Over the years, tick-borne pathogens (TBPs) have garnered significant interest due to their medical, veterinary and economic importance. Additionally, TBPs have drawn attention to how these microorganisms interact with their own vectors, increasing the risk to human and animal infection of emerging and reemerging zoonoses. In this sense, ticks, which are obligate hematophagous ectoparasites, have a key role in maintaining and transmitting TBPs among humans and animals. The aim of this study was to assess the prevalence of neglected TBPs in mainland Portugal, namely spp., spp., spp. and . DNA fragments were detected in questing ticks collected from five different ecological areas under investigation. To the best of the authors' knowledge, this study reports new worldwide findings, including infecting , and sensu lato. Additionally, it presents new findings in Portugal of infecting and of presumably endosymbionts being detected in . Overall, there were 208 tick samples that were negative for all screened TBPs. The results herein obtained raise concerns about the circulation of neglected TBPs in mainland Portugal, especially in anthropophilic ticks, highlighting the importance of adopting a One Health perspective.
多年来，蜱传病原体（TBPs）因其在医学、兽医和经济方面的重要性而备受关注。此外，蜱传病原体还引发了人们对这些微生物如何与它们自身的传播媒介相互作用的关注，增加了新出现和重新出现的人畜共患病对人类和动物感染的风险。从这个意义上说，蜱作为专性吸血的体外寄生虫，在人类和动物之间维持和传播蜱传病原体方面起着关键作用。本研究的目的是评估葡萄牙大陆被忽视的蜱传病原体的流行情况，即 属、 属、 属和 属。在从所调查的五个不同生态区域采集的觅食蜱中检测到了DNA片段。据作者所知，本研究报告了新的全球发现，包括 感染 、 和 狭义种。此外，它还展示了在葡萄牙的新发现，即 感染 和在 中检测到可能的 内共生体。总体而言，有208个蜱样本对所有筛查的蜱传病原体均呈阴性。本文获得的结果引发了人们对葡萄牙大陆被忽视的蜱传病原体传播情况的担忧，特别是在嗜人蜱中，凸显了采用“同一健康”视角的重要性。
