The proteins of the outer membrane of virulent and avirulent S. sonnei phase I strains were characterized by SDS-polyacrylamide gel electrophoresis and their molecular weights were determined. Significant quantitative differences were found in composition of the outer membrane proteins between virulent and avirulent strains. These differences were confirmed in electrofocusing experiments and disc-crossed immunoelectrophoresis.
