摘　　要：目的调查北京市怀柔区啮齿动物及其寄生蚤种群组成及数量动态，开展动物鼠疫血清学监测。方法2009—2011年，在怀柔区8个乡镇的不同生境中进行啮齿动物密度调查，采集啮齿动物血清进行鼠疫间接血凝试验，对寄生蚤进行分类鉴定。结果共捕获啮齿类动物8种709只，鼠密度为2．52％（83／3300），社鼠、大林姬鼠为优势鼠种，分别占捕鼠总数的46．4％（329／709）、18．1％（128／709）；采集啮齿动物血清563份，鼠疫血清F1抗体检测均为阴性；检蚤200匹，染蚤率29．63％（48／162），蚤指数1．23，屈褶副角蚤、多刺细蚤为优势蚤种．分别为30、27匹。结论目前尚无动物鼠疫流行的迹象，但仍存在着适宜啮齿类动物生存的环境条件。Objective To investigate the species composition and quantitative dynamic state of rodent and parasitic flea in Huairou District of Beijing City, and to carry out serologic monitoring of animal plague. Methods Rodent density was investigated at different habitats in eight villages and towns between 2009 and 2011. Serum samples from captured rodents were detected by indirect hemagglutination test, and genotypes of collected parasitic fleas were identified. Results A total of 709 ~odents which belong to eight different kinds were captured with a rodent density of 2.52% （83/3 300）, and Rattus niviventer and Apodemus peninsulae were dominant species, acounted for 46.4% （329/709） and 18.1% （128/709）, respctively. Five hundred and sixty-three serum samples of rodents were tested by plague indirect hemagglutination, and all of them were plague antibody negative. Two hundred fleas were checked with a flea infected rate of 29.63% （48/162）, and a flea index of 1.23; Paraceras crispus and Leptopsylla pavlovskii were dominant flea species, a total of 30 and 27, respectively. Conclusion Some environment conditions are suitable for rodents survival, even though there is no sign of animal plague epidemic.
