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.
