Fauna helmintológica de catetos (Tayassu tajacu - Linnaeus, 1758) procedentes da Amazônia Brasileira e suas implicações para a criação comercial

Abstract

Tayassu tajacu, popularly known as collared peccary, is a wild species found from the southern U.S. to northern Argentina and is abundantly found in Brazil. Its main feature is the "collar" of white bristle around the neck. They are omnivores and commonly consumed as a source of protein for coastal and indigenous populations. Their meat is highly prized in large urban centers in Brazil and abroad, and his leather used for the manufacture of fine items like gloves and bags. This makes it increased the number of commercial breeding these animals. Works with collared peccary parasites consists of description or redescription species, however, knowledge of infection indicators in addition to the parasite species, allows a better understanding of the relations between them and their hosts. Mammals present themselves parasitized a greater amount by nematodes that trematodes or cestodes, these being sometimes not observed. Have been reported parasitizing collared peccary the following species: Monodontus semicircularis, Monodontus Aguiari, Eucyathostomum dentatum, Dirofilaria acutiuscula, Texicospirura turki, Gongylonema baylisi, Gongylonema pulchrum, Parabronema pecariae, Parostertagia heterospiculum, Physocephalus sexalatus, Trichuris sp, Capillaria hepatica, Ascarops strongylina, Cooperia punctata, Cooperia spatulata, Oesophagostomum dentatum, Nematodirus molini, Trichostrongylus axei, Trichostrongylus colubriformis, Spiculopteragia tayassui, Strongyloides ransomi, Macracanthorhyncus hirudinaceus, Metastrongylus salmi, Fascioloides magna, Moniezia benedeni, Stichorchis giganteus. Knowledge of collared peccary helminth parasites is fundamental to the development of an adequate health management for the prevention and treatment of helminthic infections, aiding the expansion of its captive breeding. This study aimed know the helminthological fauna, as well as indicators of infection of collared peccary (T. tajacu) coming from the Brazilian Amazon. Five adult animals were captured in the Araguaína City, Tocantins State. The collared peccaries were euthanized and necropsied on the field with the opening and wash of each anatomical segment of the digestive tract, and was made an observation of the trachea, heart, lung, kidneys and subcutaneous tissue. The contents of the resulting washes were fixed in a solution of Railliet & Henry to species identification and determination of helminth infection indicators. Were collected 1394 helminths of the five collared peccaries, being nine species of nematodes: Eucyathostomum dentatum, Cruzia brasiliensis, Monodontus semicircularis, Monodontus aguiari, Spiculopteragia tayassui, Texiscospirura turki, Parabronema pecariae, Physocephalus sexalatus, Cooperia punctata.
