Cats that spend time outdoors and dogs are particularly at risk of exposure to ticks and the pathogens they transmit. A retrospective study on data collected through passive tick surveillance was conducted to estimate the risk of exposure to tick-borne pathogens in cats and dogs bitten by blacklegged ticks (Ixodes scapularis) in the province of Quebec, Canada, from 2010 to 2017. Blacklegged ticks collected from these host animals were tested by PCR for Borrelia burgdorferi sensu stricto, Borrelia miyamotoi, Anaplasma phagocytophilum, and Babesia microti. A total of 13,733 blacklegged ticks were collected from 12,547 animals. Most ticks were adult females and partially engorged. In total, 1,774 cats were infested with ticks and 22.6% and 2.7% of these animals were bitten by at least one tick infected with B. burgdorferi and A. phagocytophilium, respectively. For the 10,773 tick infested dogs, 18.4% were exposed to B. burgdorferi positive ticks while 1.9% of infested dogs were exposed to ticks infected with A. phagocytophilum. The risk of exposure of both cats and dogs to B. miyamotoi and B. microti was lower since only 1.2% and 0.1% of ticks removed were infected with these pathogens, respectively. Travelling outside of the province of Quebec prior to tick collection was significantly associated with exposure to at least one positive tick for B. burgdorferi, A. phagocytophilum and B. microti. Animals exposed to B. burgdorferi or B. miyamotoi positive tick(s) were at higher risk of being concurrently exposed to A. phagocytophilum; higher risk of exposure to B. microti was also observed in animals concurrently exposed to B. burgdorferi. The odds of dogs having B. burgdorferi antibodies were higher when multiple ticks were collected on an animal. The testing and treatment strategies used on dogs bitten by infected ticks were diverse, and misconceptions among veterinarians regarding the treatment of asymptomatic but B. burgdorferi-seropositive dogs were noted. In conclusion, our study demonstrates that cats and dogs throughout Quebec are exposed to blacklegged ticks infected with B. burgdorferi and A. phagocytophilum, and veterinarians across the province need to be aware of this potential threat to the health of pets and their owners.

魁北克市被肩胛硬蜱感染的猫和狗接触蜱传病原体:一项为期 8 年的监测研究
花时间在户外的猫和狗特别容易接触蜱虫及其传播的病原体。对通过被动蜱监测收集的数据进行了一项回顾性研究,以评估 2010 年至 2017 年在加拿大魁北克省被黑腿蜱(Ixodes scapularis)咬伤的猫和狗接触蜱传病原体的风险。 黑腿蜱从这些宿主动物中收集的细菌通过 PCR 检测严格的伯氏疏螺旋体、宫本疏螺旋体、嗜吞噬细胞无形体和小巴贝斯虫。从 12,547 只动物中总共收集了 13,733 只黑腿蜱。大多数蜱是成年雌性,部分肿胀。总共有 1,774 只猫感染了蜱虫,其中 22.6% 和 2.7% 的猫被至少一只感染了伯氏疏螺旋体和吞噬细胞的蜱叮咬,分别。对于 10,773 只蜱虫感染的狗,18.4% 的狗暴露于 B. burgdorferi 阳性蜱,而 1.9% 的感染狗暴露于感染了A. phagocytophilum 的蜱虫。猫和狗接触 B. miyamotoi 和 B. microti 的风险较低,因为去除的蜱中分别只有 1.2% 和 0.1% 感染了这些病原体。在蜱收集之前在魁北克省以外旅行与接触至少一种 B. burgdorferi、A. phagocytophilum 和 B. microti 阳性蜱显着相关。暴露于 B. burgdorferi 或 B. miyamotoi 阳性蜱的动物同时暴露于 A. phagocytophilum 的风险更高;在同时暴露于 B. burgdorferi 的动物中也观察到更高的暴露于 B. microti 的风险。狗有 B 的几率。当在动物身上收集多个蜱时,伯氏疏螺旋体抗体更高。用于被感染蜱咬伤的狗的测试和治疗策略多种多样,并且注意到兽医对治疗无症状但 B. burgdorferi 血清阳性的狗的误解。总而言之,我们的研究表明,魁北克各地的猫和狗都暴露于感染了伯氏疏螺旋体和嗜噬细胞拟杆菌的黑腿蜱,全省的兽医需要意识到这种对宠物及其主人健康的潜在威胁。
