title: Production and characterization of monoclonal antibodies specific for lipooligosaccharide of Serpulina hyodysenteriae.
abstract: Serpulina (Treponema) hyodysenteriae is the causative agent of swine dysentery, a contagious mucohemorrhagic disease of the colon. Diagnosis of swine dysentery is extremely difficult because of the presence of cross-reactive antibodies to the proteins of S. hyodysenteriae and Serpulina innocens, a nonpathogenic inhabitant of the porcine large intestine. Therefore, monoclonal antibodies (MAbs) against the serotype-specific lipooligosaccharide (LOS) antigens of S. hyodysenteriae were produced to rapidly differentiate S. hyodysenteriae from S. innocens. Whole-cell preparations of S. hyodysenteriae serotypes 1 through 7 were used as antigens. MAbs were characterized by an indirect enzyme-linked immunosorbent assay with whole-cell or LOS antigen and by Western blot (immunoblot) analysis with whole-cell lysates as antigen. A total of 12 LOS-specific MAbs which could identify and differentiate the seven original serotypes of S. hyodysenteriae were produced. The MAb serospecificities are as follows: MAb 9G8, serotype 1; MAb 31D9, serotype 2; MAb 7D3, serotypes 2 and 7; MAb 24B7, serotype 3; MAb 13C2, serotype 4; MAb 18E9, serotype 4; MAb 2B7, serotype 6; MAb 1D2, serotypes 2, 5, and 7; MAb 9C5, serotypes 2, 5, and 7; MAb 11C9, serotype 7; MAb 11E10, serotype 7; and MAb 6G11, serotype 7.
