Abstract
This invention relates to the identification of Bovine Viral Diarrhea Virus group II (BVDV-II) nucleic acid sequences (e.g., gp53 sequences), to methods of using the nucleic acid sequences for detecting BVD-II virus in animal sera, to polypeptide viral antigens derived from the sequences and immunoreactive with sera from animals infected with Bovine Viral Diarrhea group II (BVD-II) virus, to polynucleotide sequences which encode these polypeptide antigens, to an expression system capable of producing the polypeptide antigens, to vaccines containing the polypeptide antigens, to methods of using the polypeptide antigens for detecting BVD-II virus antibodies in animal sera, and to antibodies directed against these polypeptide antigens.
Claims2
An immunogenic composition for generating an immune response in a cow against an infection caused by bovine viral diarrhea virus group II (BVDV-II), comprising
- a chimeric gene operatively coding for a BVDV-II gp53 polypeptide antigen, and
- a pharmacologically acceptable vehicle,
- wherein said gene is effective to express said polypeptide antigen in said cow.
