自然疫源地中鼠疫耶尔森氏菌的保存问题

Persistence of Yersinia pestis strains in plague natural foci

鼠疫的发生得益于鼠疫菌能够在自然界长期存在。无论是鼠疫流行期还是间歇期,鼠疫菌在自然界中究竟存在于何地,以何种方式保存,又以什么机制造成流行是鼠疫发生的神秘之处。因此,研究鼠疫菌在自然疫源地各生态要素中的保存状况及生存能力,有助于揭示鼠疫的发生及传播规律。

The plague occurs due to the long-term persistence of Yersinia pestis in natural environment.During the period of plague epidemic and quiescence,there are still some unknown scientific questions,such as where Yersinia pestis preserved,which mode preserved,and which mechanism caused plague epidemic.Thus,the researches on the preservation and viability of Yersinia pestis in every ecological element of plague natural foci will contribute to find the pattern for the occurrence and spread of plague.
