The sugar composition of the polysaccharide portion of lipopolysaccharides (LPS) was determined for 42 serovars of non-O1 Vibrio cholerae, i.e., from serogroups O2 to O41, O44, and O68. On the basis of their compositional sugar pattern, they were classified into 24 chemotypes. 2-Keto-3-deoxyoctonate (KDO) was totally undetectable by the conventional color test (Weissbach's reaction) under the conventional hydrolysis conditions. Instead, a kind of KDO-like substance, which was positive in the reaction but not identical to KDO, was found in serogroup O19. Fructose, a characteristic sugar constituent of O1 V. cholerae LPS, was found in 33 serogroups but was absent from nine serogroups, approximately 20% of the members of this group so far examined.
