Reports of trypanosomosis caused for salivarian trypanosomes are common in the Old World, in the New World, subtropical area of Argentina and the Pantanal, Brazil, has been reported outbreaks. The enormous antigenic variation of these parasites difficult the development of effective vacination. Infections by pathogenic trypanosomes cause diseases wich vary in severity depending on the virulence of the organism and susceptibility of the host. Strains in each species are capable of evoking a range of responses including acute, chronic and asymptomatic carrier syndromes. There are very marked differences between species and breeds of animals in their susceptibility are observed in uniform groups of animals. Two groups of twelve males Wistar rats were infected with T. evansi equine. The first stock, called stock A, was isolated in 1994 from an outbreak in horses from the Jacadigo lake, Pantanal - Brazil. The mortality recorded was 51%. The second stock, called stock B, was isolated in 1955 from a sick mare that had an abortion, distant 80 km of the outbreak. Three subgroups of four animals were infected with 5 x 10 6, 2.5 x 10 6 and 10 6 parasites on each group respectivily. The group infected with stock A demostred lower mortality rate than rats infected with stock B. In the 5th day post infection (d.p.i.) 100% of stock B infected animals died and in the stock A group only 16% died. Only in the 18 th d.p.i. 100% of stock A infected animals died. In this experiment was evidenced differences in the virulence between A and B stocks. More studies will be necessary to characterize and to know the pathogenesis of these two stocks.
