Haemophilus spp. are small, pleomorphic, nonmotile, nonsporing Gram-negative rods or coccobacilli. They are aerobic and facultatively anaerobic. Growth is often enhanced by the addition of 5-10% carbon dioxide to the incubation atmosphere. The oxidase and catalase reactions vary among the species Haemophilus is a genus of Gram-negative, pleomorphic, coccobacilli bacteria belonging to the family Pasteurellaceae. While Haemophilus bacteria are typically small coccobacilli, they are categorized as pleomorphic bacteria because of the wide range of shapes they occasionally assume. These organisms inhabit the mucous membranes of the upper respiratory tract, mouth, vagina, and intestinal tract Haemophilus influenzae was isolated in pure or predominant culture from genital specimens from nine females and two males. Four of the females had vaginitis, two had IUD-related endometritis, one had an incomplete septic abortion, and one had probable urethral syndrome. Two males had urethritis Haemophilus influenzae is a Gram-negative, facultatively anaerobic coccobacillus, which can cause acute bronchitis and exacerbations of chronic obstructive pulmonary disease, as well as meningitis.

Haemophilus influenzae is a fastidious facultatively anaerobic Gram-negative bacterium that causes a range of human infections including otitis media, meningitis, epiglottitis and pneumonia [1,2]. H. influenzae lacks all enzymes in the biosynthetic pathway for the porphyrin ring, and as a result is unable to synthesize protoporphyrin IX (PPIX), the immediate precursor of heme In Haemophilus. All Haemophilus are gram-negative, aerobic or facultative anaerobic and nonmotile and require a growth factor that is found in blood.
