目的了解广西隆林县2000年家鼠型鼠疫暴发流行期蚤类的种群特征 ,分析疫情发生流行的影响因素。方法在鼠疫暴发流行期间对疫区及周围地区将捕获的黄胸鼠、小家鼠进行采集鼠体蚤类 ,计算鼠体蚤指数 ;采用粘蚤纸法粘捕室内游离蚤 ,计算游离蚤指数。结果调查的13个疫区村屯共捕获黄胸鼠14只,检获鼠体蚤44匹 ;而疫区周围的8个村屯共捕获黄胸鼠158只 ,检获鼠体蚤271匹 ,疫区黄胸鼠鼠体的印鼠客蚤指数、地面游离印鼠客蚤指数分别为3.14和0.033,明显高于疫区周围村屯。结论鼠疫流行期主要传播媒介为印鼠客蚤。疫区与非疫区的小家鼠鼠体染蚤率较低 ,显示小家鼠鼠体蚤种群未对疫情流行产生直接影响
Objective To understand the population characteristics of fleas in the epidemic period of house mouse type plague in 2000 in Longlin County, Guangxi and analyze the influencing factors of epidemic situation. Methods During the epidemic of plague, Rattus flavii and Mus musculus were collected from the affected area and the surrounding area to collect the flea index of the rats. The free flea index . Results A total of 14 Rattus flavescens were caught and 44 rodents were seized in 13 outbreak-affected villages. In the 8 villages around the affected area, 158 Rattus flavescens were captured and 271 rodents were seized, The rat-flea index and rat-free flea index of littoral rats were 3.14 and 0.033, respectively, which were significantly higher than those of the surrounding villages. Conclusion The main transmission medium during the plague epidemic is the rat and rat fleas. The rate of flea flea infection in the diseased and pest free areas was low, indicating that the flea flea population did not have a direct impact on the epidemic
