Question

Some strains of Escherichia coli bacteria use a syringe-like mechanism to inject bacterial proteins into the host cell. Some of these proteins become receptors in the host cell's membrane, which help the bacterium bind firmly to the cell's surface. The proteins also trigger a pathway that causes the host cell to form a "pedestal" for the bacterium. Which VF allows E.coli to accomplish this infection strategy?
A. Enterotoxins
B. flagella (H antigen)
C. Type III Secretion system
D. capsule (K antigen)
