Specimens of Oncicola venezuelensis (Marteau, 1977) were recovered from fragments of intestinal tissue of a female Puma concolar (Linn, 1771) found dead in Petrópolis, Rio de Janeiro in 2017. A total of 140 helminths were recovered. Five males and 5 females of the helminths were analyzed morphologically as well as 50 parasite eggs recovered in intestinal contents. Morphologically, these helminths were compatible with the genus Oncicola, because of the size and shape of the proboscis, the size and disposition of the lemnisci and the morphometry of the eggs, in which the external membrane of the shell was delicate and clear. From histopathology, the helminths were deeply embeded in the mucosa reaching up to the muscle layer. One specimen was also identified molecularly with universal primers that amplified the eukaryote region ITS1-5.8S-ITS2. The helminth showed 99% identity with the gene sequence of O. venezuelensis deposited in GenBank. It is important to emphasize, this parasite has been very little reported in the literature, which reinforces the importance of this report. |
