What are the virulence factors of Neisseria gonorrhea?
Virulence factors. pili extend beyond the outer membrane and are Neisseria’s most important virulence factor. They are essential for adhesion to mucosal surfaces and inhibit neutrophil killing. The outer membrane is composed of phospholipids and other outer membrane proteins. These proteins facilitate adhesion and promote invasion.

The genus Neisseria contains two important human pathogens, N. gonorrhoeae and N. meningitidis . N. gonorrhoeae causes gonorrhea, and N. meningitidis is the cause of meningococcal meningitis. N. gonorrhoeae infections have a high prevalence and low mortality, whereas N. meningitidis infections have a low prevalence and high mortality.
