Dermacentor albipictus, a common one-host tick of large animals in North America, is most often reported from moose (Alces alces) and is rarely implicated as a parasite of cats and dogs. From 2018 to 2020, 4 dogs and 4 cats from United States and 3 dogs from Canada were infested with D. albipictus. The specimens were collected and submitted to university diagnostic specialists by veterinary clinics in Indiana, Kentucky, Minnesota, Colorado, Wyoming, Utah, Alberta, and British Columbia between the months of October to February (United States) and April to June (Canada). Six adults and five nymphal D. albipictus were collected in the United States while three adults were collected from pets in Canada, and most often a single D. albipictus was present. Identification of specimens collected in the United States were confirmed by amplification and sequencing of 16S rRNA and ITS-2 gene fragments. Rickettsia spp. were not detected in any D. albipictus collected in the United States by 17 kDa-based PCR. As tick populations continue to increase and expand in North America, correct identification of ticks collected from pets is critical to accurately track the progression and spread of ticks and tick-borne diseases.
白纹革蜱，一种常见的北美大型动物一宿主蜱，多报道于驼鹿（Alces alces），很少被认为是猫和狗的寄生虫。2018 年至 2020 年，美国的 4 只狗和 4 只猫以及加拿大的 3 只狗感染了白纹革蜱。这些标本由印第安纳州、肯塔基州、明尼苏达州、科罗拉多州、怀俄明州、犹他州、艾伯塔省和不列颠哥伦比亚省的兽医诊所收集，并提交给大学诊断专家，收集时间为 10 月至 2 月（美国）和 4 月至 6 月（加拿大）。在美国收集了 6 只成蜱和 5 只若蜱，在加拿大从宠物身上收集了 3 只成蜱，而且通常只有一只白纹革蜱。在美国收集的标本通过 16S rRNA 和 ITS-2 基因片段的扩增和测序来确认鉴定。通过基于 17 kDa 的 PCR 在美国采集的白纹革蜱中未检测到任何立克次体。随着北美的蜱种群继续增加和扩大，正确鉴定从宠物身上采集的蜱对于准确跟踪蜱和蜱传疾病的进展和传播至关重要。
