摘要
目的 :研究 115株鼠疫菌的生物学特性及与鼠疫动物病流行的关系。方法 :生化试验及毒力决定因子测定。结果 :由于鼠疫自然疫源地的不同 ,所分离的鼠疫菌株在表型特征方面存在着相对稳定性的差别。结论 :按中国鼠疫菌的生态分型标准 。
Objective:To research on the biological and epidemiological characteristics of 115 Y.pestis. Methods:Detection of virulent factors.etc.Result:Isolated from different foci and reservoirs in Northern Hebei and in middle Inner Mongolia, 115 strains of Y.pestis have been performed with permentation of alcohol and carbohydrate,nitrate reduction,urea decomposition,indigo formution and virulent factors etc. Conclusion:The results have showed differences of relative stability brom phenotypic charactors because of different natural foci. According to Chinese Y.pestis ecotype,they belong to Erduosi Plateau.
