Although there are reports on many species of ticks infesting dogs, including from the Amazon region, simultaneous infestations by different species are poorly discussed in the literature. Therefore, this study aimed to report simultaneous infestations in dogs by different species of ticks, involving up to six species, in two areas of the western Brazilian Amazon, specifically in the border region between the states of Rondônia and Amazonas, in northern Brazil. Ticks were collected between 2021 and 2023 from dogs on private properties surrounding two conservation units: Municipal Natural Park of Porto Velho (NP), and Mapinguari National Park (MNP). The following species were identified: Amblyomma ovale, Amblyomma scalpturatum, Amblyomma latepunctatum, Amblyomma oblongogutattum, Amblyomma coelebs, Amblyomma naponense and Rhipicephalus sanguineus s.l.. Among the 342 dogs sampled, 184 were from the area around the NP and 158 were from the area around the MNP. A total of 34 dogs (9.9%) exhibited simultaneous tick species infestations, ranging from two to six tick species; 26 dogs (16.5%) with simultaneous infestations were from the MNP area, and eight dogs (4.3%) were from the NP area. This study is the first to report the simultaneous occurrence of four, five or six tick species on individual dogs.
尽管有许多关于寄生在狗身上的蜱虫种类的报告，包括来自亚马逊地区的报告，但文献中对不同种类蜱虫同时寄生的情况讨论较少。因此，本研究旨在报告在巴西亚马逊西部的两个地区，特别是在巴西北部朗多尼亚州和亚马逊州之间的边境地区，狗身上不同种类蜱虫的同时寄生情况，涉及多达六种蜱虫。2021年至2023年期间，从两个保护单位周边私人领地的狗身上采集蜱虫：波多韦柳市立自然公园（NP）和马平瓜里国家公园（MNP）。鉴定出的蜱虫种类如下：卵形钝缘蜱、刻点钝缘蜱、后点钝缘蜱、长腹钝缘蜱、孤独钝缘蜱、纳蓬钝缘蜱和血红扇头蜱（狭义）。在342只采样的狗中，184只来自NP周边地区，158只来自MNP周边地区。共有34只狗（9.9%）出现了不同种类蜱虫的同时寄生，涉及的蜱虫种类从两种到六种不等；26只同时寄生的狗（16.5%）来自MNP地区，八只狗（4.3%）来自NP地区。本研究首次报告了单只狗身上同时出现四种、五种或六种蜱虫的情况。
