摘要
目的调查攀枝花市是否存在鼠疫自然疫源地。方法 2013-2014年结合鼠疫监测工作,在攀枝花市西区的格里坪镇和仁和区福田镇采集犬血清,对捕获鼠类采集肝脏和脾脏组织及其体表寄生蚤,检测鼠疫菌和鼠疫抗体,统计分析动物分布情况和检测结果。结果 2013-2014年鼠疫宿主动物调查室内布放鼠笼1106个,捕获鼠类62只(褐家鼠39只、小家鼠23只),密度为5.61%,野外布放鼠夹898夹,捕获褐家鼠5只,密度为0.56%;鼠体染蚤率为7.46%,蚤指数为0.18;鼠血清检测均为阴性。采集犬血清204份,鼠疫F1抗体阳性9份,阳性率为4.41%。结论攀枝花市存在鼠疫自然疫源地可能性大,应加强鼠疫监测,积极开展疫源地的调查研究工作。
Objective We surveyed whether the plague natural foci exists in Panzhihua city. Methods From 2013 to 2014, we detected the F1 antibody of serums which came from dogs of Geliping and Futian in the plague monitoring of Panzbihua. All of the rats trapped by the way of squirrel-cage and rat-clip. The livers, spleens and fleas came from trapped rats were used for species identification and bacterial culture. Results From 2013 to 2014, 62 rats （39 Rattus norvegicus rats and 23 Mus musculus rats） were trapped by 1106 squirrel-cages in home, and 5 R. norvegicus rats captured by 898 rat-clips in field. The rat density in home is 5.61%, and in field is 0.56%. We gained 12 fleas from 5 in 67 rats, and the sampled rats belonged to 1 species, 1 genera and 2 families. The flea infected rate is 7.46%, and flea index is 0.18, and serum positive rate of rats is 4.41%. Conclusion The plague natural foci may exist in Panzhihua city and more attention should be take to monitoring plague epidemiology.
