title: GALACTOSIDASE ACTION ON HUMAN BLOOD GROUP B ACTIVE ESCHERICHIA COLI AND ON RED CELL SUBSTANCES.
abstract: The blood group B specificity of Escherichia coli O(86) antigen, a B specific oligosaccharide fraction from it, and the B activity of a preparation of an "infectious mononucleosis receptor" from cattle erythrocytes are destroyed by alpha-galactosidase from the coffee bean, as demonstrated for the E. coli antigen by three methods. Blood group H(O) activity appears simultaneously. Galactose is the only hexose released from all three substances.
