Abstract

Ticks parasitize various hosts, including humans, and are known to transmit pathogens that can be harmful not only to animals but also to humans. To evaluate the possible presence of pathogens in ticks, we aimed to collect and identify tick fauna specimens in Lagoa Comprida Municipal Natural Park, an anthropogenic urban area located in Aquidauana, Mato Grosso do Sul, Brazil. A total of 1216 ticks, of which 51.2% were Amblyomma sculptum, 1.2% were Amblyomma dubitatum, and 41% were Amblyomma spp. were collected. These results show that the prevalence of A. sculptum is significantly higher than that of A. dubitatum across all four seasons. Molecular analyses revealed positive samples for the genus Babesia, including the confirmation of Babesia bigemina in an A. sculptum specimen, marking the first record of this relationship. This unexpected finding demands greater attention and deeper analysis in the context of the epidemiology of tick-borne diseases.

在巴西南马托格罗索州的 Amblyomma sculptum（Berlese，1888 年）蜱虫中发现了 Babesia bigemina（smith 和 Kilbourne，1893 年）。

蜱虫寄生在包括人类在内的各种宿主身上，众所周知，蜱虫会传播病原体，这些病原体不仅会对动物造成危害，也会对人类造成危害。为了评估蜱虫中可能存在的病原体，我们在位于巴西南马托格罗索州阿奎达纳的人为城市地区拉戈阿孔普里达市立自然公园采集并鉴定了蜱虫动物标本。共收集到 1216 只蜱虫，其中 51.2% 为 Amblyomma sculptum，1.2% 为 Amblyomma dubitatum，41% 为 Amblyomma spp.。这些结果表明，在所有四个季节中，A. sculptum 的流行率明显高于 A. dubitatum。分子分析显示，巴贝西亚属的样本呈阳性，包括在一个 A. sculptum 标本中确认了巴贝西亚属 bigemina，这是首次记录到这种关系。这一意想不到的发现需要在蜱传疾病流行病学方面给予更多关注和更深入的分析。
