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 understand the composition and density of small mammals in the natural environment in Mentougou District of Beijing and detect the presence of Yersinia pestis (Yersinia pestis) infection. Methods 2009 to 2011, small night beasts were captured by the method of catgut nocturnal, the species of the mice were identified and the catching rate was calculated. The living cats were captured by the cage catching method and the blood was taken for the detection of the F1 antibody. Results A total of 315 small mammals were collected from Mentougou District in 2009-2011, including 309 species of 6 species of 309 species of rodents and 6 species of 1 species of insects. The capture rates of small mammals were 16.60%, 4.62% and 15.08%, respectively. Apodemus, Apodemus and Apodemus had the highest capture rate and constituent ratio, accounting for 95.18%, 88.89% and 96.84% of the total number captured respectively. 49 strains of Y. pestis F1 antibody serological test results were negative. Conclusions The results of rat serological test in Mentougou District of Beijing suggest that no Yersinia pestis infection is found, and no natural epidemic area of plague exists.
