Abstract

The bovine tripanosomiasis by Trypanosoma vivax was reported for the first time in Brazil by Shaw & Lainson, in 1972, in Pará. Recently it has been reported in several areas of the Pantanal Mato-Grossense Region. The objective of the present paper was to report, for the first time, the occurrence of T. vivax in the State of Tocantins, in a Brahman herd of 250 animals, which had been introduced into a property in the municipality of Formoso do Araguaia, coming from São Paulo. From animals presenting signs of weakness, 9 was randomly chosen for detailed clinical assessment and laboratory exams such as blood smears and hematocrit. These animals presented weigh loss, edema, fever and mucous membrane paleness. The microscopic smear examination revealed high parasitemias for T. vivax in samples of three animals, with the packet cell volumes ranging between 15 and 20%. The herd history, the ecosystem of the area and the results of the clinical and laboratory exams confirmed the occurrence of an outbreak of trypanosomiasis by T. vivax in a bovine herd in the State of Tocantins. KEY WORDS: Trypanosoma vivax, bovine trypanosomiasis, Tocantins, epidemiology.
