.83% and 91.30%,respectively.REP-PCR was confirmed part of them was from the same clone.CONCLUSIONS Most of the isolated strains are multidrug-resistant.The same clone of MDR-ABA probably leads to transmission among patients.
