摘要 目的研究一株多重耐药肺炎克雷伯菌的耐药机制。方法采用微量肉汤稀释法测定该菌株对亚胺培南、美罗培南等18种临床常用药物的最低抑菌浓度(MIC)。通过质粒提取、聚合酶链反应(PCR)扩增和耐药基因克隆测序分析该菌株耐药机理。结果该菌对所测临床常用药物均耐药,对美罗培南和亚胺培南的MIC值均为256μg/ml,美罗培南/克拉维酸和亚胺培南/克拉维酸的MIC值分别为256μg/ml和128μg/ml。PCR产物电泳示扩增条带大小为1050bp左右,与预计相符,经测序和在线比对,证实为KPC-2型编码基因。结合药敏结果,不排除该菌还存在其他耐药机理。结论该菌株质粒上携带KPC-2编码基因,临床抗生素运用须谨慎,医院感染防护需加强。
