蜱传播的病原体如莱姆病、疏螺旋体、嗜吞噬细胞无形体、立克次体属。和Babelus spp.在动物和人类中引起多种疾病。虽然它们对人类新出现的疾病的重要性正在增加，但关于它们的生态学的许多问题仍然不清楚。2007年春，在波罗的海的一个鸟类保护岛上，从11个物种的99只鸟类中收集了191只蓖麻硬蜱（阿卡里：硬蜱科）蜱，以测试它们的疏螺旋体属，A.嗜吞噬细胞立克次体、立克次体属和Babelus spp.感染.采用聚合酶链反应（PCR）、限制性片段长度多态性和序列分析对病原体进行鉴定。大多数蜱虫检测呈阳性的鸟类是欧洲知更鸟和画眉。疏螺旋体DNA检出率为14.1%，A.立克次体7.3%，巴氏杆菌2.6%。在4.7%的蜱虫中。不同病原体的混合感染发生在6只蜱（3.1%）。11只蜱（5只幼虫，6只蜱）感染了阿氏疏螺旋体，这一事实表明，与目前的观点相反，鸟类可能是该物种的储存宿主。在立克次体感染中，我们鉴定了摩纳哥立克次体和瑞士立克次体。当我们检测到五种立克次体时。如果有感染的幼虫和两只鸟携带一只以上受感染的蜱，这些病原体可能从鸟传播给蜱。巴氏杆菌感染的进一步表征揭示了分歧巴氏杆菌和田鼠巴氏杆菌。巴贝虫的发生。在总共五只幼虫中发现的一只蜱虫表明，鸟类可能能够感染蜱虫，至少是Ba。Microti，一种被认为不会在蜱虫中经卵传播的物种。
Tick-borne pathogens such as Lyme borreliosis spirochaetes, Anaplasma phagocytophilum, Rickettsia spp. and Babesia spp. cause a great variety of diseases in animals and humans. Although their importance with respect to emerging human diseases is increasing, many issues about their ecology are still unclear. In spring 2007, 191 Ixodes ricinus (Acari: Ixodidae) ticks were collected from 99 birds of 11 species on a bird conservation island in the Baltic Sea in order to test them for Borrelia spp., A. phagocytophilum, Rickettsia spp. and Babesia spp. infections. Identification of the pathogens was performed by polymerase chain reaction (PCR), restriction fragment length polymorphism and sequence analysis. The majority of birds with ticks testing positive were European robins and thrushes. Borrelia DNA was detected in 14.1%, A. phagocytophilum in 2.6%, rickettsiae in 7.3% and Babesia spp. in 4.7% of the ticks. Co-infections with different pathogens occurred in six ticks (3.1%). The fact that 11 ticks (five larvae, six nymphs) were infected with Borrelia afzelii suggests that birds may, contrary to current opinion, serve as reservoir hosts for this species. Among rickettsial infections, we identified Rickettsia monacensis and Rickettsia helvetica. As we detected five Rickettsia spp. positive larvae and two birds carried more than one infected tick, transmission of those pathogens from birds to ticks appears possible. Further characterization of Babesia infections revealed Babesia divergens and Babesia microti. The occurrence of Babesia spp. in a total of five larvae suggests that birds may be able to infect ticks, at least with Ba. microti, a species considered not to be transmitted transovarially in ticks.
