Klebsiella pneumoniae bronchitis

*Klebsiella pneumoniae* bronchitis is a lower respiratory tract infection characterized by acute or subacute inflammation of the bronchial tree caused by the Gram-negative opportunistic bacterium *Klebsiella pneumoniae* Pathophysiologically, the bacterium colonizes and invades the mucosal lining of the bronchi, where its thick polysaccharide capsule impedes phagocytosis and incites a pronounced neutrophilic inflammatory response

*Klebsiella pneumoniae* bronchitis is a lower respiratory tract infection characterized by acute or subacute inflammation of the bronchial tree caused by the Gram-negative opportunistic bacterium *Klebsiella pneumoniae* It primarily occurs in hospitalized patients, immunocompromised individuals, elderly adults, or those with underlying chronic respiratory illnesses such as chronic obstructive pulmonary disease or bronchiectasis

It primarily occurs in hospitalized patients, immunocompromised individuals, elderly adults, or those with underlying chronic respiratory illnesses such as chronic obstructive pulmonary disease or bronchiectasis Defining clinical manifestations include persistent cough, purulent sputum production, fever, wheezing, and dyspnea, typically occurring in the absence of frank alveolar consolidation
