Despite the recognized epidemiological importance of ticks as vectors for pathogens that cause numerous zoonotic and veterinary diseases, data regarding the pathogens of pet dogs and their parasitic ticks in the Junggar Basin are scarce. In this study, a total of 178 blood samples and 436 parasitic ticks were collected from pet dogs in Junggar Basin, Xinjiang Uygur Autonomous Region (XUAR), north-western China. All ticks were identified as sensu stricto (s.s.) according to morphological and molecular characteristics. s.s. ticks were collected from pet dogs in China for the first time. Seven tick-borne pathogens, such as R. barbariae, spp., , and , were detected from ticks, whereas the first five bacteria were detected from blood samples of dogs. spp. was the most predominant pathogen in both blood samples and ticks of pet dogs, with the detection rates of 16.29 and 16.74%, respectively. Moreover, 17 ticks and 1 blood sample were co-infected with two pathogens, and 1 tick was co-infected with three pathogens. This study provided molecular evidence for the occurrence of spp., spp., spp., and spp. circulating in pet dogs and their parasitic ticks in Junggar Basin, north-western China. These findings extend our knowledge of the tick-borne pathogens in pet dogs and their parasitic ticks in Central Asia; therefore, further research on these pathogens and their role in human and animal diseases is required.
尽管蜱作为多种人畜共患病和兽病病原体的传播媒介在流行病学上具有公认的重要性，但关于准噶尔盆地宠物狗及其寄生蜱的病原体的数据却很稀少。在本研究中，从中国西北部新疆维吾尔自治区（XUAR）准噶尔盆地的宠物狗身上共采集了178份血液样本和436只寄生蜱。根据形态学和分子特征，所有蜱均被鉴定为狭义种（s.s.）。狭义种蜱首次在中国宠物狗身上被采集到。从蜱中检测到7种蜱传病原体，如巴氏立克次体、某些种、其他种等，而前5种细菌是从狗的血液样本中检测到的。某种菌是宠物狗血液样本和蜱中最主要的病原体，检测率分别为16.29%和16.74%。此外，17只蜱和1份血液样本同时感染了两种病原体，1只蜱同时感染了三种病原体。本研究为准噶尔盆地中国西北部宠物狗及其寄生蜱中某种菌、某些种、其他种等的循环存在提供了分子证据。这些发现扩展了我们对中亚宠物狗及其寄生蜱中蜱传病原体的认识；因此，需要对这些病原体及其在人类和动物疾病中的作用进行进一步研究。
