West Nile fever and encephalitis caused by West Nile virus ( WNV) is maintained in a natural transmission cycle involving mosquito vectors and bird reservoir hosts, with the fatality of 4%~ 11%. 西尼罗病毒(Westnilevirus,WNV)感染是一种经蚊虫传播、以鸟类为主要动物宿主的自然疫源性疾病,在临床上可表现为西尼罗热或西尼罗脑炎,病死率4~11%。
An experimental study on immune cross-reaction between West Nile virus and Japanese encephalitis virus 西尼罗病毒与乙脑病毒免疫交叉反应的实验研究
Objective To compare the biological characteristics of West Nile virus ( WNV) and Japanese encephalitis virus ( JEV), including cells sensitivity, pathogenicity, viral morphology, as well as the results of immunological and molecular biological detection. 目的对西尼罗病毒(WNV)和乙脑病毒(JEV)的致细胞病变效应(CPE)、致病性、形态学、免疫学和分子生物学性状进行比较,为WNV感染的鉴别诊断提供依据。
Diseases caused by mosquito-borne viruses, especially Dengue fever, are reaching disastrous levels. In the U.S., the West Nile encephalitis virus is rapidly spreading westward. 其他蚊媒病如登革热日趋严重;美国西部西尼罗河脑炎病毒也在迅速蔓延。
