Answer

Symptoms of Campylobacter infection begin after an incubation period of up to a week. The sites of tissue injury include the jejunum, the ileum, and can extend to involve the colon and rectum. C jejuni appears to invade and destroy epithelial cells. C jejuni are attracted to mucus and fucose in bile, and the flagella may be important in both chemotaxis and adherence to epithelial cells or mucus. Adherence may also involve lipopolysaccharides or other outer membrane components. Such adherence would promote gut colonization. PEB 1 is a superficial antigen that appears to be a major adhesin and is conserved among C jejuni strains.
