摘要：
Serum samples from 711 sheep from 109 farms in Minas Gerais State, Brazil, were investigated for determining the Toxoplasma gondii seroprevalence using ELISA (enzyme-linked immunosorbent assay) and IFAT (indirect fluorescence antibody test). The T gondii seroprevalence was 31.1% and 43.2% by ELISA and IFAT, respectively. Among the positive ELISA sheep sera, 19% of samples contained low avidity IgG, suggesting the occurrence of the recent phase of toxoplasmosis in Minas Gerais. Animals' age, sex, breed, geographic origin and others variables associated with T gondii infection were analyzed as risk factors for toxoplasmosis but only the age was significantly associated with the parasite disease, the older animals (age over 36 months) being more frequently infected than young ones (OR = 1.45, 95% CI: 1.20 - 1.74).
