摘要
目的 了解不同地区田鼠型鼠疫耶尔森氏菌 (以下简称鼠疫菌 )之间的亲缘关系和基因类型。方法 随机扩增多态性DNA(RAPD)技术。结果 扩增的 13株田鼠型鼠疫耶尔森氏菌在凝胶电泳所显示的条带 ,除 3株菌缺少部分条带外 ,其余菌株基本相同。结论 青海田鼠型鼠疫耶尔森氏菌和布氏田鼠型鼠疫耶尔森氏菌具有相似性 ,在遗传学上属于同源。
To study the relationship,and the gene types among Yersinia pestis strains of Microtus type from different areas Random amplified polymorphism DNA (RAPD) were used.Amplified products of 16 Y.pestis strains of Microtus type by gel electrophoresis method showed that stripes of 13 strains were same, but 3 strains were short of part stripes.It concludes that Y. pestis strains isolated from Microtus fucus and Microtus brandti are similar and belong to same origins on genetics.
