Abstract

Purpose: 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.

Methods: 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.

Results: 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.

Conclusions: 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.

从墨西哥索诺拉州的一只大斑鼹鼠身上采集到的跳蚤体内的巴顿氏菌（Bartonella rochalimae）。

目的：根据记录，至少有三十种野生食肉动物携带巴顿氏菌，其中最常见的致病菌之一是罗卡氏巴顿氏菌，它可导致人类和狗患心内膜炎。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。在这里，我们报告了在墨西哥索诺拉州圣克鲁斯市从一只大斑鼬身上收集到的 Pulex simulans 跳蚤中发现了 B. rochalimae：方法：2019 年 10 月在墨西哥索诺拉州从一只大鼬身上采集到跳蚤。方法：2019 年 10 月，在墨西哥索诺拉州从一只美洲斑鼬身上采集了跳蚤，对跳蚤进行了物种鉴定，随后使用传统 PCR、测序和系统发育分析等分子工具对跳蚤进行了巴顿氏菌检测：结果：从大鼬身上共采集到 10 只 P. simulans 跳蚤（1 只雄性，9 只雌性）。聚合酶链式反应和系统进化分析表明其流行率为 10%（1/10），其序列与 B. rochalimae 支系聚类：我们证实，在墨西哥索诺拉州圣克鲁斯地区从鼠鼬身上采集到的 P. simulans 跳蚤中存在 B. rochalimae。我们的研究结果与之前在墨西哥北部进行的研究结果一致，因此有必要继续监测大袋鼠臭鼬及其跳蚤体内的巴顿氏菌，因为它们可能是墨西哥北部这种细菌的重要贮藏地。

期刊介绍： Acta Parasitologica is an international journal covering the latest advances in the subject. Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews. The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
