| Abstract: | Pregnant and parturient women have been examined in different regions of the USSR: Moscow, the Turkmen SSR, the Azerbaijan SSR and the Uzbek SSR. Altogether 720 placental sera and 522 funic sera have been checked for the presence of antibodies to diphtheria and tetanus toxoids in the passive hemagglutination test. Considerable groups of women with the insufficient level of immunity to diphtheria (40-66%) and tetanus (42.1-58.8%) have been revealed in different republics. Among women over 70 years the percentage of persons with the absence of antibodies or having low antibody titers has proved to be even higher. The comparative analysis of antibody titers has shown a correlation between antibody titers in mothers and newborn infants in 83.6% of cases for diphtheria toxoid and in 72.9% of cases for tetanus toxoid. These data show that among parturient women and newborn infants large groups remain unprotected against diphtheria and tetanus, which indicates the necessity of correcting the immune status of women of the productive age. |
