[目的]分析广东省鼠疫原疫区鼠形动物、媒介的种类及密度的现状,为制定鼠疫的防控策略提供依据。[方法]采用笼捕法在广东25个鼠疫原疫区(市、县、区)捕鼠和检查蚤,进行分类鉴定和计算统计。[结果]广东省2005～2008年共捕获鼠形动物2目2科(亚科)4属11种,其中居民区主要有褐家鼠、黄胸鼠、臭鼩鼱,野外区主要有黄毛鼠和板齿鼠,居民区和野外的平均捕获率分别为7.76%和3.16%。发现蚤类8种,平均鼠体染蚤率为33.60%,总蚤指数为1.02。[结论]初步澄清近几年广东省鼠疫原疫区的宿主和媒介种类。并显示结构维持稳定,密度较低。应继续坚持监测工作,防止鼠疫复燃。
[Objective] The research aimed to analyze the current situation of the species and density of mouse-type animals and vectors in the plague-endemic area of Guangdong Province, and provide evidence for the prevention and control of plague. [Method] The method of cage catching was used to catch the rat and check the fleas in 25 epidemic plague areas (cities, counties and districts) in Guangdong Province for classification, identification and calculation. [Result] A total of 11 species of 4 genera of 2 families (subfamilies) were captured in Guangdong Province from 2005 to 2008. Among them, Rattus norvegicus, Rattus flavipectus, The average catch rates in rats and plateau rats, residential areas and in the wild were 7.76% and 3.16% respectively. Eight species of fleas were found, with an average flea flea rate of 33.60% and a total flea index of 1.02. [Conclusion] The preliminary clarification of host and vector types of plague origin in Guangdong Province in recent years. And showed that the structure remained stable with low density. Monitoring work should continue to prevent the plague from rekindle.
