摘　　要：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 For studing the composition and distribution of the host animails of plague in Guangzhou city.Method Rodents were captured by cages and identified species,counted flea index and tested for antibody of plague F1 by IHA. Results 1 308 rodents, including 1 212 rattus and 96 insectivora were caught, which were belonged to 9 species, 4 genera, and 2 families. Total density of rodents and density of rattus was 10.83% and 10.03%, respectively. 112 fleas were caught and belonged to Xenopsylla cheopis from 46 rattus among 143 rodents. The total flea index was 0.78. No F1 antibody of plague was found. Conclusions The major rodent species and the dominant species in Guangzhou city was Rattus norvegicus and Xenopsylla cheopis, respectively. No epidemiological evidence of plague is found.
