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.
