Streptococcus pneumoniae bronchitis

*Streptococcus pneumoniae* bronchitis is a non-invasive lower respiratory tract infection characterized by acute or chronic inflammation of the tracheobronchial tree caused by the Gram-positive bacterium *Streptococcus pneumoniae* Pathophysiologically, pneumococcal colonization and adherence to the bronchial epithelium trigger an inflammatory cascade and mucosal hypersecretion without advancing to alveolar consolidation

*Streptococcus pneumoniae* bronchitis is a non-invasive lower respiratory tract infection characterized by acute or chronic inflammation of the tracheobronchial tree caused by the Gram-positive bacterium *Streptococcus pneumoniae* Clinically, it manifests as a persistent, mucopurulent productive cough accompanied by dyspnea, wheezing, and low-grade systemic inflammation

The condition predominantly affects adults with underlying cardiopulmonary diseases—such as chronic obstructive pulmonary disease—as well as pediatric populations presenting with protracted bacterial bronchitis
