目的探讨自毙鼠在长爪沙鼠鼠疫自然疫源地监测中的作用,为动物间鼠疫监测及预警提供指导。方法收集整理宁夏回族自治区2001-2010年长爪沙鼠鼠疫疫源地各县(区)监测点的数据和资料。夜行鼠调查采用5 m夹线法,长爪沙鼠调查采用坑式布夹法。结果 2001-2010年共捕获野鼠8675只,隶属5科7属15种,以长爪沙鼠和子午沙鼠为优势种群。10年来动物间鼠疫共发生4年次流行,其中自毙鼠检菌阳性率高达61.54%,捕获鼠检菌率为2.31/万,建立了宁夏2001-2010年沙鼠鼠疫疫源地基础信息数据库。结论自毙鼠在沙鼠鼠疫疫源地的发现,是动物鼠疫流行的早期迹象。
Objective To explore the role of Zizhu mice in the monitoring of natural foci of gecko plague and provide guidance for the monitoring and early warning of plague in animals. Methods The data and data of monitoring points of counties (districts) in the Epidemic of Meriones unguiculatus from 2001 to 2010 in Ningxia Hui Autonomous Region were collected and sorted. Night rat survey using 5 m line method, Mongolian gerbil investigation using pit cloth clamp method. Results A total of 8675 wild cats were collected from 2001 to 2010, belonging to 15 genera and 7 genera in 5 families. Meriones unguiculatus and Meriones unguiculatus were dominant populations. In the past 10 years, the prevalence of plague in animals has been prevailing for 4 years. The positive rate of self-killed mice was 61.54%, and the rate of capturing mice was 2.31 per 10,000. The basic information database of gerbil plague origin in Ningxia from 2001 to 2010 was established . Conclusions The discovery of Zizhu mice in the plague foci of gerbil is an early sign of the epidemic of animal plague.
