Staphylococcus nosocomial pneumonia

Staphylococcus nosocomial pneumonia is an acute lower respiratory tract infection caused by *Staphylococcus* species—predominantly methicillin-susceptible or methicillin-resistant *Staphylococcus aureus*—that develops 48 hours or more following hospital admission Clinically, it is characterized by new or progressive pulmonary infiltrates on chest imaging accompanied by fever, purulent sputum production, leukocytosis, and worsening respiratory failure, often carrying high morbidity due to necroti...

Staphylococcus nosocomial pneumonia is an acute lower respiratory tract infection caused by *Staphylococcus* species—predominantly methicillin-susceptible or methicillin-resistant *Staphylococcus aureus*—that develops 48 hours or more following hospital admission This condition primarily affects hospitalized individuals, particularly critically ill, mechanically ventilated, or postoperative patients, as well as those with impaired airway reflexes

Pathophysiologically, it typically arises from microaspiration of colonized oropharyngeal secretions into the pulmonary parenchyma or via hematogenous seeding from an intravascular source

Clinically, it is characterized by new or progressive pulmonary infiltrates on chest imaging accompanied by fever, purulent sputum production, leukocytosis, and worsening respiratory failure, often carrying high morbidity due to necrotizing tissue destruction and lung cavitation
