title: Autoinducer-2 production in Campylobacter jejuni contributes to chicken colonization.
abstract: Inactivation of luxS, encoding an AI-2 biosynthesis enzyme, in Campylobacter jejuni strain 81-176 significantly reduced colonization of the chick lower gastrointestinal tract, chemotaxis toward organic acids, and in vitro adherence to LMH chicken hepatoma cells. Thus, AI-2 production in C. jejuni contributes to host colonization and interactions with epithelial cells.
