许多学者都曾述及,废弃的鼠、獭洞穴内的“疫蚤”可以起到保存鼠疫菌的作用,在疫源地的维持上占有一定的地位。我们所做蚤保菌越冬试验表明,鼠疫菌可以寄生于方形黄鼠蚤阿尔泰亚种等蚤种越过长尾黄鼠的冬眠期,从而证实跳蚤可以起到一定的贮存宿主作用。那么,在漫长的非冬眠期中,在废弃鼠洞存活的感染蚤亦即在长期不给感染的跳蚤供血的情况下,他们的命运如何呢?为此,我们按传统的方法将吸血感染的
Many scholars have already mentioned that the “fleas” in abandoned mounds and otters can play a role in preserving Yersinia pestis and occupy a certain place in the maintenance of foci. We have done fleas overwintering bacteria test shows that Y. pestis can parasitize the square-shaped rat fleas Altai and other fleas over the horsetail long-squirrel dormancy period, which confirmed that fleas can play some storage host role. So, in the long period of non-hibernation, in the abandoned mouse hole in the survival of infected fleas, that is, in the long-term does not give infected fleas in the case of their fate? To this end, we traditionally vampire-infected
