Serratia pneumonia

Serratia pneumonia is a lower respiratory tract infection caused by Gram-negative bacilli of the genus *Serratia*, most frequently *Serratia marcescens* Pathophysiologically, the infection is characterized by acute necrotizing bronchopneumonia, alveolar exudation, and pulmonary hemorrhage, frequently resulting in microabscess formation, lung cavitation, and empyema Affected patients typically present with acute fever, hypoxemia, purulent or blood-tinged sputum, and patchy bronchopneumonic infilt...
