Cell Wall Components and Antigenic Properties

◗ Antigenic properties

Three types of antigens are present in anthrax bacillus. These are:

Capsular antigen: Capsular antigen is present in virulentcapsulated strains of B. anthracis. Antibodies against capsular antigen are not protective.

Cell wall antigen: Cell wall antigen is present in the cellwall and is made up of N-acetylglucosamine and D-galactose. It cross-reacts with blood group A antigen and with capsular polysaccharide of type 14 Pneumococcus. The antibody against the cell wall antigen is not protective.

Somatic antigen: Somatic antigen is a heat-labile protein present in bacterial body. It stimulates immune system to produce antibodies, which are protective in nature.
