Pili of a Vibrio cholerae O139

Abstract

The pili of a strain of Vibrio cholerae O139 were purified and characterized. They were morphologically, electrophoretically and immunologically indistinguishable from the pili with 16 kDa subunit protein of V. cholerae O1. All 22 strains of V. cholerae O139 examined possessed the pili. The pili were different in hemagglutination inhibition pattern from V. cholerae O1 16K pili
