In Salmonella bacteria, pili facilitate adhesion to the intestinal wall of the host. Some strains of Salmonella also have pili that transmit genetic material (DNA) in resistant strains.2 Sources
Structure and Role of Pili in Prokaryotes - News-Medical.net
Pili are shorter and thinner than flagella. While flagella are rigid, with torque generated by the motor, pili are less rigid and straighter. Pili can be found evenly around the surface of the cell, or localized to one or both of the poles. They are typical of Gram-negative bacteria, but can be found in Gram-positive bacteria … See more
