【摘要】目的 研究该院检出的348株铜绿假单胞菌(PAE)耐药性及多重耐药PAE耐药基因检测.方法 将血液科检出348例PAE菌株进行体外耐药监测,并对其中36株多重耐药PAE菌株进行耐药相关基因OprD2、VIM、GIM、SPM、IMP-1、TEM、VEB、PER、aac (3)-Ⅲ、aac (6)'-Ib-Cr、qnrA、qnrS、qnrD检测.结果 多重耐药PAE对妥布霉素、哌拉西林/他唑巴坦、美罗培南比较敏感,对其他临床常用抗生素均有明显的耐药性,PCR基因分析结果显示,OprD2和IMP-1基因阳性率分别为97.22%和94.44%,aac (3)-Ⅲ和aac(6)'-Ib-Cr阳性率分别为38.89%和27.78%,TEM阳性率为75.00%,qnrA、qnrS和qruD阳性率为50.00%、61.11%和47.22%,其他基因低于15.00%.结论 PAE耐药性较强,多重耐药PAE耐药基因主要为OprD2和IMP-1基因.%Objective To investigate the drug resistance of 348 strains of Pseudomonas aeruginosa (PAE) and detection of drug resistance genes of multidrug-resistant PAE in our hospital.Methods In vitro resistance monitoring was performed in 348 strains of PAE isolated in the Department of Hematology.In the 36 multi-drug resistant strains of PAE,RT-PCR was used
