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。对捕获鼠类及捡获蚤类进行鉴定;计算鼠带蚤率和蚤指数;用鼠疫IHA法检测鼠疫F1抗体。结果捕获鼠形动物1636只,分属2目2科3属6种。其中啮齿目动物1399只,食虫目动物237只,总鼠密度为12.63%,鼠密度为10.80%;在250只鼠形动物中发现有蚤鼠85只,捡获蚤407匹,鼠体表蚤经鉴定为印鼠客蚤、缓慢细蚤;鼠染蚤率为34.0%,总蚤指数为1.63;黄胸鼠蚤指数为2.36;未查出鼠疫F1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。黄胸鼠蚤指数较高,应引起重视。
Objective This study was conducted to understand the structure and distribution of animal species for plague host animals in Guangzhou Province, and so as to accumulate basic data for plague prevention and control, Methods A method of Yelong was adopted. The captured rats and collected fleas were identified, the rate of rats with fleas and the flea index were calculated, and the plague F1 antibody was tested with IHA method for plague. Results There were 1636 captured animals of rat shape, which were divided into 2 orders, 2 families, 3 genera, and 6 strains, including 1399 rodents and 237 animals of inseetiviora, with total rat density of 12.63% and rat density of 10.80%. Among 250 animals of rat shape, there were 85 flea rats found with collected 407 fleas. The fleas on surface of rat were identified as xenopsylla cheopis and leptopsylla segnis, and flea infection rate of rats was 34.0%, with total flea index of 1.63, and rattus flavipectus flea index 2.36. F1 antibody to the plague was not found. Conclusion Sewer rat was still the main species of rat in Guangzhou City. The main flea was xenopsylla cheopis. No sign of plague prevalence among rats was found. The flea index of rattus flavipetus was relative high, which should be attached importance.
