RESUMO
Since little information is available on the epizootiological status of Trypanosoma evansi in South America and particularly Brazil, we evaluated equine serum samples collected in 1993, 1994, 1995 and 1997 for the presence of antibodies against this trypanosome species. Our study shows corroborative evidence about the correlation among high T. evansi seroprevalence and the rainy season in the Pantanal, Brazil. The higher seroprevalence was 79.2 (por cento) in horses from a ranch located in the Nhecolândia sub-region in 1994 and the lower 5.8 (por cento) in animals from the same ranch in 1997. No seroprevalence was found in 1993. The possible re-introduction of T. evansi in the region as well as the relationship among our results with the outbreaks reported in 1994, are briefly discussed.
