Carbohydrate Name

Capsular polysaccharide

Carbohydrate Class

Capsular polysaccharide

Source Microbe

Neisseria meningitidis group B

Basic Structure

It consists of a homopolymer of α(2-->8)-linked sialic acid residues

Proposed functions

It is an important virulence factor

Antigenic Nature used to produce antibodies

Infected patient

Carrier Name

nil

Conjugation Method

nil

Antibodies

Mab LOG

Antibody type and class

IgM

Assay System

ELISA, Rat protection assay

Cross-reactivity

This Mab cross-reacts with E. coli K1 polysaccharide but does not react with E. coli K92, group A and group C polysaccharides of Neisseria meningitidis. This Mab also reacts with N-propionylated group B polysaccharide

Proposed epitopes

The epitope consisted of α2-8 linked N-acetylneuraminic acid acid residues

Proposed Utility

This antibody protected infant rats from bacteremia caused by Escherichia coli K1
