目的统计分析2011—2014年我院分离的肠杆菌科细菌数据,探讨耐碳青霉烯肠杆菌科细菌(CRE)的流行特征。方法收集肠杆菌科细菌,根据药敏结果筛选出CRE菌株,并对相关临床资料进行统计分析。结果共分离得到CRE菌株187株,标本来源依次为尿液(32.6%)、痰液(28.9%)和血液(10.7%)。从科室分布来看,39.0%的菌株来自重症监护室病区,23.0%的菌株来自泌尿外科病区,在其它病区呈散发分布。菌株的种属分布方面,肺炎克雷伯菌的比例为39.6%, 大肠埃希菌的比例为20.9%;从病人年龄构成来看,50岁以上高龄患者的分离比例达74.4%。CRE的分离数目随年份的递增而不断升高。结论耐碳青霉烯肠杆菌科细菌的流行率呈现逐年递增的趋势,临床应合理使用相关抗生素,预防和控制CRE在医院环境中的流行。
