Quizplus · Accepted Answer

The capsule is the most significant virulence factor associated with Haemophilus spp. It helps the organism to resist phagocytosis and complement-mediated lysis, thus allowing it to invade tissues and cause disease. Pili are important in initial attachment to host cells, IgA protease may aid in colonization, and enterotoxin can cause diarrhea but none of them plays as significant a role as the capsule in invasiveness.
