Gonococcus does not involve –
**Core Concept**
Gonococcus, caused by the bacterium Neisseria gonorrhoeae, is a sexually transmitted infection that primarily affects the mucous membranes of the reproductive tract. The pathogenesis of gonococcus involves the bacterium's ability to adhere to and invade host cells, leading to inflammation and tissue damage.
**Why the Correct Answer is Right**
The correct answer involves understanding the pathogenesis of gonococcus. Neisseria gonorrhoeae does not typically involve the central nervous system (CNS), unlike other bacterial meningitis causes such as Neisseria meningitidis. This is due to the bacterium's inability to cross the blood-brain barrier, which protects the CNS from infection.
