Tayassu tajacu, popularly known as collared peccary, is a wildlife species found throughout the American continent, being abundant in their places of occurrence. This study aimed to describe the helminthological fauna, as well as the infection indicators, of the collared peccary (T. tajacu) coming from the Brazilian Amazon. Five adult peccaries (three males and two females) were captured in the Araguaína region, Tocantins, Brazil, with the aid of traps. The collared peccaries were reassured, chemically restrained and euthanized according to the Brazilian Good Practice Guide for Animal Euthanasy of the Federal Board of Veterinary Medicine. The species found were identified and the infection indicators were determined (infection rate, abundance, mean intensity and intensity variation). A total of 1394 helminths of nine nematode species were collected: Eucyathostomum dentatum, Cruzia brasiliensis, Monodontus semicircularis, Monodontus aguiari, Spiculopteragia tayassui, Texicospirura turki, Parabronema pecariae, Physocephalus sexalatus and Cooperia punctata. Helminths with higher percentages of infection were Physocephalus sexalatus, Parabronema pecariae and Monodontus aguiari found in 100% of the examined animals; the latter was the most abundant (164) and had a highest mean intensity (164) and total number of helminths (820). In contrast, Spiculopteragia tayassui presented lower indicators, found only one female in this study. In this studythe the first occurrence of Cruzia brasiliensis parasitizing collared peccary (T. Tajacu) in Brazil was reported, specie hitherto described and only found parasitizing domestic pigs. |
