Quaternary Ammonium Compounds-resistant Genes and Class Ⅰ Integrase Genes in Continuously Isolated Acinetobacter baumannii / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the resistance and the genes of quaternary ammonium compounds-resistance(qacE△1) and classⅠintegrase genes(intⅠ1)in continuously isolated Acinetobacter baumannii(ABA).METHODS K-B tests were performed to detect the susceptibility of 85 strains of ABA to 13 kinds of antimicrobial agents.The qacE△1 and intⅠ1 genes were analyzed by PCR.RESULTS The resistant rates to antimicrobial agents were between 8.2% and 81.2%.qacE△1 And intⅠ1 genes were 77.6%.CONCLUSIONS The 85 ABA strains are multiple-drug-resistant.There are very high positive percentages of qacE△1 and intⅠ1 genes in ABA isolated from Shaoxing,Zhejiang Province.
