This study aims to report the occurrence of parasitism by Amblyomma ovale (Koch, 1844) in dogs in the municipality of Apodi, Rio Grande do Norte, Brazil. Specimens were identified as being one female and two males of A. ovale, besides; the animal was infested by five females of Rhipicephalus (Boophilus) microplus and seven females and three males of R. sanguineus. The finding of A. ovale confirms results in the literature that these ticks, reported in several species of wild carnivores, can also infect dogs in Brazil. The distribution of this tick species in several Brazilian states has already been confirmed, but this is the first report in the State of Rio Grande do Norte. This finding highlights the risk of the carrying of emerging and re-emerging pathogens to peridomestic hosts are as, either because of the frequency of these ticks in wild environments or the presence of infected wild animals near peridomestic environments, exposing domestic dogs to parasitism by A. ovale ticks and, therefore, to agents potentially carried by this ectoparasite.
本研究旨在报告卵形硬蜱（Koch，1844）在巴西北里奥格兰德州阿波迪市犬类中的寄生情况。除了鉴定出1只卵形硬蜱雌虫和2只雄虫标本外，该动物还被5只微小牛蜱（Rhipicephalus (Boophilus) microplus）雌虫以及7只血红扇头蜱（R. sanguineus）雌虫和3只雄虫寄生。卵形硬蜱的发现证实了文献中的结果，即这些在几种野生食肉动物中被报道的蜱虫，在巴西也可感染犬类。这种蜱虫在巴西多个州的分布已经得到证实，但这是北里奥格兰德州的首次报告。这一发现凸显了向周边宿主传播新出现和再次出现病原体的风险，这是由于这些蜱虫在野生环境中的频繁出现，或者周边环境附近存在受感染的野生动物，使家犬面临被卵形硬蜱寄生的风险，因此也面临这种体外寄生虫可能携带的病原体的感染风险。
