目的了解广州市鼠疫宿主动物及其媒介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。方法采用夜笼法捕鼠,对捕获鼠类及捡获蚤类进行鉴定,计算鼠密度;计算鼠带(染)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1308只,分属2目2科4属9种。其中啮齿目动物1212只,食虫目动物96只,总鼠密度(捕获率)为10.83%,鼠密度(捕获率)为10.03%;在143只鼠形动物中发现染蚤鼠46只,捡获蚤112匹,鼠体表蚤经鉴定均为印鼠客蚤;鼠染蚤率为32.17%,总蚤指数为0.78;黄胸鼠蚤指数为0.59;未查出鼠疫F1抗体。结论未发现鼠间鼠疫流行迹象;褐家鼠仍是广州市主要鼠种;主要蚤种是印鼠客蚤。
Objective To understand the population composition and population distribution of plague host animals and their vectors in Guangzhou and to accumulate basic data for prevention and control of plague. Methods The rat was captured by the night cage method, and the rodents were captured and the fleas were collected for identification. The density of the rodents was calculated. The flea rate and the flea index were calculated. The F1 antibody against the plague was detected by the plague IHA method. The results captured 1308 mouse-shaped animals, belonging to 2 orders, 2 families, 4 genera and 9 species. Among them, 1212 rodents and 96 carnivores, the total rodent density (catching rate) was 10.83% and the rat density (catching rate) was 10.03%; 46 of them were found in 143 mouse-shaped animals, picking up Fleas were 112 horses, fleas were identified on the rat were printed rat flea; rat flea flea rate was 32.17%, total flea index of 0.78; flea index was 0.59; did not detect the plague F1 antibody. Conclusion No epidemic signs of plague in rats were found. Rattus norvegicus was still the main rat in Guangzhou.
