title: Detection of antibodies to Toxoplasma gondii in stillborn piglets in Argentina.
abstract: Fetal fluids of 738 stillborn piglets from three swine farms in Argentina were examined for antibodies to Toxoplasma gondii. Antibodies were detected in 15 samples at a 1:20 dilution in the indirect fluorescent antibody test and 10 samples were positive in the modified agglutination test (MAT) at a dilution of 1:25; four of these samples had a MAT titer of > or = 1:100. This survey indicates a low rate of congenital T. gondii infection in stillborn pigs in Argentina.
