摘要: 目的 分析医院不同科室来源的耐甲氧西林金黄色葡萄球菌(MRSA)菌株基因分型同源性,为控制MRSA医院感染流行提供科学依据。 方法 使用细菌基因组重复序列聚合酶链反应(REP-PCR)以及高级微生物基因分型系统(DiversiLab)细菌同源性分析技术对23株医院感染的MRSA进行基因分型。 结果 23株MRSA分为4个基因型,A型、D型主要分布于急诊观察室,B型、C型主要分布于中医外科。 结论 中医外科存在以B型、C型基因型为流行株的MRSA医院感染爆发;REP-PCR技术和DiversiLab自动化细菌同源性分型技术可成为医院感染病原研究的有效手段。

Abstract: Objective To provide scientific referencefor controlling hospital acquired infection through analyzing the genotype homology of methicillin resistant Staphylococcus aureus(MRSA) which were isolated from different departments of hospital.   Methods The genotypes of 23 strains of hospital acquired MRSA were analyzed by repetitive polymerase chain reaction(REP-PCR) and DiversiLab genotype system. Results Hospital acquired MRSA were classified into 4 kinds of genotypes(A,B,C and D).A and D types were mainly distributed in Emergency Observation Room,while B and C types were mainly distributed in Traditional Chinese Medicine Surgery Department. Conclusions B and C types may cause infection outbreak in Traditional Chinese Medicine Surgery Department as epidemic strains. REP-PCR and DiversiLab genotype system can be efficient ways for research of pathogen on nosocomial infection.
