A gram-negative commensal bacterium involved as a causative agent in some human diseases including endocarditis and pharyngitis.
Haemophilus parahaemolyticus is commonly present at the upper respiratory tract involved in pharyngitis and sub acute endocarditis. It is considered as natural commensal organisms of the nasopharynx in humans which can be pathogenic that occurs rarely but act as an opportunistic pathogen particularly to individual with aspiration pneumonia.
Haemophilus parahaemolyticus is implicated in various infections including endocarditis, pharyngitis, empyema in the gallbladder and cryptogenic brain abscess. It is also associated with acute respiratory distress syndrome and septic shock.
Haemophilus parahaemolyticus showed susceptibility in ceftriaxone, ampicillin, rifampin, gentamicin and ciprofloxacin and has been isolated in throat, pharynx and sputum that has a potential for causing invasive and severe diseases in humans.
