A total of 2306 serum samples obtained from adult sheep were analysed
for Toxplasma gongii IgG antibodies by modified direct agglutination t
est and indirect immunofluorescence assay test. Similar results were o
btained with both procedures (seroprevalence of 35.27% for modified di
rect agglutination test and 33.72% for indirect immunofluorescence ass
ay test at dilution 1:80), but some differences in relation to sample
dilution were registered. All the titers assayed (dilution two-fold fr
om 1:40 to 1:320) can be used in diagnosis with both procedures, but t
iters 1:80 are recommended for screening studies in ovine flocks.
