2009年至2011年医院革兰阳性菌耐药性分析

目的分析2011年至2013年医院革兰阳性菌耐药性变化，为临床合理用药提供依据。方法提取3年全院临床标本中革兰阳性茵株进行药敏分析。结果金黄色葡萄球菌分离率70．39％，其次是表皮葡萄球菌，均对万古霉素、利奈唑胺有较高的敏感率（达95％以上），对复方新诺明敏感率达70％～80％，粪肠球菌只对万古霉素和利奈唑胺敏感。结论该院近3年耐甲氧西林金黄色葡萄球菌（MR—SA）分离率超90％，值得关注。

Objective Analyse gram-positive bacteria resistance changes from 2011-2013 in our hospital so as to provide reference for rational use of antibacterials in clinics.Methods Collecting strains of Gram-positive bacterias of all samples were performed drug sensitivity analysis in our hospital during three years.Results The isolated rate of staphylococcus aureus belong to first （70.9%）, the second is S.epidermidis .they all were sensitive to Vancomycin and Linezolid （95%）,the sensitive rate to Trimethoprlm/sulfa is 70%-80%.The drug resistance rate of fenchangqiujun to the commonly used antibiotics were high except for Vancomycin and Linezolid, Conclusion The isolated rate of Meticillin-resistant S.aureus and S.epidermidls from Jan 1st 2009 to Dec 31st 2011 were an average of 90% ,so shoud be given attention.
