Nosocomial pneumonia due to Streptococcus pneumoniae

Nosocomial pneumonia due to Streptococcus pneumoniae is an acute bacterial infection of the lower respiratory tract that develops in hospitalized patients at least 48 hours after admission, having not been present or incubating at the time of entry This condition predominantly affects hospitalized adults with underlying comorbidities, impaired host defenses, or those requiring mechanical ventilation (ventilator-associated pneumonia), often presenting with fever, purulent sputum production, new o...

Pathophysiologically, the gram-positive diplococcus typically colonizes the nasopharynx and gains entry via microaspiration into the pulmonary parenchyma, inciting an intense alveolar inflammatory response characterized by neutrophil infiltration and exudative consolidation

This condition predominantly affects hospitalized adults with underlying comorbidities, impaired host defenses, or those requiring mechanical ventilation (ventilator-associated pneumonia), often presenting with fever, purulent sputum production, new or worsening pulmonary infiltrates on imaging, and compromised oxygenation
