[The results of a serological examination of the population for toxoplasmosis and the estimated incidences of congenital toxoplasmosis in 2 foci in Uzbekistan].

Enzyme immunoassay was used in screening for toxoplasmosis of 500 residents of the town of Ghulistan and of 1074 residents of the town of Shavat in the Khorezm district of Uzbekistan. All the examinees were aged 15 to 40. The share of seropositive subjects in Ghulistan was 24.6%, that in Shavat 14.6%, the toxoplasmosis loimopotentials were 0.87 and 0.62%, respectively. The predicted parameters were as follows: new cases of toxoplasmosis among pregnant women were 4.9% in Ghulistan and 3.9% in Shavat, the incidence of congenital condition 1.7 and 1.3%, respectively, the incidence of manifest congenital toxoplasmosis 0.6 and 0.4%, respectively. The presence of a cat in the house was associated with higher share of seropositive subjects in the town of Shavat as against Ghulistan. An urban focus (Ghulistan) appeared more intensive as against a rural type focus (Shavat) at the expense of a higher intensity of the xenotropic route of the agent transmission.
