老年患者泌尿道感染菌群分布及耐药模式分析

目的 分析引起老年患者泌尿道感染的病原菌分布特点及耐药特征，补充泌尿道感染耐药监测中老年人群的资料。方法 利用全自动微生物鉴定系统VITEK-60对从老年患者分离的菌株进行鉴定和药敏试验。结果 肠道的正常菌群，如大肠埃希菌、肺炎克雷伯菌、粪肠球菌是老年患者泌尿道感染的主要致病菌，且真菌感染比例远高于其他人群，同时，分离株耐药程度较高。结论 引起老年患者泌尿道感染的病原菌分布及耐药性有其相应的模式特点，相关的研究分析结果对合理使用抗菌药物有重要意义。

Pathogens and Antibiotic Resistance in Aged Patients with Urinary Tract Infection

OBJECTIVE To investigate the distribution and antimierobial susceptibility of clinical isolates from the aged patients with urinary tract infection. METHODS Totally 1211 strains of germs were identified and susceptibility tests were performed using VITEK-60 system as recommended by the manufacturer. RESULTS The most common pathogens were Escherichia coli, Klebsiella pneumoniae, and Enterococcus faecalis. The infective rate of fungi was higher in the elderly. CONCLUSIONS Our data will be useful for reasonably choosing antimierobial agents in treatment of UTI in the aged.
