医院内革兰阳性球菌感染的调查及耐药分析

目的:了解医院内感染的革兰阳性球菌的分布及耐药情况,指导临床医生合理应用抗生素,防止耐药菌株的爆发流行。方法:药敏试验采用K-B纸片扩散法,用WHONET5软件进行统计学分析。结果:革兰阳性球菌在院内感染中所占比例为25%,主要是肠球菌(VRE)和葡萄球菌,VRE对所监测的抗生素均有不同程度的耐药,金黄色葡萄球菌(MRS)除未发现万古霉素耐药外对其他监测的抗生素均有不同程度的耐药。结论:革兰阳性球菌在医院感染中仍占有重要地位,MRS和VRE的感染较常见,对革兰阳性球菌进行规范的耐药监测工作是十分必要和重要的。

Clinical Analysis of Resistance and Survey of Gram Positive Cocci Infection in Hospital

Objective To understand distribution and resistant of gram positive cocci in hospital infection, and to direct clinical doctor use antibiotics with reason, and to prevent resistant strains outbreak and prevalence. Methods Antibiotic susceptivity test was done by Kirby-Bauer method. The result was analyzed by WHONET5 software. Results Gram positive cocci were 25% in hospital infection ,which enterococei and staphylococci were major. Enterococcus expressed resistance to antibiotics to some degree. Stapylococcus aureus expressed resistance to antibiotics to some degree except for vancomycin. Conclusion Gram positive cocci were still important in hospital infection. MRS and VRE was frequent appear. It is.quite necessary and important that we normatively monitor resistantce of gram positive cocci.
