摘要
目的研究内蒙古4型疫源地蚤类中自然染疫蚤的种类,分析该地区蚤类的鼠疫流行病学意义。方法收集整理历年鼠疫自然疫源地流行病学调查和检测中检出鼠疫菌的蚤种种名和检出地点。结果内蒙古发现的122种(亚种)蚤类中,从30种(亚种)蚤体中检出鼠疫菌。结论 4型疫源地中3个疫源地的主要媒介蚤种都可自然感染鼠疫菌,几乎所有次要媒介蚤中都检出鼠疫菌。
Objective To determine the species of fleas infected with Yersinia pestis in the plague foci in Inner Mongolia and analyze the role of fleas in the epidemiology of plague. Methods Data on the species and location of infected fleas in this area were collected from the epidemiological surveillance in past years. Results Y. pestis were found from 30 out of 122 subspecies in Inner Mongolia. Conclusion The major vector fleas from three of the four foci in this area are able to carry the infection, and almost all minor fleas have been infected.
