Question

1. This type of enzyme allows the pathogen to destroy a specific type of antibody molecule, this activity can help the pathogen colonize tissue 2. this extracellular polysaccharide might prevent phagocytosis or complement activation 3. causes diseases by producing a massive overproduction of cytokines A. super antigen B. IgA protease C. Capsule

Answer 1

1. This type of enzyme allows the pathogen to destroy a specific type of antibody molecule, this activity can help the pathogen colonize tissue	B. IgA protease
2. this extracellular polysaccharide might prevent phagocytosis or complement activation	C. Capsule
3. causes diseases by producing a massive overproduction of cytokines	A. super antigen

1. IgA protease enzyme destroys IgA antibodies, chronic colonization could occur if anti- adhesive IgA is destroyed by this protease.

2. Capsule is an extracellular polysaccharide composed of sugar monomers that prevent phagocytosis of bacteria.

3. A superantigen causes massive activation of T cells (5–30% of all T cells), leads to overproduction of cytokines that produce systemic toxicity, and to endothelial cell destruction.
