Study Notes
Neisseria Gonorrhoeae (Gonococcus)
- Lacks a polysaccharide capsule
- Has multiple serotypes based on the antigenicity of its pilus protein
- Antigenic variation in gonococcal pili occurs due to chromosomal rearrangement
- There are over 100 known serotypes
- Has three outer membrane proteins: proteins I, II, and III
- Protein II plays a role in attachment of the organism to cells
- Protein II varies antigenically
