Abstract: At the initial stage of epidemics, the bacteria of plague natural foci were more virulent, nitrogen removal was stable, and the plasmid species were relatively complete and stable. But at the end of the epidemic, the virulence of the plague was weaker, nitrogen removal was not stable, and plasmids tended to be absent. There were great differences in the morphology of plague bacteria in nature. Biological, biochemical, plasmid and virulence of Yersinia pestis were investigated in Hebei province, China. The mechanism of the existence of plague was revealed in some way.

Key words: Yersinia pestis, Variability, Hebei province

摘要: 在河北省鼠疫自然疫源地流行初期分离的鼠疫耶尔森菌(鼠疫菌)毒力较强,脱氮能力稳定,质粒种类丰富,但在流行末期分离的鼠疫菌往往毒力较弱,脱氮能力不稳定,质粒易缺失。鼠疫菌的形态学在自然界中存在较大差异。该文通过探讨河北省鼠疫菌的生物学、生化、质粒和毒力变异情况,揭示鼠疫静息期存在的机制。
