At least thirty species of wild carnivores have been recorded harboring Bartonella, and one of the most common pathogenic species infecting them is Bartonella rochalimae, which can cause endocarditis in humans and dogs. This bacterium can infect various mammals including wild carnivores, as well as ectoparasitic vectors such as fleas and ticks. Here we report the presence of B. rochalimae, in a Pulex simulans flea collected from a Mephitis macroura skunk in the municipality of Santa Cruz in Sonora, Mexico.
Fleas were collected from a M. macroura in Sonora, Mexico, in October 2019. They were identified to species level and subsequently tested for the presence of Bartonella using molecular tools including conventional PCR, sequencing, and phylogenetic analysis.
A total of 10 P. simulans fleas (one male, nine females) were collected from the M. macroura skunk. The PCR and phylogenetic analysis indicated a prevalence of 10% (1/10) and a sequence clustered with the clade of B. rochalimae.
We confirmed the presence of B. rochalimae in a P. simulans flea collected from a M. macroura skunk in the area of Santa Cruz, Sonora, Mexico. Based on our results and previous studies in northern Mexico, which are consistent, it is necessary to continue monitoring Bartonella in M. macroura skunks and their fleas, since they could be important reservoirs of this bacterium in northern Mexico.
已记录到至少30种野生食肉动物携带巴尔通体，其中感染它们的最常见致病物种之一是罗氏巴尔通体，它可导致人类和犬类患心内膜炎。这种细菌可感染包括野生食肉动物在内的各种哺乳动物，以及跳蚤和蜱等外寄生媒介。在此，我们报告在从墨西哥索诺拉州圣克鲁斯市的一只大尾臭鼬身上采集的一只拟蚤中存在罗氏巴尔通体。
2019年10月，从墨西哥索诺拉州的一只大尾臭鼬身上采集跳蚤。将它们鉴定到物种水平，随后使用包括常规PCR、测序和系统发育分析在内的分子工具检测巴尔通体的存在。
从大尾臭鼬身上共采集到10只拟蚤（1只雄性，9只雌性）。PCR和系统发育分析表明，患病率为10%（1/10），且一个序列与罗氏巴尔通体分支聚类。
我们证实了在从墨西哥索诺拉州圣克鲁斯地区的一只大尾臭鼬身上采集的一只拟蚤中存在罗氏巴尔通体。根据我们的结果以及墨西哥北部此前的一致研究，有必要继续监测大尾臭鼬及其跳蚤中的巴尔通体，因为它们可能是这种细菌在墨西哥北部的重要宿主。
