Anaplasma phagocytophilum is the causative agent of granulocytic anaplasmosis in humans, dogs, cats, horses and tick-borne fever in ruminants. In Europe, its main vector is the tick species Ixodes ricinus. In this study, spleen and liver samples, as well as ticks from 18 wild-living mammals (belonging to seven species) were analysed for the presence of A. phagocytophilum with molecular methods. The zoonotic ecotype-I of A. phagocytophilum was identified in a European wildcat (Felis silvestris) and its tick, a European pine marten (Martes martes) and a Eurasian red squirrel (Sciurus vulgaris). All PCR-positive samples were collected in 2019 and originated in the same geographic area. These results indicate that taxonomically diverse mammalian species can maintain the local enzootic cycle of the same genotype of A. phagocytophilum. To the best of our knowledge, this is the first report of the zoonotic variant of A. phagocytophilum in the wildcat and in the European pine marten in a broad geographical context, as well as in the red squirrel in Hungary. Since all these host species are well known for their urban and peri-urban presence, the results of this study verify their role in the synanthropic enzootic cycle of granulocytic anaplasmosis and tick-borne fever.
