Abstract

Haemophilus influenzae is a Gram-negative, strict human pathogen that can colonize hosts in an asymptomatic manner or can cause invasive disease. To persist in the host, the organism utilizes many virulence factors that are regulated in a complex manner. Virulence factors include the polysaccharide capsule of encapsulated strains, lipooligosaccharide extending from the cell membrane, and many proteins involved in adhesion of the bacterium to respiratory epithelial cells. In this review, we describe the major mechanisms of virulence and how they contribute to colonization and invasive disease.
