| 摘 要： | 宁夏阿拉善黄鼠疫源地鼠疫菌株有两个稳定的遗传型,即Leu~- Phe~- Ala~-和Leu~+ Phe~+Ala~+。两者均具有完全毒力,在动物鼠疫流行中均可分离到,都适于阿拉善黄鼠体内寄生和循环。但Leu~+型菌株对阿拉善黄鼠有更强的适应性和选择性。

| Abstract: | There were 2 stable genotypes of Y.pestis characterized by Leu- Phe- Ala-and Leu+ Phe+ Ala+ in the natrual foci of Citellus dauricus alaschanicus plague in Ningxia, both of them showed complete virulence, and suitable for parasi-ting and circulating in Citellus dauricus alaschanicus. The Leu+ strains, however, were more adaptive and selective to Citellus dauricus alaschanicus than the other strains. |
