title: [The relationship between haptoglobin type and serum agglutination titers against group G streptococci with the T4-antigen in pregnant women and newborn infants].
abstract: The relationship between haptoglobin type and titer of agglutination against streptococci carrying the T4-antigen was examined in 100 pairs of sera (mother/child). In healthy pregnant women high titers were predominant in individuals of haptoglobin type 2--2. Lower titers were found in sera of women with diseases during pregnancy. In 4% of the newborns only the haptoglobin type could be recognized. In comparison of maternal and neonate titers of agglutination pointed out the antibody-like activity of haptoglobins.
