Tick-borne pathogen epidemiology involves vectors, in Europe mainly Ixodes ricinus, and vertebrate hosts. Ruminants are reservoirs for Anaplasma phagocytophilum, but not Borrelia burgdorferi sensu lato (s.l.), possibly clearing the infection from ticks. However, such clearance is epidemiologically relevant nymphal Of 1874 ticks collected wildlife present study, 1535 spp. (796 nymphs, 739 females) were tested by qPCR, with a proportion of 26.3% (nymphs: 24.5%, females: 28.3%) positive 87.4% A. phagocytophilum 62.8%, 92.4%).
