Abstract
Vibrio parahaemolyticus Na2 and its pili were studied in relation to intestinal colonization. The isolated pili were adhesive to the intestinal epithelium. The adhesion of the organisms was blocked by masking the epithelial receptor with the purified pili, or by treating the organisms with anti-pilus antibody (Fab fraction). These results suggest that the pili of V. parahaemolyticus Na2 play an important role in the adhesion of the organisms to the rabbit intestine.
