Haemophilus

 [he-mof´ĭ-lus]
a genus of hemophilic gram-negative bacteria. H. aphro´philus, H. parainfluen´zae, and H. paraphro´-philus are part of the normal oral flora and are occasionally associated with endocarditis. Pathogenic species include H. aegyp´tius, the cause of pinkeye (acute contagious conjunctivitis); H. ducrey´i, the cause of chancroid; and H. influen´zae, a species once thought to cause epidemic influenza. A species formerly called H. vagina´lis is now called Gardnerella vaginalis. H. influenzae type b, rather than causing influenza, can cause meningitis, pneumonia, and serious throat and ear infections, particularly in children under the age of five years; vaccination against it is recommended for all children.

Haemophilus

(hē-mof'i-lŭs), Avoid the misspelling Hemophilus.
A genus of aerobic to facultatively anaerobic, nonmotile bacteria (family Brucellaceae) containing minute, gram-negative, rod-shaped cells that sometimes form threads and are pleomorphic. These organisms are strictly parasitic, growing best, or only, on media containing blood. They may or may not be pathogenic. They occur in various lesions and secretions, as well as in normal respiratory tracts, of vertebrates. The type species is Haemophilus influenzae.
