动物生态学在大兴安岭流行性出血热宿主动物研究中的重要作用

Importance of Animal Ecological Study in the Research of Host Animals for the Epidemic Hemorrhagic Fever in Great Xingan Mountains.

在流行病的三大流行环节中,病原的宿主与疾病的传播媒介常是动物。动物学研究,尤其是动物生态学研究,常能在病原体尚未分离出来的情况下,判别出自然疫源性疾病的宿主动物,找出最主要的传播途径。

Epidemic hemorrhagic fever was first discovered in 1950s in the Great Xingan Mountains.Based on animal eeologlcal study and epidemiological analysis,it is determined that stripedfield mouse(Apodemus agrarius Pallas)is the host for the disease,which severely competewith house mice species.Striped field mouse inhabits mostly in residential areas and mig-rates seasonally.After extensive killing of the striped field mouse,the disease has been ef-fectively controlled since 1960.But in Chaocha forestry farm and Daomuda region,there stillexists natural sources of disease,which reqiures attention from different levels.
