The O polysaccharide chain of the lipopolysaccharide from Vibrio cholerae 076 is a homopolymer of N-[(S)-(+)-2-hydroxypropionyl]-alpha-L-perosamine
Article Abstract:
Previous studies have reported that the polysaccharide (PS) portion of the lipopolysaccharide (LPS) from Vibrio cholerae 076 (076) is similar to the PS portion of LPS from V. cholerae 01 (01). This was confirmed by serological studies of LPS from 076. The sugar composition of PS from 076 was similar to that of 01, except in the configuration of L-perosamine. LPS of 076 had an L-configuration whereas a D-configuration was seen in the perosamine in the LPS of 01. Furthermore, LPS of 076 and LPS of other strains including 01 showed serological cross-reactions of the O-polysaccharides between the strains.

An immunochemical study of serological cross-reaction between lipopolysaccharides from Vibrio cholerae O22 and O139
Article Abstract:
Immunological studies of lipopolysaccharides (LPS) from Vibrio cholerae strains O139 and O22 reveal similarities in the LPS chemical structure and composition. The LPS consist of sugars such as D-glucose, D-fructose and L-glycero-D-manno-heptose. Passive hemolysis and passive hemolysis inhibition tests on the strains reveals relationships. The major O antigen of O139 is the factor common between the two strains (factor a), while the major O antigen of O22 is specific for the O22 strain (factor c).

Immunochemical characterization of an Ogawa-Inaba common antigenic determinant of Vibrio cholerae 01
Article Abstract:
An Ogawa-Inaba common antigenic determinant of Vibrio cholerae 01 is discussed. The determinant has been immunochemically characterized. Both the core and the O-specific polysaccharide are involved in a common anitigenic determinant. Thus the presence/absence of the Ogawa-specific antigenic determinant would lead to expression of two independent antigenic determinants of V. cholerae O1.
