Abstract:
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 rodents 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.
