Cell envelope preparations of Treponema hyodysenteriae (strain CN 8368) were examined using biochemical and immunochemical methods. Several major polypeptides were detected with molecular weight between 24-kDa and 45-kDa. The majority of these polypeptides were recognised by serum from a pig vaccinated with an experimental whole-cell T. hyodysenteriae vaccine and hyperimmune anti-T. hyodysenteriae rabbit sera. Immune electron microscopy confirmed that the major antigens detected were associated with the cell envelope. Triton X-100, in the presence of EDTA, completely solubilised a polypeptide with an approximate molecular weight of 36-kDa. Antibodies to this polypeptide were not absorbed by whole T. innocens cells.
