Abstract

The role of fleas in the manifestations of plague epizootics in the natural plague foci in Russia and adjacent states is discussed. The specific conditions of pathogen transmission in each focus are determined by the vital activities of several species of fleas that are parasites of the main plague carrier. These fleas have the nidicolous type of parasitism, facilitating wide spread of the plague microbe in the focus. Most of the natural plague foci include more than one vector species. The most intense epizootic outbreaks in each focus occur during the periods of active feeding and reproduction of the flea vectors.

跳蚤（Siphonaptera）在自然瘟疫疫源地中的意义

摘要

讨论了跳蚤在俄罗斯和邻近国家的自然鼠疫疫源地鼠疫流行中的作用。在每个焦点上病原体传播的具体条件取决于作为主要鼠疫携带者的几种跳蚤的生命活动。这些跳蚤具有寄生性的荒谬性，促进了鼠疫微生物在重点地区的广泛传播。大多数天然鼠疫病灶包括一种以上的媒介物种。在每个跳蚤载体的主动饲养和繁殖期间，每个病灶中最强烈的流行病暴发发生。
