1969年在灵武县首次分离出鼠疫菌后,证实了宁夏长爪沙土鼠鼠疫自然疫源地,该疫源地动物鼠疫“静息”10年后再次暴发流行。本实验采用分子生物学质粒图谱分析方法,对宁夏沙土鼠疫源地鼠疫菌的流行特性进行比较,现将历年来分离的鼠疫菌毒力及相关质粒报道如下。
After the first outbreak of Yersinia pestis in Lingwu County in 1969, it confirmed the natural foci of plague in Ningxia clawed gecko and the outbreak of animal plague reappeared again 10 years later. In this experiment, molecular epidemiology was used to compare the epidemiological characteristics of Y. pestis in Ningxia germplasm resources. The virulence of Yersinia pestis isolates and related plasmids were reported as follows.
