Neisseria meningitidis capsular polysaccharide A (Serogroup A CPS)

Target
Serogroup A CPS
Molecular classification
Polysaccharide, Capsular Polysaccharide
01

Overview

Neisseria meningitidis capsular polysaccharide A is the primary surface carbohydrate antigen of N. meningitidis serogroup A, a major cause of epidemic bacterial meningitis worldwide. The capsule is a key virulence factor, enabling the bacterium to evade host immune responses and survive in the bloodstream by resisting complement-mediated killing and phagocytosis.
