目的了解厦门市鼠疫宿主动物及其寄生蚤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。方法采用笼捕法。对捕获鼠类及检获蚤类进行鉴定,计算鼠带蚤率和蚤指数,用IHA法检测鼠疫F1抗体。用RIHA法检测鼠疫F1抗原。结果捕获鼠形动物481只,分属2目2科3属5种。其中啮齿目动物428只,食虫目动物53只,家栖鼠密度为5.07%,黄胸鼠密度为1.00%,野栖鼠密度为4.57%。发现蚤类4种,主要蚤种为印鼠客蚤,平均鼠染蚤率为2.22%,总蚤指数为0.01。未查出鼠疫F1抗体和抗原。结论褐家鼠仍是厦门市主要鼠种,主要蚤种是印鼠客蚤,未发现鼠间鼠疫流行现象,局部黄胸鼠密度较高,应引起重视。
Objective To understand the population composition and quantity distribution of plague host parasites and parasites in Xiamen and to accumulate basic data for the prevention and control of plague. Methods cage catching method. The capture of rodents and detection of fleas were identified, the rate of flea infection and flea index was calculated, and the IHA method was used to test the F1 antibody against plague. Detection of Plague F1 Antigen by RIHA Method. Results 481 mouse-shaped animals were captured, belonging to 2 orders, 2 families, 3 genera and 5 species. Among them, 428 were rodents, 53 were carnivores, the density of domestic animals was 5.07%, the density of yellow rat was 1.00% and the density of wild rats was 4.57%. Four species of fleas were found. The main flea species were fleas, with an average of 2.22% flea and flea index of 0.01. No plague F1 antibodies and antigens were detected. Conclusion Rattus norvegicus is still the main species in Xiamen City. The main flea species are the rat fleas, but the epidemic phenomenon of plague in rats is not found. The density of Rattus flavipectus is high, which should be paid more attention.
