H.influenzae causes meningitis by spreading via lymphatics after nasopharyngeal colonization, while N.meningitidis reaches the meninges through the bloodstream and the choroid plexus.
H.influenzae menenjitinde nazofarengeal kolonizasyondan sonra lenfatiklere yayılarak meninksleri etkiler; N.meningitidis ise nazofarengeal kolonizasyondan sonra kan yoluyla koroit pleksusa ve oradan meninkslere ulaşır.
