-->Immunoglobulin A (IgA) is associated with immunological protection of the host at the epithelial boundary. An IgA protease has the ability to breakdown IgA and thereby act as a virulence mechanism enabling the bacterium to invade the host through an unprotected epithelial boundary. Because IgA is an antibody associated with the humoral (specific) arm of the immune system, IgA protease allows the bacterium the ability to evade the specific humoral immunity of the host.
