The serum samples were submitted to the indirect fluoresccence antibody test, resulting in 32,34% of serum-positives. The rate of serum-reagents in each region was, Norte of Parana 50,77%, New Northen Paraná 32,50%, West of Paraná 1 7,38%, Central Region of Paraná 15,38%, South of Mato Grosso do Sul, 30,77% (titre greater or equal to 1.64). According to these results, it must be necessary to know the main source of infection and ways of Toxoplasma gondii transmission in beef cattle.
