  • Title: Demonstration of bovine virus diarrhoea virus antigen in formalin fixed, paraffin embedded tissue using a streptavidin/biotin technique.

    Abstract:
    The detection of bovine virus diarrhoea virus (BVDV) antigen in sections from formalin fixed, paraffin embedded tissue is described. Pre-digestion of the sections with 0.02 per cent protease XIV for 18 hours at 4 degrees C is necessary to unmask formalin fixed antigen. A hyperimmune antiserum prepared in a pig, using a combination of BVDV and hog cholera virus inoculations, linked to a biotinylated anti-pig/streptavidin peroxidase detection system demonstrated antigen in a wide range of tissues from cases of mucosal disease and persistently viraemic animals. The inclusion of a monoclonal anti-pig immunoglobulin linked to a biotinylated anti-mouse/streptavidin peroxidase detection system greatly reduced non-specific staining.
