[edit] Carbohydrate Name

Capsular Vi polysaccharide

[edit] Carbohydrate Class

Capsular polysaccharide

[edit] Source Microbe

Salmonella typhi

[edit] Basic Structure

The salmonella Vi Capsular polysaccharide is a linear homopolymer of α[1-->4]-O-acetyl-N-acetyl-galactosaminuronic acid

[edit] Proposed functions

It is an important virulence factor. The Vi capsule shields the bacteria against phagocytosis by its surface negative charge properties and by covering cell-envelope components sensitive to serum opsonins

[edit] Antigenic Nature used to produce antibodies

Heat killed bacteria and purified Vi polysaccharide

[edit] Carrier Name

nil

[edit] Conjugation Method

nil

[edit] Antibodies

Mab MATy-V7

[edit] Antibody type and class

IgM

[edit] Assay System

inhibition enzyme immunoassay

[edit] Cross-reactivity

This Mab was specific to Vi antigen

[edit] Proposed epitopes

N/A

[edit] Proposed Utility

This Mab was shown to be a useful serotyping agent by correct identification in slide agglutination tests of 32 clinical isolates of all the S. typhi and other serogroup D salmonellae among a total of 140 bacterial isolates representing eight different Enterobacteriaceae genera tested
