| 摘 要： | 目的建立PCR—RAPD反应体系,提升细粒棘球蚴随机扩增多态性DNA（RAPD）遗传多态性研究的稳定性,为研究细粒棘球蚴的分类学以及包虫病的分子流行病学奠定基础。方法采用改进的酚-氯仿抽提法提取细粒棘球蚴基因组DNA,用单因素筛选方法建立PCR—RAPD分析体系。结果采用改进的酚／氯仿抽提方法提取细粒棘球蚴基因组DNA质量高,适用于PCR—RAPD扩增分析;在25μL体系中,RAPD—PCR扩增反应各成分的最佳浓度为：dNTP0．2—0．3mmol／L、Taq酶2．5U、随机引物0．8—1．4μmol／L,模板为60ng。PCR扩增最佳条件为：95℃预变性5min;94℃变性30s、32℃退火45s、72℃延伸1min、共35个循环;最后72℃延伸10min;初步从20条引物中筛选出11条带型丰富的随机引物。结论酚-氯仿适用于提取细粒棘球蚴基因组DNA,优化的RAPD反应体系和筛选出的随机引物适合进行细粒棘球蚴RAPD遗传多态性分析。
