Of the 4,048 patients, 2,765 had negative tests for toxoplasma antibodies and were at risk; 6 of these tests converted to positive during pregnancy, and 2 of the 6 transmitted toxoplasmosis to their infants. Of the 1,283 patients who had positive tests for Toxoplasma antibodies on prenatal blood specimens, 17 showed a substantial rise in titer during pregnancy, and 1 of these transmitted toxoplasmosis to her infant. The study population included 758 Negroes, 70 Orientals, 403 white patients born in Puerto Rico, and 2,817 whites born elsewhere. All 6 of the patients whose tests converted, 15 of the 17 who showed a rise in titer, and all 3 infected infants were white.
