190株肠球菌的鉴定及药敏分析

目的了解黑龙江省医院肠球菌的菌种分布及对常用抗生素耐药性的现状。方法对2004年8月至2006年6月检出的190株肠球菌的菌种鉴定及药敏结果进行回顾性分析。结果粪肠球菌(46.3%)分离率下降;屎肠球菌(33.2%)、鹑鸡肠球菌(13.7%)分离率增加。耐药株检出率屎肠球菌为85.1%,粪肠球菌为75.0%,鹑鸡肠球菌为70.2%。青霉素和呋喃妥因对粪肠球菌引起的感染有一定的疗效,万古霉素,替考拉宁是治疗肠球菌引起感染的最佳选择。结论肠球菌已成为引起临床感染的重要致病菌,它的天然耐药和多重耐药的特性使得临床可选治疗药物范围狭窄。应防止耐万古霉素肠球菌株的产生。

Identification and sensitivity analysis of 190 strains of Enterococcus

Objective To explore the current distribution and antibiotic resistance of enterococci in Heilongjiang Provincial Hospital.Method 190 enterococcus strains isolated from August 2004 to June 2006 were identified and their antimicrobial susceptibility consequence were retrospectively analyzed.Result The isolating rate of Enterococcus faecalis(46.3%) decreased,while the isolating rate of Enterococcus faecium(33.2%) and Enterococcus gallinarum(13.7%) increased.The detection rate of the persisters of Enterococcus...
