Study Notes

Neisseria

The genus Neisseria includes two important human pathogens: Neisseria meningitidis and Neisseria gonorrhoeae.
Neisseria species are Gram-negative cocci.
Neisseria species are oxidase-positive.
Neisseria species produce catalase and oxidase.

Neisseria meningitidis (Meningococcus)

Neisseria meningitidis has a prominent polysaccharide capsule.
The polysaccharide capsule enhances virulence by its antiphagocytic action and induces protective antibodies.

Neisseria gonorrhoeae (Gonococcus)

Neisseria gonorrhoeae does not have a polysaccharide capsule.
Neisseria gonorrhoeae has multiple serotypes based on the antigenicity of its pilus protein.
