ResumoA study on equine theileriosis was carried out in the southern region of the Brazilian state of Rio Grande do Sul (RS).Blood samples were collected from 113 mares from an equine breeding farm located in the city of Bagé, latitude 31º30' S and a longitude of 54Ú10' W. The serological testing was carried out with the use of indirect fluorescence test (IFAT) and compared with Nested Polimerase Chain Reaction (nPCR).Among the sera collected from 118 horses, 25 were found positive to Theileria equi by the IFAT, while by nPCR 17 positive for T. equi was observed, corresponding to a frequency of 22.1% and 15.0%, respectively.The racial analysis showed 15.05% ( 14) thoroughbred and 55% (11) Crioulo breed horses to be positive by IFAT.
