【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。方法采用夜笼法捕鼠,并对鼠类及捡获蚤类进行鉴定,计算鼠染蚤率和蚤指数。用鼠疫IHA法检测鼠疫F1抗体。结果捕获鼠形动物2259只,分属2目2科3属7种。其中啮齿目动物2014只,食虫目动物245只,总鼠密度为12.09%,鼠密度为10.78%。在559只鼠形动物中发现有蚤鼠只73只,捡获蚤297匹,鼠体表蚤经鉴定为印鼠客蚤,鼠染蚤率为13.05%,总蚤指数为0.53,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。更多还原

【Abstract】 Objective To examine the composition and distribution of animal reservoir of plague in Guangzhou city. Method Rodents were captured by cages and then identified. Flea index was determined and plague IHA method was used to test for antibody. Result 2259 rodents (including 2014 rattus and 245 insectivora) were caught and identified. The animals were grouped into 7 species, 3 genera, and 2 families. Total density of rodents and rattus was 12.09% and 10.78%, respectively. A total number of 297 fleas, belonging to the species of Xenopsylla cheopis, were caught from 73 rattus. The total flea index was 0.53. No F1 antibody was found. Conclusion The major rodent species found in Guangzhou city is Rattus norvegicus. And Xenopsylla cheopis is the dominant species of flea in these animals. Spreading of plague among rattus was not found.更多还原
