文档介绍：医院和社区获得性金黄色葡萄球菌耐药性比较
【摘要】目的比较医院获得性与社区获得性金黄色葡萄球菌的耐药性,以期为临床有效防治金黄色葡萄球菌的感染提供科学的用药依据。方法2007—2009年,收集我院及部分周边医院从各临床标本中分离出的不重复金黄色葡萄球菌菌株,将其分为社区获得性与医院获得性金黄色葡萄球菌组,各组随机取50株作为研究对象,对两组的耐药率进行比较。结果医院性感染和社区性感染的标本类型和科室来源不同(χ2=、,P<);医院获得性金黄色葡萄球菌较社区获得性金黄色葡萄球菌耐药性高(χ2=~,P<),且耐甲氧西林金黄色葡萄球菌的检出率高(χ2=,P<)。结论医院获得性与社区获得性金黄色葡萄球菌对阿莫西林-棒酸、头孢唑啉、苯唑西林、左氧氟沙星、奎奴普丁-达福普汀等的耐药性差异明显。

[ABSTRACT]pare drug resistance of hospital-munity-acquired us aureus (SA), so as to provide scientific medication for the control of SA un-repeated SA strains were isolated from clinical samples collected in 2007—2009 from our hospital munity hospitals, which were divided munity-acquired and hospital-acquired group. Fifty strains were taken in random served as a study object, and drug resistance between them pared. ResultsThe resistance rate of hospital-acquired SA was higher than that mun
ity-acquired (χ2=-,P<), and the detection rate of methicillin-resistant us aureus was also high in hospital-acquired differences between hospital-munity-acquired us aureus were significant in terms of the drug resistance to Amoxicillin-clavulanic acid, cefazolin, oxacillin, levofloxacin,and quinupristin/dalfopristin.
