目的探讨宁夏回族自治区灵武市生态工程建设对鼠疫自然疫源地的影响。方法采取0.5%分层抽样法监测鼠密度,鼠疫病原学的分离采取鼠类病变脏器及组织压印培养的方法,蚤的细菌学检验采取集组及拉胃培养的方法。结果 2006～2010年共捕获野鼠1 406只,隶属5科7属13种;该疫源地以长爪沙鼠和子午沙鼠为优势种,黄鼠、三趾跳鼠、五趾跳鼠、灰仓鼠和黑线仓鼠为常见种,小毛足鼠、大仓鼠和东方田鼠为稀有种。结论宁夏灵武市实施的生态工程、自然保护区及禁牧,短期内增加了鼠害及动物鼠疫爆发的频度和危险。
Objective To explore the impact of ecological construction in Lingwu City of Ningxia Hui Autonomous Region on the natural foci of plague. Methods The rat density was monitored by 0.5% stratified sampling method. The etiology of plague was separated from the diseased organs of mice and imprinting culture. The bacteriological test of fleas was performed by the method of grouping and pulling the stomach. Results A total of 1 406 wild voles were captured from 2006 to 2010, belonging to 13 species of 5 genera and 7 genera. The dominant species were Meriones unguiculatus and Meriones unguiculatus, Gray hamsters and black hamsters are common species, small hamster, big hamster, and eastern vole for rare species. Conclusion Ecological engineering, nature reserves and no-grazing in Lingwu City, Ningxia Province increase the frequency and danger of the outbreak of rat and animal plague in the short term.
