Use of lectins to detect and differentiate subtypes of Marek's disease virus and turkey herpesvirus glycoproteins in tissue culture.
Biotinylated lectins in conjunction with an avidin-biotin-peroxidase complex were used for the first time to reveal glycoproteins in chicken and duck embryo fibroblasts infected with three prototype members of the avian herpesvirus group, Marek's disease virus serotypes 1 and 2 and turkey herpesvirus. By using a panel of 10 lectins, a pattern of reactivity emerged which was both group- and type-specific. Morphological details of the lectin-stained cells include cytoplasmic granulation, capping and bleb-like protrusions of the cell membrane. Although no antibody is necessary for the reaction, this novel approach allows specific detection of the glycan moieties of viral glycoproteins as they are synthesized during infection.
