(1) Galactoside carrier in E. coli.(2) Cell surface antigen of Brucella.(4) Cell wall protein of streptococci: antibody typing of the M-protein is important in identification of different strains of Group A streptococci (at least 55 serotypes are known). The M-protein confers anti-phagocytic properties on the cell and is present as hair-like fimbriae on the surface. M-protein is an important virulence factor, and antibodies directed against M-protein are essential for phagocytic killing of the bacteria.
