Abstract: The objectives of the present research were to survey potential vertebrate host and tick species for evidence of infections with POWV and other arthropod-borne pathogens including West Nile virus, Heartland virus, Anaplasma phagocytophilum, Babesia microti, Borrelia miyamotoi, B. burgdorferi and Ehrlichia chaffeensis in mammalian wildlife, dogs and ticks in southern Ontario. During the summers of 2015-2016, ticks and tissues were collected from carcasses of free-ranging, medium-sized mammals; blood and ticks were collected from live-trapped mammals, and ticks removed from dogs were collected from local veterinary clinics. Albeit rarely, evidence of the presence of POWV was found both by polymerase chain reaction in ticks and serological tests in groundhogs (Marmota monax) and striped skunks (Mephitis mephitis). Evidence of A. phagocytophilum and B. burgdorferi was also rarely detected in Ixodes scapularis ticks. These findings emphasize the importance of both broad and targeted surveillance strategies for investigating emerging tick-borne diseases.
