本文叙述了1993年对大兴安岭森林脑炎传播媒介的调查,从采集到的1千多只蜱中,分离到3株森林脑炎病毒。经同标准株的交叉中和实验证实,为森林脑炎病毒株。从而首次确定内蒙古大兴安岭林区为森林脑炎自然疫源地,该项调查为大兴安岭森林脑炎的进一步研究提供了科学的依据。
This article describes a survey of the forest encephalitis transmission media in the Greater Khingan Range in 1993. From the collected more than 1,000 ticks, three forest encephalitis viruses were isolated. Cross-neutralization experiments with the standard strains confirmed that the forest encephalitis virus strain. Thus, for the first time, the natural forest encephalitis of Daxingan Mountains in Inner Mongolia was identified as a natural foci, and the survey provided a scientific basis for further study of forest encephalitis in Daxing’anling.
