Incidence of Toxoplasma Antibodies in Ugandans with special reference to Cardiomyopathy.

Abstract The incidence of toxoplasma antibodies was investigated in 4 groups of Ugandans: blood donors, and patients with endomyocardial fibrosis, congestive cardiomyopathy and rheumatic heart disease. Negative results were obtained in all but one of 38 heart patients known to be under 20 years old, and positive results among adults in 15·8% of the endomyocardial fibrosis group, 34·4% of the cardiomyopathy group, and 38·7% of the rheumatic heart group. In the last 2 groups 60·9% of males and 22·5% of females were positive. Antibodies were present in 11·7% of blood donors aged 15·25.
