First Report of Subulura Sp. (Ascaridoidea, Subuluridae
First report of Subulura sp. (Ascaridoidea, Subuluridae) parasitizing Cerdocyon thous (Carnivora, Canidae) in a fragment of Atlantic forest in the state of Rio de Janeiro, Brazil Luís Cláudio Muniz-Pereira1,3, Fabiano Matos Vieira1,3, Cecília Bueno1, and Paula Araujo Gonçalves1,2 1Laboratório de Helmintos Parasitos de Vertebrados (LHPV), Instituto Oswaldo Cruz (IOC), FIOCRUZ, Av.

However, the parasitism by species of this genus in wild carnivorous mammals can still be considered scarce in Brazil. The current study aims to report for the first time the parasitism by Subulura in a wild canid in Brazil. One specimen of Cerdocyon thous (Carnivora, Canidae) road killed in a stretch of BR-040 highway, near to municipality of Petrópolis (22º 30' 18" S, 43º 10' 43" W), in the state of Rio de Janeiro, Brazil, was analyzed for helminth. Nematodes were collected in small intestine, fixed in cold 4% formalin by 15 days and stored in 70°GL ethanol. For identification, the nematodes were cleared in Amann’s lactofenol and mounted in temporary slides, for microscopic identification. The specimens of nematodes analyzed in the current study were identified as Subulura because they had hexagonal buccal opening located dorsoventrally, with three lips; well developed sclerotized and thickly walled buccal capsule; anterior end of oesophagus prolonged into three sclerotized small teeth; oesophagus with posterior bulb; lateral alae present; and male with caudal sucker.
