Question 10

Type III secretion system:

2) S. typhi
3) Y. pestis
4) Shigella
5) EPEC

Answer 10

1) Induce phagocytosis by enterocytes and multiply in phagocytic vesicles. Induce apoptosis of macrophage.
2) Enable survival inside the phagocytic vacuole of macrophages. But do NOT cause apoptosis of macrophage
3) Prevent phagocytosis by neutrophils.
4) Induce phagocytosis of enterocytes at the basolateral surface
5) Transport bacterial protein into enterocyte –> forms a pedistal for itself –> microvilli disappear
