The rates oblalned for seropositivity by IFA test in animals at pasture and vaccinated, at pasture and non-vaccinated, at haused and non-vaccinated were 46.15%, 31.48% and 12.19% respectively. The rales obtained lor piroplasm carrier by microscopical examination were 23.07%, 25.92% and 3.65% respectively.
