摘要
目的：了解本地区MRSA菌株的分子流行病学特点，明确本地区MRSA的基因型别及其分布规律。方法：收集2009年1月-2011年8月问鄂尔多斯地区门诊及住院患者非痰标本分离的MRSA菌株54株，应用SCCmec方法和spa方法进行基因分型。结果：应用SCCmec基因分型分离的MRSA以SCCmecⅡ、Ⅲ型为主，分别占本次分离的50％和46．4％；应用spa基因分型分离的MRSA以t030和t002为主，占该院分离率的41％和35．1％。结论：本地区分离MRSA以SCCmecⅢ—t030和SCCmecⅡ—t002为主。
Objective： This study will play an important role in tracking the genetic changes to chart the e- mergence, spread and evolution of MRSA in this region. Method： A total of 54 MRSA isolates were recovered from patients presenting with symptoms consistent with MRSA infection by the clinical microbiology laboratory in Ordos between 2009 1 and 2011 8, gene analysis by SCCmec genotyping and A gene polymorphism analysis （spa） . Results： MRSA isolated were SCCmec Ⅱ, Ⅲ type mainly by SCCmec typing, accounted for 50% and 46.4 % each; MRSA isolated were SCCmec Ⅱ , Ⅲ type mainly by spa typing, accounted for 41% and 35.1% each. Conclusion： MRSA isolates was mainly SCCmec m - to30 and SCCmec Ⅱ - t002 in Ordos.
