本文对宁夏不同地区,不同宿主分离的164株鼠疫杆菌进行了毒力和毒力因子的测定。结果表明,宁夏南部阿拉善黄鼠疫源地和东北部长爪沙鼠疫源地的试验菌株,均属强毒杆菌,而阿拉善黄鼠疫源地菌株的毒力较强,因此鼠疫杆菌F_1,PSTI毒力因子作为鼠疫杆菌的诊断是可行的,通过测定,对疫源地的鉴定,鼠疫菌的分型,毒力株和弱毒株相互关系以及流行情况都有较清楚的认识。
In this paper, 164 strains of Yersinia pestis isolated from different hosts and different hosts in Ningxia were tested for their virulence and virulence factors. The results showed that all the tested strains of A. clarkii in the southern part of Ningxia and the northeastern part of the clawed plague were all virulent strains of toxins, Force factor as Yersinia pestis diagnosis is feasible, through the determination of the identification of foci, Yersinia pestis typing, virulence strains and attenuated strains of interrelationships and prevalence have a more clear understanding.
