Blacklegged ticks (Ixodes scapularis) are vectors for several important human diseases, including Lyme disease, human granulocytic anaplasmosis (HGA), and human babesiosis, caused by Borrelia burgdorferi, Anaplasma phagocytophilum, and Babesia microti, respectively. The continued northward range expansion of blacklegged ticks and associated pathogens is an increasing public health concern in Canada.
The Thousand Islands region of eastern Ontario has recently been identified as a new endemic area for Lyme disease in Canada, but the occurrence of other pathogens in ticks in this area has not been fully described. Our objectives were to determine the prevalence of A. phagocytophilum and B. microti in small mammals and questing ticks in the Thousand Islands area and identify the strains of A. phagocytophilum circulating in ticks in the area.
