Research Abstract

The immunoglobulin G Fc receptor was demonstrated for the first time on the most immunogenic strain of the genus Erysipelothrix selected from Japanese isolates. The receptor is a protein of 65kDa and commonly found in the strains of the genus Erysipelothrix. Protection tests in mice actively immnunized with the purified antigen of the receptor and passively immunized with mouse monoclonal antibody (Mab) against the receptor demonstrated that it was a protective antigen. These results indicated that the receptor is useful as an immunogenic component of the inactivated vaccine. Enzyme-linked immunosorbent assay (ELISA) using the receptor antigen purified by the affinity chromatography with the Mab was highly sensitive and specific. The ELISA demonstrated its usefulness for the diagnosis of erysipelas in swine by determining the antibody titer.
These results are not only useful for the diagnosis and prevention of swine erysipelas, but also important findings in microbilogy and immunology.
