Abstract

Campylobacter jejuni is a common cause of bacterial enteritis. The surface capsular polysaccharides are important for this bacterium to survive in the environment, but little is known about their involvement in bacterium–host interactions. This study showed that the C. jejuni capsular polysaccharides play an important role in adherence to and invasion of human embryonic epithelial cells. However, no significant role of capsular polysaccharides was shown in colonization of the chicken gut.
