The aim of this study was to examine the participation of roe deer, red deer, wild boar, and sheep Ixodes ricinus ticks from the Puszcza Wkrzańska Forest in Anaplasma phagocytophilum developmental cycle. Detection of A. phagocytophilum DNA was carried out on tissues collected from game animals, ticks infecting them, and ticks collected from vegetation in the hunting area, using a set of primers enabling the amplification of the 334 base pairs fragment of msp2 gene. 42.4% of the shot roe deer (25/59) were infected by l. ricinus ticks, as well as 30% (6/20) of red deer and 4.8% (1/21) of wild boars. A. phagocytophilum DNA was detected in tissues of 45.8% (27/59) of the sampled roe deer, 65% (13/20) red deer, and 4.8% (1/21) wild boar, and in 11.6% of the ticks infecting roe deer (12/103), in 5% (1/20) of the ticks infecting red deer, and in 5.5% (11/200) of the ticks collected from the vegetation in the area. The results suggest that roe and red deer are probable reservoirs of A. phagocytophilum, while the wild boar plays little or no role in the propagation of this parasite.
