TAENIA OVIS ANTIGENS AND VACCINES

摘要

This invention relates to polypeptide antigens of T.ovis suitable for use in vaccines to protect ruminants against infection by cestode parasites. The antigens are preferably obtained by expression of DNA coding therefor in a recombinant host cell. Aspects of the invention include DNA encoding the antigens, vectors containing the DNA and hosts which express the antigens. The invention also provides antibody and DNA probes for use in identifying protective antigens of cestode parasites other than T.ovis.
