Purification and characterization of pili isolated from Vibrio parahaemolyticus Na2

Abstract

Pili from Vibrio parahaemolyticus Na2 isolated from a patient with diarrhea were purified and characterized. The organisms were hemagglutinative, but the purified pili were not. Na2 pili were physicochemically and immunologically quite different from the previously described V. parahaemolyticus Ha7 pili. Nevertheless, there was a high degree of homology between their N-terminal amino acid sequences.
