It primarily involves the tracheobronchial tree in adults and is frequently driven by nontypeable (unencapsulated) *H. influenzae* strains

It primarily involves the tracheobronchial tree in adults and is frequently driven by nontypeable (unencapsulated) *H. influenzae* strains, often presenting as an acute infection or an acute bacterial exacerbation of chronic bronchitis in individuals with underlying pulmonary disease such as chronic obstructive pulmonary disease (COPD) or bronchiectasis

Pathophysiologically, the organism adheres to damaged respiratory epithelium and evades mucociliary clearance, resulting in mucosal inflammation, hypersecretion, persistent cough, purulent sputum production, and dyspnea
