流行性出血热病毒在宿主动物间传播方式及其流行病学意义的研究

Study on the Mode of Transmission of EHFV among Host Animals and Its Epidemioiogic Significance

应用血清学检测技术在驻地进行了流行性出血热病毒(EHFV)在宿主动物间传播方式及其流行病学意义的研究。结果表明在自然条件下主要宿主间存在水平传播和垂直传播等方式,其中以密切接触传播为主,经破损皮肤感染为主要途径,并且多发生在成年,这对EHF疫源地的扩散和演变起着重要作用。而垂直传播对EHF疫源地保存与延续具有重要意义。

In our study, IFA was adopted to detect the epidemic haemorrhagic fever virus (E HFV) antigen and antibody. We studied on the mode of transmission of EHFV in mice and its epidemiologic significance. The results demonstrated that both horizontal and vertical modes of transmission existed in mice under natural circumstances. Horizontal transmission was noticed as the major mode of transmission of EHFV in mice which played an important role in the spread and de velopment of EHF natural loci. Vertical transmission seemed to act merely on the maintenance of EHF natural foci in mice.
