Ixodes ricinus (Acari: Ixodida) is the main vector in Europe of Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum and Babesia microti. Wolinski National Park (WNP) is situated by the Baltic Sea and is frequently visited by tourists. The aim of the study was to determine the potential risk of exposure to tick borne infection with B. burgdorferi s.l., A. phagocytophilum and B. microti on the areas of WNP. In total, 394 I. ricinus were tested. The pathogens in ticks were detected by PCR, nested PCR, RFLP and sequencing. Altogether, pathogens were detected in 12.69% of the studied ticks. B. burgdorferi s.l., was shown in 0.25% of the studied I. ricinus, while A. phagocytophilum and B. microti were detected in 1.01% and 10.65% of studied ticks, respectively. Co-infection by A. phagocytophilum and B. microti was shown in only one I. ricinus nymph. Analysis of B. burgdorferi s.l., genospecies showed that 0.25% of the studied ticks were infected with Borrelia garinii. The obtained results show the potentially high human risk of exposure to tick-borne infection with B. microti, and the low potential risk of infection with B. garinii and A. phagocytophilum on the studied areas of WNP.
