摘要 目的统计某院患者分离的肺炎克雷伯菌临床分布及耐药性分析,为临床治疗肺炎克雷伯菌感染合理使用抗菌药物提供依据。方法收集2012—2016年从临床各种标本分离的肺炎克雷伯菌,共1 192株,菌种鉴定采用VITEK-2Compact微生物鉴定系统,药敏试验按照美国临床和实验室标准协会(CLSI)推荐的标准进行结果解释。结果 1 192株肺炎克雷伯菌,主要分离自痰液(65.6%);其科室分布主要以呼吸内科和MICU为最多,占41.4%;1 192株中检出产超广谱β-内酰胺酶(ESBLs)448株,占37.6%;并且连续5年产ESBLs的肺炎克雷伯菌的检出率有逐年上升趋势,比同期全国细菌耐药网(CARSS)公布的全国平均的数据都偏高;产ESBLs肺炎克雷伯菌耐药率明显高于非产ESBLs株。结论肺炎克雷伯菌引起的感染以下呼吸道为主,产ESBLs肺炎克雷伯菌对其药敏谱中抗菌药物的耐药率维持在较高水平,因此临床治疗肺炎克雷伯菌引起的下呼吸道感染一定要根据是否产ESBLs及其药敏结果合理选用抗菌药物。
