ANTIGENICITY

• The complex antigenic structure includes a capsular polypeptide, a somatic protein and a somatic polysaccharide antigen.
• The capsule contains poly-d-glutamic acid, which is only detectable in virulent strains, having antiphagocytic property.
• The somatic protein is protective antigen present in the edema fluid.
