广西百色水利枢纽库区鼠疫自然疫源地调查研究

Investigation on the plague foci in Baise reservoir region in Guangxi province

目的查明百色水利枢纽库区沿岸鼠疫主要宿主动物和跳蚤的种类构成,了解该地区鼠疫疫源情况,为预防控制鼠疫提供科学依据。方法运用流行病学方法对库区的6个乡镇12个村屯展开调查,采集啮齿动物、指示动物和媒介蚤标本,分离鼠疫杆菌和检测鼠疫F1抗体。结果该地区啮齿动物有2目3科8种,以褐家鼠为优势鼠种;蚤类有3种,以印鼠客蚤为优势蚤种,所有标本检测结果均为阴性。结论百色水利枢纽库区沿岸具备形成家鼠鼠疫自然疫源地的条件,开展鼠疫监测和灭鼠灭蚤是预防控制鼠疫的重要措施。

Objective To find out the main plague reservoirs and vectors,and plague status in Baise reservoir region in Guangxi province and provide scientific guidance for plague prevention and control. Methods The investigations were carried out in 12 villages of 6 townships in this area with epidemiological methods. Rodents fleas and plague indicative animals were collected for isolating Yersinia pestis and detecting of F1 antibody . Results The 8 species in 3 families of the 2 orders of the rodents and the 3 species of fleas were identified in the areas. Rattus norvegicus and Xenopsylla cheopis were the dominant species. None samples was confirmed as infected by plague. Conclusion The study shows that Baise reservoir region is in compliance with the same conditions for rattus plague foci. Surveillance and killing rodents and vectors should be the important strategies for the plague prevention and control.
