Sera from 7,506 patients were examined for toxoplasma antibodies by the Sabin-Feldman dye test and the results were analyzed according to antibody level, by reason for referral, age and sex. Low antibody levels (less than 1:256) were found in 24.7% and significant titers (greater than or equal to 1:256), in 9.96%. The highest prevalence of significant antibody titers was in patients with lymphadenopathy (15.4%). The prevalence of significant titers was high in the age range of 5 to 19 years, whereas the prevalence of low titers rose with age. Toxoplasma antibodies were found in 29% of a control group of 554 apparently healthy adult women, but only in 2.7% was the titer significant.
