摘要 目的:了解我院分离的大肠埃希菌临床分布和耐药特点,为临床合理用药和控制大肠埃希菌感染提供依据。方法:收集临床分离的大肠埃希菌231株,采用纸片扩散法(K-B法)进行14种抗菌药物敏感性测定及产ESBLs耐药菌株的初步筛选,再通过双纸片协同试验(DDST)法确认产酶菌株。结果:231株大肠埃希菌标本来源,痰分离出86株(37.23%)、其次为尿液57株(24.68%)、胆汁39株(16.88%)等;产ESBLs大肠埃希菌阳性检出率为36.36%(84株);产ESBLs大肠埃希菌耐药率明显高于非产ESBLs大肠埃希菌。对氨苄西林、哌拉西林、萘定酸、环丙沙星、左氧氟沙星、庆大霉素的耐药率较高,对阿米卡星、头孢吡肟的耐药率较低,对亚胺培南耐药率为零。结论:产ESBLs大肠埃希菌具有多重耐药性,要重视产ESBLs菌株的检测,治疗其所致感染时,需根据药敏结果合理选用有效抗菌药物。
