在北美发现了两个棕狗蜱系（Rhipicephalus sanguineus sensu lato (s.l.)， Latreille[蜱螨：伊蚊科]）：温带和热带。为了表征这些谱系在该地区的分布并评估季节性活动，研究人员对2018年至2021年期间从50个州中的25个州的不同地点收集的数百只狗和猫的血鼠进行了12S rRNA线粒体基因片段测序。在20个州的宠物中发现的温带侵染占主导地位（78.5%），其中大部分（83.5%）来自年平均日平均气温<20℃的地区。热带蜱属较少（19.3%），来自15个州，大部分（80.0%）热带蜱属来自年平均日平均气温为20℃的地区。虽然没有获得所有狗的旅行历史，但当在较冷的地区发现热带血统感染时，与兽医的后续对话表明，其中一些感染可能是由于狗最近的旅行造成的。来自亚利桑那州和德克萨斯州的有限数量（2.2%）的狗同时感染了这两种血统。在一年中每个月都从宠物身上收集了温带和热带蜱。温带系侵染主要在3月至8月收集，而热带系侵染通常在6月至11月收集。这些数据证实，在美国至少存在两种血鼠谱系，每一种都在不同的重叠地理上占主导地位，并表明每种谱系的活动高峰出现在一年中的不同时间。
Two lineages of brown dog ticks (Rhipicephalus sanguineus sensu lato (s.l.), Latreille [Acari: Ixodidae]) have been described in North America: temperate and tropical. To characterize the distribution of these lineages across this region and evaluate seasonal activity, a 12S rRNA mitochondrial gene fragment was sequenced from R. sanguineus s.l. collected from hundreds of dogs and cats from different locations across 25 of the 50 states from 2018 to 2021. Infestations with temperate lineage predominated (78.5%) and were identified on pets from 20 states, with most (83.5%) from areas with annual mean daily average temperature <20°C. Tropical lineage submissions were less common (19.3%), submitted from 15 states, and most (80.0%) tropical lineage ticks were from areas with an annual mean daily average temperature >20°C. Although travel history was not obtained for all dogs, when tropical lineage infestations were found in colder regions, follow up conversations with veterinarians suggested some of these infestations may have resulted from recent travel of dogs. A limited number (2.2%) of dogs from Arizona and Texas were co-infested with both lineages. Both temperate and tropical lineage ticks were collected from pets in every month of the year. Temperate lineage infestations were primarily collected March through August while tropical lineage infestations were more often collected June through November. These data confirm at least two lineages of R. sanguineus s.l. are present in the United States, each predominating in distinct, overlapping geographies, and suggest that peak activity of each lineage occurs at different times of the year.
