BACKGROUND
Mosquitoes are the primary vectors of West Nile virus (WNV). Ticks have, however, been suggested to be potential reservoirs of WNV. In order to investigate their role in the spread of the virus, ticks, which had been collected from birds migrating northwards from Africa to Europe, were analyzed for the potential presence of WNV-RNA.
METHODS
On the Mediterranean islands Capri and Antikythira a total of 14,824 birds were captured and investigated from which 747 ticks were collected.
RESULTS AND CONCLUSION
Most of the identified ticks (93%) were nymphs and larvae of Hyalomma marginatum sensu lato, most of which were or appear to be Hyalomma rufipes. Of these ticks 729 were individually screened for WNV-RNA. None of the ticks was found to be WNV positive. Thus, there was no evidence that Hyalomma marginatum s.l. ticks play a role in the spread of WNV from Africa to Europe.
背景
蚊子是西尼罗河病毒（WNV）的主要传播媒介。然而，蜱虫被认为是WNV的潜在宿主。为了研究它们在病毒传播中的作用，对从非洲向北迁徙至欧洲的鸟类身上采集的蜱虫进行了分析，以检测WNV-RNA的潜在存在情况。
方法
在卡普里岛和安提基西拉岛这两个地中海岛屿上，共捕获并调查了14,824只鸟类，从中采集到747只蜱虫。
结果与结论
鉴定出的蜱虫中，大多数（93%）是边缘璃眼蜱的若虫和幼虫，其中大多数是或似乎是红腿璃眼蜱。对这些蜱虫中的729只分别进行了WNV-RNA筛查。未发现任何蜱虫呈WNV阳性。因此，没有证据表明边缘璃眼蜱在WNV从非洲传播到欧洲的过程中发挥作用。
