肠球菌医院感染分布及耐药监测

Study on Distribution and Antibacterial Resistance of Nosocomial Infection of Enterococcali

目的 了解肠球菌院内感染分布及耐药特性。方法 英国SENSITIRE(先德)荧光快速微生物鉴定／药敏分析仪进行细菌鉴定及药敏试验,用纸片扩散法进行庆大霉素高水平耐药筛选试验。结果 肠球菌感染以泌尿道感染为主,占50.5％。肠球菌表现多重耐药,不同菌种对氨苄西林、利福平耐药率有明显差异,对常用抗生素的耐药率,屎肠球菌明显高于粪肠球菌,HLGR株明显高于低耐株。结论 肠球菌对抗茵药物耐药谱有明显差异,合理选择抗生素,对控制院内感染有重大意义。

Objective To acquire the informattion about the present resistance characteristics and hospital infection in enterococci. Methods The Enterococci isolated and the susceptibility testing were used by the Sensititre Microbiology System. Results The enterococci infection with the urinary track were 50.5 % ; The test showed the Enterococci with multiresistanl to antibiotics; The Enterococcus faecium and HLGR Enterococci were more resistant to common antibiotics than Enterococcus faecalis and low - level gentamicin resistant enterococci respectively. Conclusions The species level should be identified and different enterococci need different antibiotic regimens.
