[Toxoplasmosis in Niger. A serological analysis of 400 subjects].

A toxoplasmosis serological study using an indirect immunofluorescence method was made in 400 subjects in the Republic of Niger because the epidemiologic findings of this disease were very poor. Serum antitoxoplasmic antibodies were present in 18.2%. In sahelian areas prevalence of such toxoplasmic antibodies is low in the majority of studies. Analysis of seropositivity and age pointed out a late seroconversion.
