摘要: 目的 探讨我国不同地域红色毛癣菌分离株的遗传多样性。方法 采用随机扩增DNA多态性(RAPD)方法对来源于我国不同地域(江苏南京,山东济南,广东广州)的32株红色毛癣菌临床分离株进行DNA多态性分析。结果 红色毛癣菌种内差异明显,根据遗传相似性分成三大聚类群,与地域差异及取材部位无明显相关性,而与表型具有一定相关性。结论 随机扩增DNA多态性方法可用于红色毛癣菌的DNA分型,其DNA带型具有一定的遗传变异性,与菌株表型有一定关系,与地域差异、侵犯部位无明显相关性。

Abstract: Objective To study the genetic diversity of T.rubrum from different geographical origins of China(Nanking,Jinan,Guangzhou).Methods Totally 32 clinical isolates of T.rubrum were collected and analyzed by random amplified polymorphic DNA(RAPD)analysis.Results Subsequent analysis of the gel profiles by computerized cluster-derived dendrograms revealed that significant intraspecific differences were relevant to phenotype,but not the region or isolated sources which divided Trichophyton rubrum into 3 cluster groups.Conclusions RAPD assay is useful for molecular typing of T.rubrum.

Key words: Trichophyton rubrum, genetic diversity, random amplified polymorphic DNA method
