[Seroepidemiology of toxoplasmosis in pregnant women and neonatal infants].

A serological screening among pregnant females for toxoplasmosis in the Belgorod Region has shown a rise in the incidence of this infection in them during seven years (1996-2002). There is also a more than 2-fold increase in the rate of Toxoplasma infection by the second trimester. This increases a risk for fetal congenital malformations and the severity of neonatal congenital malformations.

[Use of a helminthic indicator of soil to determine the frequency of toxoplasmosis among pregnant women].

Studies have ascertained the high dissemination of the soil with helminthic eggs and cysts of intestinal pathogenic protozoa (Lamblia, Toxoplasma, etc.) in some districts of the Belgorod Region. Comparing these data with the morbidity rates in pregnant females with toxoplasmosis shows a direct high correlation of the above indicators.
