【摘要】 本文报道两株对小鼠无致病性虫媒病毒对乙脑病毒在组织培养、小鼠及三带喙库蚊体内均能干扰乙脑病毒的增殖,使其感染滴度降低2～3个对数。作者认为这些非致病性虫媒病毒在生态学中的干扰作用可能是引起乙脑隐性感染的原因之一。更多还原

【Abstract】 During a study of certain biological properties of newly isolated viruses, BM81014 and BM81071 viruses were found able to interfere with multiplication of JE virus in tissue culture, such as in C6/36 cells( a clone of Aedes albopictus cells) and chick embryo cells,as well as in mice and Culex tritaeniorhynchus, causing a decrease of JEV titer of 2-3Log. A hypothesis of non-pathogenic virus being a possible cause of subclimcal JE virus infection was proposed and discussed.更多还原
