Carbohydrate Name

Lipopolysaccharide

Carbohydrate Class

Lipopolysaccharide

Source Microbe

Vibrio cholerae 01 serogroup

Basic Structure

The O-antigen part consists of (1-->2)-α-linked 4-amino-4,6-dideoxy-D-mannose (perosamine) whose amino group is acylated with 3-deoxy-L-glycero-tetronic acid. The terminal sugar in the Inaba O-antigen has a hydroxyl at the 2' position


Proposed functions

V. cholerae lipopolysaccharide (LPS), a critical component of the outer membrane that is required for virulence, is a known target for immune responses following infection or immunization. Antibodies specific for V. cholerae LPS are correlated with protection against cholera

Antigenic Nature used to produce antibodies

Killed Vaccine consisting of V. cholerae O1 Inaba (ATCC 14033) and Ogawa (ATCC 14035) cells

Carrier Name

nil

Conjugation Method

nil

Antibodies

Mab A6

Antibody type and class

IgG3

Assay System

enzyme-linked immunosorbent assay (ELISA), immunofluorescence, Immunoelectron microscopy and the slide agglutination test

Cross-reactivity

This Mab reacted with both Inaba and Ogawa serovars (A antigen) and was specific to O1 serotype

Proposed epitopes

The epitope was named as Epitope A. Epitope A was postulated to be either the perosamine residues or the N-tetronic acid (N-3-deoxy-L-glycero-tetronic acid) side chain

Proposed Utility

This Mab produced discernible agglutination within 1 min with each of the 37 01 whole-cell suspensions tested
