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.

本文通过电子显微镜对01群霍乱弧菌古典生物型和El Tor生物型以及0139群霍乱弧菌研究发现，在培养基AKI和CFA(pH6.8)28℃培养条件下，01群EVC和CVC均可产生TcpA，B型和C型菌毛；0139群霍乱弧菌可产生TcpA和B型菌毛，与01群一致。

Results The neurological defects score was singificiant lower in D group (41.50±8.18) than that in group A(82.20±8.08), B(63.60±6.22) and C (61.00±6.58)(all P.01). Compared with groups A, C, group D showed that the cellular nucleus was shrinkaged slightly, the gap of cells was nomal roughly and the degree of rarefaction in neurofibra net was not serious under the light microscope. Under the electron microscope, the neuron was degenerated, the cellular membrane was integrated and the plastosome was swelled lightly in the group D. The physiological demage were slighter in D group.
