Pili: Attaches bacterium to respiratory tract cells. Acts antigenic against the body’s immune system.

Diseases: Meningococcal - Meningitis, meningococcemia

Transmission: Respiratory tract

Virulence factors of Neisseria gonorrhea :

Pili: Complex gene codes for hypervariable genomes and antigenic against antibodies

Protein porins of outer membrane: Two protein complexes – Por A and Por B – facilitates invasion of epithelial cells
