Sero-epidemiology of toxoplasmosis in Gezira, Sudan.

386 blood samples from residents of Gezira Province, Sudan were tested by a latex agglutination test for toxoplasmosis. 41.7% of the sample were found positive with antibody titres of greater than or equal to 1/64. Females aged 20-49 years had a significantly higher prevalence rate than males of the same age. No correlation was found between seropositivity and history of contact with domestic cats or between seropositivity and rural versus urban residence. The findings of this study and the known food habits of the study population suggest ingestion of Toxoplasma cysts in meat to be the main mode of transmission of the disease.
