摘　　要：目的了解北京市门头沟区自然环境中小型兽类群落构成及其密度,并检测是否存在鼠疫耶尔森菌(鼠疫菌)感染。方法 2009-2011年采用夹夜法捕捉小型兽类,鉴定鼠种并计算捕获率;用笼捕法捕捉活鼠,取心脏血进行鼠疫F1抗体检测。结果 2009-2011年在门头沟区捕获小型兽类7种315只,其中啮齿目6种309只,食虫目1种6只,小型兽类捕获率分别为16.60%、4.62%和15.08%;大林姬鼠、北社鼠和黑线姬鼠的捕获率和构成比最高,3种鼠合计占捕获总数的95.18%、88.89%和96.84%。鼠疫菌F1抗体血清学检测标本49份,结果均为阴性。结论北京市门头沟区鼠类血清学检测结果暂未发现鼠疫菌感染,不存在鼠疫自然疫源地。Objective To investigate the community structure and density of small mammals in the natural environment in Mentougou district of Beijing, China and to detect the infection with Yersinia pestis in the mammals. Methods The surveillance was conducted from 2009 to 2011. Small mammals were captured by trap at night method. The rodent species were identified, and the capture rate was calculated. Living rodents were captured by cage trap method, and blood samples were collected from the heart for detection of F1 antibody of Y. pestis. Results A total of 315 small mammals （7 species） were captured in Mentougou district from 2009 to 2011, including 309 mammals （6 species） of the order Rodentia and 6 mammals （1 species） of the order Insectivora. The capture rates of small mammals were 16.60%, 4.62%, and 15.08%, respectively for different year. The three species of rodents with the highest capture rate and constituent ratio were Apodemus peninsulae, Niviventer confucianus, and A. agrarius; the total proportions of the three rodents were 95.18%, 88.89%, and 96.84% from 2009 to 2011. In the serological detection, no Y. pestis F1 antibody was found in 49 blood samples. Conclusion No infection of Y. pestis has been found by serological detection in rodents in Mentougou district of Beijing, and there is no natural foci of plague in this area.
