摘要 目的 了解大肠埃希菌对部分抗菌药物的敏感和耐药情况,同时对耐药性原因加以分析和探讨。方法 按照《全国临床检验操作规程》(第2版)有关章节进行实验,并收集相关资料进行分析。结果 38株大肠埃希菌对丁胺卡那霉素、先锋必和呋喃妥因敏感率最高,分别为57.9%、52.6%和50.0%;对氟哌酸、先锋Ⅴ次之,敏感率分别为44.7%和39.5%;对氨曲南、头孢曲松、庆大霉素、哌拉西林和氨苄西林的敏感率局限在18.4%-26.3%之间;而对羧苄西林和环丙沙星耐药率最高,分别为86.8%和89.5%。结论 经实验证实,大肠埃希菌对抗菌药物的敏感度有不同程度的下降,使耐药菌株呈现上升趋势,这与医院对使用抗生素的管理、指导不善和医务人员不合理应用抗生素等原因有关。
