| Abstract: | The content of antituberculosis antibodies in the blood of neonates was studied with the aid of passive hemagglutination test (PHT) after Boiden and in the PHT modified after Middlebrook-Dubot. The use of a complex antigen from the BCG vaccine in the PHT proved to possess the greatest prospects; antituberculosis humoral antibodies were detected at the time of birth in 48.5% of the children. A total of 322 neonates, including 167 neonates born of mothers with late toxemia of pregnancy, were examined. With the given complication of pregnancy there was revealed a disturbance of the transplacental transmission of antituberculosis antibodies, this being explaining by the destructive-sclerotic changes in the placental tissue in marked toxemia of pregnancy. |
