The polysaccharide capsule which surrounds bacterial species like Haemophilus influenzae, Streptococcus pneumoniae, Neisseria meningitidis, Salmonella typhi, is a potent virulence factor. It protects the bacterium from phagocytosis, but capsule specific antibodies plus complement binding to the capsule opsonise the organism for phagocytosis and elimination. Purified capsules elicit T-independen...
