*Klebsiella pneumoniae* chronic bronchitis refers to a bacterial lower respiratory tract infection in which the Gram-negative bacillus *Klebsiella pneumoniae* colonizes or actively infects the bronchial tree of individuals with preexisting chronic bronchitis or chronic obstructive pulmonary disease (COPD) Commonly encountered in the context of acute bacterial exacerbations of chronic bronchitis, it predominantly affects adult patients—frequently those with advanced age, compromised lung architec...

*Klebsiella pneumoniae* chronic bronchitis refers to a bacterial lower respiratory tract infection in which the Gram-negative bacillus *Klebsiella pneumoniae* colonizes or actively infects the bronchial tree of individuals with preexisting chronic bronchitis or chronic obstructive pulmonary disease (COPD) Pathophysiologically, pathogen proliferation triggers mucosal inflammation, impaired mucociliary clearance, and bronchial hypersecretion, clinically manifesting as acute worsening of dyspnea, i...

Commonly encountered in the context of acute bacterial exacerbations of chronic bronchitis, it predominantly affects adult patients—frequently those with advanced age, compromised lung architecture, repeated antibiotic exposure, or underlying comorbidities such as diabetes and alcohol use disorder
