The study of vectors and vector-borne diseases associated with ectoparasites from free-living Neotropical small wild felids is scarce, and the few existing studies on this theme focused on the genus Panthera, Paleartic species or in captive animals. For this reason, the aim of this study was to identify the diversity of ectoparasites and potentially associated Rickettsia and Bartonella species in free-ranging neotropical wild cats collected in the State of Rio Grande do Sul, southern Brazil. A total of 82 ticks, 10 fleas and 22 mites were collected from 18 Geoffroy's cats (Leopardus geoffroyi), 11 margays (Leopardus wiedii), two southern tiger cats (Leopardus guttulus), two jaguarundis (Herpailurus yagouaroundi), three ocelots (Leopardus pardalis) and two pumas (Puma concolor). We identified four tick species: Rhipicephalus microplus and three species from genus Amblyomma, the most frequent being Amblyomma aureolatum; three flea species corresponding to Ctenocephalides felis, Xenopsylla cheopis, and Pulex irritans; and one mite of genus Eutrombicula. In ectoparasites we found DNA of Rickettsia parkeri and Rickettsia asembonensis in ticks and DNA of Bartonella clarridgeiae, Bartonella sp. and R. asembonensis in fleas. Our results highlight the evidences of vectors and vector-borne agents in wild animals, and their potential wide distribution in the Pampa biome and the southernmost portion of the Atlantic Rainforest in Brazil.
对来自自由生活的新热带小型野生猫科动物的寄生虫和与寄生虫相关的媒介的研究很少，而关于这个主题的少数现有研究集中在 Panthera 属、古北界物种或圈养动物上。因此，本研究的目的是确定在巴西南里奥格兰德州自由生活的新热带野生猫科动物中寄生虫和潜在相关的立克次体和巴尔通体物种的多样性。从 18 只 Geoffrey 猫（Leopardus geoffroyi）、11 只 Margay（Leopardus wiedii）、2 只南方虎猫（Leopardus guttulus）、2 只Jaguarundi（Herpailurus yagouaroundi）、3 只Ocelot（Leopardus pardalis）和 2 只美洲狮（Puma concolor）中收集了 82 只蜱虫、10 只跳蚤和 22 只螨虫。我们鉴定出了四种蜱虫：Rhipicephalus microplus 和三种属于 Amblyomma 属的物种，最常见的是 Amblyomma aureolatum；三种跳蚤分别为 Ctenocephalides felis、 Xenopsylla cheopis 和 Pulex irritans；以及一种属于 Eutrombicula 属的螨虫。在寄生虫中，我们在蜱虫中发现了 Rickettsia parkeri 和 Rickettsia asembonensis 的 DNA，在跳蚤中发现了 Bartonella clarridgeiae、Bartonella sp. 和 R. asembonensis 的 DNA。我们的研究结果突出了野生动物中媒介和媒介传播病原体的证据，以及它们在潘帕斯生物群落和巴西大西洋雨林最南端的广泛分布。
