In this study we present the first evidence that B. microti and A. phagocytophilum pathogens are present in wild rodents in Finland. A. phagocytophilum is known to cause tick-borne fever in cattle in Finland and, recently, a domestic cat was diagnosed with A. phagocytophilum infection B. microti, in turn, has been reported in a single Ixodes persulcatus tick in western Finland. However, this is the first study examining the presence of A. phagocytophilum and B. microti in wildlife reservoir host species.
