Molecular Detection of Borrelia burgdorferi sensu lato, Borrelia miyamotoi, Babesia odocoilei, Babesia microti and Anaplasma phagocytophilum in Ixodes Ticks Collected across Canada

Tick-borne zoonotic diseases are a profound challenge to healthcare practitioners, and an overwhelming scourge to patients worldwide. On the whole, patients have great difficulty getting diagnosed and treated, and often become chronically ill. In this study, we tested 224 ticks consisting of Ixodes angustus, Ixodes pacificus, and Ixodes scapularis. Using real-time PCR and nested PCR, we obtained the following positives: Borrelia burgdorferi sensu lato (n = 74), Borrelia miyamotoi (n = 4), Babesia odocoilei (n = 82), Babesia microti (n = 1), and Anaplasma phagocytophilum (n = 8). Markedly, B. odocoilei and B. burgdorferi were detected in I. scapularis ticks nationwide. As well, the Canada-wide prevalence of B. burgdorferi s.l. and B. odocoilei in I. scapularis adults was 40% and 36%, respectively. The statistical ratio of B. odocoilei to B. microti in I. scapularis adults was 60 to 1. Babesia odocoilei is, unquestionably, the predominant Babesia sp. across Canada. We provide the first report of B. odocoilei in an I. angustus tick. In addition, we unfurl the first report of B. odocoilei in I. scapularis in British Columbia, Alberta, Saskatchewan, Manitoba, Prince Edward Island, and Newfoundland and Labrador. From a professional healthcare standpoint, I. scapularis ticks are just as likely to be infected with Babesia odocoilei as Borrelia burgdorferi s.l. Since people spend considerable time in outdoor areas, clinicians must be familiar with current acumen in tick-borne zoonotic diseases.
