777株临床分离肠球菌的分布及耐药性分析

目的了解本院临床肠球菌的菌群分布及耐药情况。方法采用回顾性调查分析方法对我院分离自各类临床标本的777株肠球菌进行统计,并对抗菌药敏试验结果进行分析。结果肠球菌菌株来源以尿液(30.5%)、胆汁(25.5%)、分泌物(17.8%)为主;2007～2010年分离的肠球菌对抗生素的耐药率有逐年增高趋势(P<0.05);屎肠球菌对多种抗生素的耐药率明显高于粪肠球菌,且在分离的肠球菌构成比有增高趋势。结论屎肠球菌在临床分离的肠球菌中越来越常见,肠球菌的多重耐药严重。

Distribution of Enterococcus isolated from clinic samples of 777 strains and surveillance of antimicrobial resistance

Objective To evaluate the distribution of isolated from clinical samples and bacterial resistance to antimicrobial agents.Methods Identification and antimicrobial susceptibility tests were performed in clinical isolates of 777 enterococcus.Results The strains were mainly isolated from the urinary enterococcal isolates(30.5%),bile(25.5%),discharge(17.8%) dominated;2007 and 2010 enterococci isolated resistance to antibiotics has increased year by year trend rate(P<0.05);feces resistant to several antibiotics of enterococci was significantly higher than that of Enterococcus faecalis and Enterococcus faecium in the separation of the constituent ratio tended to increase.Conclusion Excrement enterococcus in clinical isolates of enterococcus became more and more common,enterococcus multiple drug-resistant was alao seriously.
