title: Monoclonal antibodies to a 16-kDa antigen of Serpulina (Treponema) hyodysenteriae.
abstract: Monoclonal antibodies (MAbs) were produced to an outer-envelope preparation from Serpulina (Treponema) hyodysenteriae, the aetiological agent of swine dysentery. Three MAbs (isotype IgG1) were obtained. All three recognised a 16-kDa antigen that was common to most strains of S. hyodysenteriae of different serotypes but was absent from nonpathogenic, porcine intestinal spirochaetes. Immunofluorescence and immunogold labelling studies showed that the 16-kDa antigen was exposed on the surface of intact spirochaetes. The MAbs agglutinated freshly grown cultures of spirochaetes and inhibited growth of S. hyodysenteriae strains in vitro.
