摘要
目的了解广州市鼠疫宿主动物的种群构成及数量分布情况,为鼠疫防治工作积累基础资料。方法采用夜笼法。对捕获鼠类及检获蚤类进行鉴定;计算鼠带(染)蚤率和蚤指数;用鼠疫IHA法检测鼠疫FI抗体。结果捕获鼠形动物1709只,分属2目2科4属7种。其中啮齿目动物1615只,食虫目动物94只,总鼠密度(捕获率)为10.39%,鼠密度(捕获率)为9.83%;在194只鼠形动物中发现染蚤鼠40只,检获蚤84只,鼠体表蚤经鉴定为印鼠客蚤、猫栉首蚤;鼠染蚤率为20.62%,总蚤指数为0.43;黄胸鼠蚤指数为0.56;未查出鼠疫FI抗体。结论褐家鼠仍是广州市主要鼠种,主要蚤种是印鼠客蚤,未发现鼠间鼠疫流行迹象。
Objectives For studing composition and distribution of the host animails of plague in Guangzhnu city. Methods Rodents were captured by cages and identified species, counted flea index and tested antibody of plague FI by IHA. Results 1709 rodents, including 1615 rattus and 94 Insectivora, were caught, which were belonged to 7 species, 4 genera , 2 family. Total density of rodents and density of rattus was 10.39% and 9.83% , respectively. 84 fleas were caught and belonged to Xenopsylla cheopis from 40 rattus among 194rodents. The total flea index was 0.43. No FI antibody of plague was found. Conclusions The major rodent species and the dominant species in Guangzhou city was Rattus norvegicus and Xenopsylla cheopis, respectively.
