title: To the problem of toxoplasmosis in Vietnam.
abstract: The number of 259 human seria was examined for Toxoplasma gondii antibodies in 1984. Under survey were 140 persons from Duyen Thai village situated in a suburban agricultural area of Hanoi, and 119 persons from the villages of Mai Chau district in a mountainous valley near Laos border. A microreaction of complement fixation had shown higher titres in Mai Chau (24.3%) in comparison with 15.7% in Duyen Thai, using 1:16 and higher titres as significant reaction. Age distribution of antibodies revealed early infection in the childhood, as 50% of children had significant reactions in Mai Chau and 27.6% in Duyen Thai. Lately the level of antibodies was decreasing to a minimum (8%) in Duyen Thai in the age group of 30-49 years.
