鼠疫菌在疫源地保存机制的研究进展

摘要

在鼠疫自然疫源地中,鼠疫菌与其宿主动物和媒介生物在一定地理景观内以及特定区域的生物群落中构成了相互依赖又相互制约的生态系统.目前,鼠疫菌的保存机制主要概况为:①宿主动物、蚤(蜱等)保存学说;②鼠疫菌自身突变保存学说;③蚤-宿主-蚤保存学说;④土壤保存学说;⑤鸟类及非生物因素保存学说;⑥其他耶尔森菌突变保存学说.文中针对鼠疫菌在疫源地保存机制的研究进展做以下综述.%Yersinia pestis,host animals and vector organisms in a particular area within a certain geographical landscape,and biological communities are in the form of interdependence and mutual restriction of ecological system in the plague natural foci of plague.Currently,the preservation of Yersinia pestis mechanism mainly including:①Animal and fleas (tick) preservation theory;②Yersinia pestis own mutation preservation theory;③Fleas-host-fleas preservation theory;④Theory of soil preservation;⑤the birds and abiotic factors of preservation theory;⑥Theory of other Yersinia preservation theory and so on.The author summarized the research progress of the preservation mechanism of Yersinia pestis in the focus area.
