Which statement about Neisseria meningitidis meningitis is true?

Explanation:
Neisseria meningitidis meningitis presents as a Gram-negative diplococcus with a capsule. The capsule is a key virulence factor that helps the bacteria resist phagocytosis, allowing colonization in the nasopharynx to progress to bloodstream invasion and meningitis. It spreads mainly through respiratory droplets and close person-to-person contact, not via the fecal-oral route. While conjunctival infection can occur, the disease is not primarily conjunctivitis. So the statement that best fits the biology of this organism is that it is a Gram-negative diplococcus with a capsule.
