[An epidemic of familial toxoplasmosis (author's transl)].

After observation of choroiditis of toxoplasmic nature in a member of a rural family, the authors have led a clinical and serological study on other five members of the household. Three of five had antibody titers and two of these demonstrated antibody titers consistent with recent toxoplasmic infection; one of these members manifested asymptomatic choroiditis. Therefore, it would be interesting to carry out a clinical and serological study on relatives of patient with toxoplasmosis.
