First occurrence of Amblyomma ovale in the State of Rio Grande do Norte, Brazil.

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.
