摘要
目的分析甘肃祁连山-阿尔金山旱獭疫源地动物鼠疫流行规律,评估其危害性,为制定鼠疫防控对策提供科学依据。方法采用描述性流行病学方法对甘肃祁连山-阿尔金山旱獭疫源地的鼠疫监测报告、鼠疫自然疫源地调查资料、鼠疫信息库数据库的数据进行分析。结果1980-2018年间,疫源地内旱獭数量在0.12-2.74只/hm^2范围变动,总平均密度0.69只/hm^2;共布鼠夹(笼)264918个,捕获9750只,平均捕获率为3.68%。捕获啮齿动物分别属于2目6科14属20种,其中小家鼠、灰仓鼠、长尾仓鼠为优势种。1959-2018年间,疫源地内共分离鼠疫菌2082株,其中动物体内分离1388株,媒介分离692株,旱獭巢蚤土壤分离鼠疫菌2株。结论甘肃祁连山-阿尔金山草原喜马拉雅旱獭疫源地动物间鼠疫流行强度差别很大,一些地区动物鼠疫流行猛烈,一些地区则已静息多年,应针对不同流行态势采取不同的防控措施。
Objective To analyze the epidemiological characteristics of animal plague in alpine grassland marmot foci of Qilian mountain and Aerjin mountain of Gansu province,evaluate its harmfulness,and provide scientific basis for formulating plague prevention and control strategies.Methods Descriptive epidemiology was used to analyze the reports of plague surveillance,data from studies of natural plague foci,and data from plague information base database of Qilian mountain and Aerjin mountain in Gansu province.Results From 1980 to 2018,the number of marmots varied from 0.12 to 2.74 per hm^2,and the total average density was 0.69 per hm^2;A total of 264,918 rats were trapped in traps and 9,750 were caught,with an average catch rate of 3.68%.Captured rodents belong to 2 orders,6 families,14 genera and 20 species respectively.Among them,small house mouse,grey hamster and long-tailed hamster are dominant species.From 1959 to 2018,a total of 2082 strains of Yersinia pestis were isolated from infected animals,insects and vector materials in alpine grassland marmot foci of Qilian mountain and Aerjin mountain in Gansu province.Among them,1388 strains were isolated from the animal body,692 strains from insects,and 2 strains from the soil of marmot’s nest flea.Conclusion The foci was a large,distributed widely and discontinuously area,and the intensity of plague epidemics varies greatly among animals.In some areas,the epidemic of animal plague is severe,and in some areas,it has been quiet for many years.so we should take different measures to prevent and control the plague.
