Quaternary Ammonium Compounds Resistant Gene of Multiple Drug Resistant Acinetobacter baumannii / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigae the gene resistant to quaternary ammonium compounds of multiple drug resistant Acinetobacter baumannii(MDR-ABA).METHODS The quaternary ammonium compounds qacE?1 gene in 20 MDR-ABA strains were detected by PCR.RESULTS The 20 MDR-ABA strains showed multiple resistance,its sensitivity to imipenm was 65% only.Among twenty strains of MDR-ABA qacE?1 gene were all positive.CONCLUSIONS The results indicate that qacE?1 gene were all carred class 1 integron.The chlorhexidine usage in prevnting hospital infection after surgery should be reevaluated.
