Abstract

We report the detection and isolation of four almost identical strains of West Nile virus (WNV) lineage 2from Culex modestus mosquitoes collected at three fish ponds in South Moravia, Czech Republic, during August 2013. Phylogenetic analysis demonstrated that the Czech WNV strains isolated are closely related to Austrian, Italian and Serbian strains reported in 2008,2011 and 2012, respectively. Our findings show the current northernmost range of lineage 2 WNV in Europe.

摘要

我们报告了在 2013 年 8 月于捷克南摩拉维亚的三个鱼塘中采集的库蚊中检测到并分离出的 4 株近乎相同的西尼罗河病毒（WNV）2 型谱系株。系统进化分析表明，分离出的捷克 WNV 株与 2008 年、2011 年和 2012 年分别在奥地利、意大利和塞尔维亚报告的毒株密切相关。我们的研究结果表明，WNV2 型在欧洲的最北分布范围目前已到达这里。
