During spring and autumn 2001, we screened 13,260 migrating birds at Ottenby Bird Observatory, Sweden, and found 3.4% were infested with ticks. Four birds, each a different passerine species, carried tickborne encephalitis virus (TBEV)-infected ticks (Ixodes ricinus). Migrating birds may play a role in the geographic dispersal of TBEV-infected ticks.
2001年春秋两季，我们在瑞典奥滕比鸟类观测站对13260只候鸟进行了筛查，发现3.4%的鸟身上有蜱虫寄生。有4只鸟（分属不同的雀形目物种）身上携带着感染了蜱传脑炎病毒（TBEV）的蜱虫（蓖麻硬蜱）。候鸟可能在感染TBEV的蜱虫的地理扩散中发挥作用。
