Abstract
A purified fibronectin receptor polysaccharide derived from Staphylococcus aureus is useful as an antigen for diagnostic tests and the preparation of monoclonal antibodies. The fibronectin receptor polysaccharide is prepared by gently removing expresed material, including the polysaccharide, from the cell surfaces of the S. aureus without killing the cells followed by purification. Monoclonal antibodies directed against the polysaccharide can be used in methods of preventing or treating S. aureus infections by administering the monoclonal antibodies to animals.
