摘要
目的对60岁以上老年患者泌尿系感染的临床分离株分布常态和药物敏感性实验结果进行分析,为临床第一线提供可靠的科学数据。方法按照NCCLS标准对2000年7月至2005年7月本院住院和门诊就诊患者共计839株临床分离株采用纸片扩散法(K-B法)进行药物敏感性试验。结果本院老年人泌尿系感染的细菌以革兰氏阴性杆菌为主,占77.4%(649/839),常见致病菌有大肠埃希菌、克雷伯菌属、肠杆菌属和假单胞菌属。对环丙沙星、氨曲南、头孢哌酮、头孢曲松、头孢他啶和阿米卡星的耐药率分别达45.7%,54.6%,58.4%,82.1%,45.8%和30.8%;亚胺培南对大多数菌株敏感,其耐药率仅为1.7%。革兰氏阳性球菌的阳性分离率为22.6%(190/839),其中以葡萄球菌为主。均对万古霉素敏感。结论老年人泌尿系感染的菌株,其耐药情况较为严重,在临床上应注意对有症状老年性患者作实验室的细菌学检查,以监测细菌的耐药趋势。
Objective To analyse the results of experiments on clinical isolates normal distribution and drug sensitivity of over sixty- year patients with urinary tract infection,and to provide reliable and scientific data for clinical front line.Methods A total of 839 isolates of inpatients and outpatients between September 2000 were abstracted by the standard of NCCLS,and theire drug sensitivity were analysed using K-B method.Results Urinary tract infection of old patients is mainly caused by Gram-Negative Bacillus,...
