Haemophilus parainfluenzae bronchitis

*Haemophilus parainfluenzae* bronchitis is a lower respiratory tract infection characterized by bacterial inflammation of the bronchial mucosa caused by *Haemophilus parainfluenzae*, a Gram-negative opportunistic coccobacillus It most commonly manifests as an acute bronchitis or an acute bacterial exacerbation of chronic bronchitis in adults, particularly individuals with underlying chronic obstructive pulmonary disease, impaired mucociliary clearance, or compromised immune defenses

*Haemophilus parainfluenzae* bronchitis is a lower respiratory tract infection characterized by bacterial inflammation of the bronchial mucosa caused by *Haemophilus parainfluenzae*, a Gram-negative opportunistic coccobacillus Clinically, affected patients present with a persistent cough, increased volume or purulence of sputum, chest congestion, wheezing, and varying degrees of dyspnea

It most commonly manifests as an acute bronchitis or an acute bacterial exacerbation of chronic bronchitis in adults, particularly individuals with underlying chronic obstructive pulmonary disease, impaired mucociliary clearance, or compromised immune defenses Pathophysiologically, the organism colonizes the tracheobronchial epithelium, triggering neutrophil infiltration, mucosal edema, and hypersecretion of mucus
