In all samples of DNA extracted from blood of horses the occurrence of infection by T. equi and B. caballi were investigated by PCR. In the serum samples, was assessed by ELISA, the occurrence of anti T. equi, B. caballi and Borrelia spp. The occurrence of Amblyomma sculptum, Dermacentor nitens and Rhipicephalus (Boophillus) microplus was assessed at different levels of infestation. From the analyzed serum, 82.07% (n = 389/474) were considered positive for T. equi, and a higher prevalence was observed in horses from the ?Coudelaria do Rinc?o?, in Rio Grande do Sul state (87.33%, n = 262/300). In horses kept at the Agulhas Negras Military Academy, in Rio de Janeiro state, a prevalence of 72.99% (n = 127/174) was observed. Multivariate analysis showed that the factor ?origin? of the horses stabled at Coudelaria do Rinc?o was the most influential factor associated to seropositivity of animals (p
