The aim of the study was to establish the role of forest birds as reservoirsof Anaplasma phagocytophilum and Babesia spp. in Wielkopolski National Park. A total of 108 birds from9 species were collected between May-September 2002. Blood samples were taken from 84 specimens and 442individuals of the common tick, Ixodes ricinus, were collected from the birds. The 73 additional tickswere collected from vegetation. PCR amplification of a fragment of the epank 1 gene and 18S rRNA genewas used for detection of A. phagocytophilum and Babesia spp. DNA, respectively. Pathogen DNA was notdetected in any of the blood samples or ticks collected from birds. On the other hand, 3 ticks collectedfrom vegetation (4.1% of all examined specimens) were positive for A. phagocytophilum DNA. In spite ofthe high level of infestation of birds by I. ricinus, it is clear that they do not constitute a competentreservoir of A. phagocytophilum and Babesia in WNP. Additionally, I. ricinus is not a significant vectorin this area.
