Bovine trypanosomosis, Trypanosoma vivax, risk factors, Bolivia, BrazilAbstract
Trypanosoma vivax caused between 1995 and 1997 a devastating disease in Bolivian and
Brazilian Pantanals. These regions are very important beef cattle breeding in Brazil and
Bolivia. The principal clinical signs of bovine trypanosomosis in livestock were anemia,
severe leucopenia, and abortion. The purpose of the present study was to analyze the risk
factors of the natural bovine trypanosomosis in the Bolivian and Brazilian Pantanals. We
concluded that the principal risk factors related to T. vivax transmission in the Bolivian and
Brazilian Pantanals were the transportation by foot, because the conditions for acquisition or
transmission of T. vivax were greatest at the numerous resting places along the route, the use
of contaminated needles during vaccinations, and transmission by tabanids during the rainy
season. The fauna contamination should be also considered.
