PINHEIRO, Raul Henrique da Silva et al. Nematode capilaridae in the tongue of Cerdocyon thous of free life in Brazil. Rev. Bras. Parasitol. Vet. [online]. 2018, vol.27, n.4, pp.531-544.  Epub 08-Nov-2018. ISSN 0103-846X.

Studies of helminths in road-killed wild animals are still uncommon but may provide promising results since they can identify the parasites in juvenile and adult hosts and meet the recommendations of current discussions on bioethics that prioritize alternative methods for the use of animals. This study evaluated three Cerdocyon thous individuals that were donated after dying from being run over. Two of them had small nematode adults in the epithelial and connective tissues of the tongue. The diagnosis was based on the presence of eggs, observed in histological sections, and morphological characteristics of the nematodes in the tongue. Morphologically, this nematode has a body with transverse grooves, simple mouth opening and no lips, esophagus and stichosome with stichocytes and bacillary bands along the body, which is characteristic morphology of the family Capilariidae and genus Capillaria . The presence of this nematode in the tongue of C. thous is an extremely important fact that contributes to what is known about the biodiversity of zoonotic parasites in wild canid populations. However, an explanation for these findings remains unclear because, until now, this has not been observed in the biological cycle of the species.
