Vibrio cholerae adherence to and colonization in the small intestine are essential step in the pathogenesis of cholera. At least one type of pili, known as TcpA, is required for the colonization process. This paper reports the electron microscopic evidence showing that V. cholerae 01 and 0139 serogroups can express at least 4 types of pili when incubated at 28℃ on AKI agar or CFA (pH6.8). Among the four types, three can be expressed by classical and El Tor strains of Vibrio cholerae 01: TcpA pili are peritrichous,being 7-8nm in diameter, 5-10μm in length, and form bundles of parallel undulating filaments of 0.5-0.8 μm wide and 10-15μm long; Type B are 3-4nm in diameter, up to 2μm long, and of wavy morphology; Type C are 7-8nm wide and 0.5-0.8μm long.
