肠球菌在尿液标本中的分布及其耐药性分析

Analysis of drug-resistance and distribution of Enterococcus spp.isolated from urine

目的:研究尿液中肠球菌的分布及其耐药性。方法:分析2007年1月-2010年12月尿液标本中分离出的肠球菌分布和耐药性。结果:尿液标本中粪肠球菌较多见,但屎肠球菌和铅黄球菌检出率增高较快。屎肠球菌对青霉素类、呋喃妥因、喹诺酮类、高浓度庆大霉素、高浓度链霉素和利福平的耐药性明显高于粪肠球菌,而对四环素耐药性低于粪肠球菌。结论:尿液中以粪肠球菌为主。肠球菌的耐药性日趋严重,甚至出现了万古霉素耐药肠球菌。

Objective：To study the drug-resistance and distribution of Enterococcus in urine specimens.Methods： The clinical distribution and antibiotic resistance of Enterococcus collected from January 2007 to December 2010 were analyzed.Results： There were mainly Enterococcus faecalis in the urine specimens,but the positive rate raised faster in E.faecium and E.casselifavus.The antimicrobial resistance of E.faecium was significantly higher than that of E.faecalis to Benzylpenicillin,Nitrofurantoin,Quinolone,high concentration Gentamycin,high concentration Streptomycin and Rifamycin but lower to Tetracycline.Conclusion： There were mainly E.faecalis in the urine specimens.The drug-resistance of Enterococcus is more and more serious,and the Vancomycin-resistant Enterococci（VRE） even come to be present.
