The prevalence of ticks infected by Borrelia burgdorferi sensu lato on birds during their migrations was studied in Switzerland. A total of 1,270 birds captured at two sites were examined for tick infestation. Ixodes ricinus was the dominant tick species. Prevalences of tick infestation were 6% and 18.2% for birds migrating northward and southward, respectively. Borrelia valaisiana was the species detected most frequently in ticks, followed by Borrelia garinii and Borrelia lusitaniae. Among birds infested by infected ticks, 23% (6/26) were infested by B. lusitaniae-infected larvae. Migratory birds appear to be reservoir hosts for B. lusitaniae.
在瑞士,研究了鸟类迁徙期间感染伯氏疏螺旋体狭义种的蜱的患病率。在两个地点捕获的总共1270只鸟被检查是否有蜱虫寄生。蓖麻硬蜱是主要的蜱种。向北和向南迁徙的鸟类的蜱虫寄生率分别为6%和18.2%。瓦莱州疏螺旋体是在蜱虫中检测到最频繁的物种,其次是加林疏螺旋体和葡萄牙疏螺旋体。在被感染蜱虫寄生的鸟类中,23%(6/26)被感染葡萄牙疏螺旋体的幼虫寄生。候鸟似乎是葡萄牙疏螺旋体的储存宿主。
