    The species
    Haemophilus influenzae
    belongs to the genus Haemophilus and the family Pasteurellaceae.
    H influenzae
    are small, nonmotile, nonspore forming, Gram-negative, pleomorphic rods that range in shape from coccobacilli to long filaments. They require X and V factors (hemin and NAD, respectively) for aerobic growth, and may be facultatively anaerobic (

    are classified into six antigenically distinct serotypes (a–f), and have a clonal population structure with two major global subdivisions (I and II) (

    ). Nonencapsulated
    H. infuenzae
    (NCHi) appear to have a nonclonal population composition, but a broader analysis of NCHi in the future may reveal that the population is not so distinct from encapsulated
    H influenzae
    (

    ). Both encapsulated
    H influenzae
    and NCHi exhibit wide genetic diversity (
