摘要 目的:研究老年人尿路感染临床分离菌的耐药情况。方法:采用纸片扩散法(K-B法)对1999年5月-2003年4月本院临床分离菌株进行药敏试验。结果:本院老年人尿路感染以革兰阴性杆菌为主,占77.3%(721株/933株),常见致病菌为大肠埃希菌、克雷伯菌属、肠杆菌属、不动杆菌属、假单胞菌属和变形杆菌属。对环丙沙星、氨曲南、头孢哌酮、头孢曲松和头孢他啶的耐药率分别达17.8%~73.5%、35.2%~73.9%、52.4%~64.3%、76.9%~87.2%、28.6%~62.9%和7.7%~53.8%,对阿米卡星耐药率为20.0%~65.1%;大多数菌株对亚胺培南敏感,耐药率为0%~3.8%。革兰阳性球菌分离率为19.5%(182/933株),均对万古霉素敏感,其中耐甲氧西林葡萄球菌占47.8%(87株/182株).未分离出甲氧西林敏感金黄色葡萄球菌。结论:老年人尿路感染的细菌耐药性严重,应定期监测细菌的耐药趋势,以指导用药。
