Modulating the expression of some biological membrane glycoconjugates by a Nocardia opaca fraction.
By some hemagglutination (HA) studies it was proved that NLD (the lysozyme digest fraction of Nocardia opaca) interacts with the Sendai virus envelope glycoproteic receptors, but not with those of the Beijing 353/89 H3N2) Influenza virus. Very likely the inhibition is due to the presence of some GAL lectins in NLD: The erythrocytes agglutinability (by the Sendai virus and by the Beijing 353/89 H3N2) Influenza virus is enhanced by their incubation with galactose.
