摘要
目的开展鼠疫疫源地调查,为三峡库区鼠疫防控提供依据。方法采用笼夜法捕鼠,对捕获鼠类及检获蚤类进行鉴定;计算鼠带蚤率和蚤指数。结果共捕获鼠195只,鼠密度为5.13%,其中室外鼠密度(6.98%)高于室内鼠密度(3.01%)(χ2=29.88,P<0.01)。检获蚤339匹,鼠染蚤率为39.50%,总蚤指数为1.74。结论三峡库区丰都县段未发现鼠疫疫情,黄胸鼠为主要鼠种,其携带蚤种主要为缓慢细蚤,且染蚤率及蚤指数较高,应引起重视。
Objective To provide the basis for prevention and control of plague in the Three Gorges Resevoir through monitoring of the host animals,insects and plagues.Methods The captured rodents by cages and collected fleas were identified,the rate of rodents with fleas and the flea index were calculated.Results 195 rodents were caught.Total density of rodents was 5.13%,the density outdoors was 6.98%,higher than that in indoors which was 3.01%（χ2=29.88,P0.01）.339 fleas were caught and the rate of rodents with fleas was 39.50%,the total flea index was 1.74.Conclusion No plague is found in the region of Fengdu County in Three Gorges Area.R.flavipectus is the dominant species,mainly carrying with high index of Leptopsylla segnis,which should be paid attention to.
