[The immune response of the fetus in the diagnosis of intrauterine infections: IgM and IgA concentrations in the umbilical cord blood and titers of rubella and cytomegalic virus antibodies].

Two serological methods, hemagglutination and complement fixation, have been used respectively to determine HAI titers to rubella virus and C fixing antibodies to cytomegalovirus in cord blood of newborn infants delivered in Turin from August 1973 to April 1974. Sera have been divided according to antibody titer and aspecific IgM and IgA concentrations. By statistical analysis we observed a highly significant association between both IgM and IgA concentration and antibody titers to rubella virus.
