[Epidemiological study of toxoplasmosis at Kinshasa and in lower Zaire]. / Etude épidémiologique de la toxoplasmose à Kinshasa et dans le Bas-Zaïre.

An epidemiological survey of human toxoplasmosis was carried out in urban Kinshasa and in rural Kwilu-Ngongo (Bas-Zaïre). First contact with Toxoplasma gondii occurred earlier in children from Kinshasa, but adults aged over 30 were more often carriers of IgG antibodies in Kwilu-Ngongo (65.5%) compared to those in Kinshasa (50.2%). In Zaire, nutritional diet and telluric contact seem to be very important.
