Pterygodermatites (Multipectines) affinis (Jägerskiöl, 1904) (Nematoda: Rictulariidae), um parasito de Cerdocyon thous (Linnaeus, 1766) (Carnivora: Canidae) da Amazônia brasileira

Resumo

Entre os nematodas de Cerdocyon thous, o gênero Pterygodermatites é característico por apresentar projeções cuticulares ao longo do corpo, sendo citado em diferentes hospedeiros na América do Sul, porém, sem registros de sua ocorrência no Bioma Amazônia. Passível de maior exploração quanto à sua morfologia e morfometria, os nematoides colhidos de cadáveres de C. thous foram fixados e observados em microscopia de campo claro e microscopia eletrônica de varredura, revelando características compatíveis com P. (Multipectines) affinis. Com isso contribuiu com mais informações sobre a distribuição geográfica do parasito, bem como o conhecimento da fauna helmintológica de mamíferos selvagens na Amazônia brasileira.
