Megjegyzések:	Background: Birds have long been known as carriers of ticks, but data from the literature are lacking on their roleas a reservoir in the epidemiology of certain tick-borne disease-causing agents. Therefore, the aim of this study wasto evaluate the presence of three emerging, zoonotic tick-borne pathogens in blood samples and ticks of birds andto assess the impact of feeding location preference and migration distance of bird species on their tick infestation.Methods: Blood samples and ticks of birds were analysed with TaqMan real-time PCRs and conventional PCRfollowed by sequencing.Results: During the spring and autumn bird migrations, 128 blood samples and 140 ticks (Ixodes ricinus,Haemaphysalis concinna and a Hyalomma specimen) were collected from birds belonging to 16 species. Theprevalence of tick infestation and the presence of tick species were related to the feeding and migration habits ofavian hosts. Birds were shown to be bacteraemic with Rickettsia helvetica and Anaplasma phagocytophilum, but notwith Candidatus Neoehrlichia mikurensis. The prevalence of rickettsiae was high (51.4%) in ticks, suggesting thatsome of them may have acquired their infection from their avian host.Conclusion: Based on the present results birds are potential reservoirs of both I. ricinus transmitted zoonoticpathogens, R. helvetica and A. phagocytophilum, but their epidemiological role appears to be less importantconcerning the latter, at least in Central Europe.
