Tick-borne zoonotic diseases have an economic and societal impact on the well-being of people worldwide. In the present study, a high frequency of , a red blood cell parasite, was observed in the Huronia area of Ontario, Canada. Notably, 71% (15/21) blacklegged ticks, , collected from canine and feline hosts were infected with . Consistent with U.S. studies, 12.5% (4/32) of questing adults collected by flagging in various parts of southwestern Ontario were positive for . Our data show that all strains in the present study have consistent genetic identity, and match type strains in the GenBank database. The high incidence of in the Huronia area indicates that this babesial infection is established, and is cycling enzootically in the natural environment. Our data confirm that has wide distribution in southern Ontario.
蜱传人畜共患病对全球人类的健康有着经济和社会影响。在本研究中,在加拿大安大略省的休伦尼亚地区观察到一种红细胞寄生虫——[具体寄生虫名称未给出]的高感染率。值得注意的是,从犬类和猫类宿主身上采集的71%(15/21)的黑脚蜱——[蜱的具体名称未给出]感染了[具体寄生虫名称未给出]。与美国的研究一致,通过在安大略省西南部不同地区拖旗采集的12.5%(4/32)的饥饿[蜱的具体发育阶段未给出]成虫对[具体寄生虫名称未给出]呈阳性。我们的数据表明,本研究中的所有[具体寄生虫名称未给出]菌株具有一致的基因特征,并且与GenBank数据库中的模式菌株匹配。休伦尼亚地区[具体寄生虫名称未给出]的高发病率表明这种巴贝斯虫感染已经确立,并且在自然环境中以动物流行病的形式循环传播。我们的数据证实[具体寄生虫名称未给出]在安大略省南部广泛分布。
