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.
