[Toxoplasmosis in the Congo Republic. Seroepidemiological study].
Our study group, which was composed of over 2,500 subjects, aged between 0 and 65 years, came from different regions of Congo. The samples obtained were examined for the presence of IgG and IgM against Toxoplasma gondii. IgG were detected in about 33% of children over 9 years and in about 40% of adults. A study of IgM confirmed the early contact of children with the parasite (11% of positive samples for children between 4 and 9) and that of young women (5 to 7% positivity for subjects between 15 and 30). In spite of local variations, the extremely humid climate did not allow us to detect a difference based on the origin of the samples as furthermore there seems to be an ethnic factor involved. Among the different types of professions in our sample only farmers appear to be less frequently positive. Diet, as well as contact with animals do not seem to have an influence.
