a) a micrograph showing nonencapsulated cells as blue ovals on a light background. Encapsulated cells have a thick clear ring around the blue cells. B) Antibodies on phagocytic cells bind to antigens on the bacterial cell. Capsules on the bacterial cell cover the antigen and prevent the antibody from binding to the antigen. C) A bacterial cell is releasing small donts labeled proteases that are breaking down an antibody.
