Question

Shigella and Rickettsiae Pathogenesis

Accepted Answer

Shigella flexneri | Rickettsiae ↓Actin and contractile system of host cell to spread their infection↓Mucosal invasion is by entering M cells in Peyer's patches↓Escape the phagosome by using actin rockets to spread laterally to other epithelial cells Actin and contractile system → M cells in Peyer's patches → actin rockets
