Enterobacter pneumonia

Enterobacter pneumonia is a bacterial lower respiratory tract infection caused by opportunistic, Gram-negative bacilli of the genus *Enterobacter*, most frequently members of the *Enterobacter cloacae* complex It primarily manifests as a nosocomial infection—such as hospital-acquired pneumonia or ventilator-associated pneumonia—affecting hospitalized, critically ill, or immunocompromised individuals, as well as elderly patients with structural lung disease Pathophysiologically, the condition inv...

It primarily manifests as a nosocomial infection—such as hospital-acquired pneumonia or ventilator-associated pneumonia—affecting hospitalized, critically ill, or immunocompromised individuals, as well as elderly patients with structural lung disease

Pathophysiologically, the condition involves the microaspiration of colonizing oropharyngeal flora or contaminated respiratory equipment into the lower respiratory tract, triggering acute alveolar inflammation and tissue consolidation Clinical presentation includes fever, dyspnea, hypoxemia, purulent sputum production, and new pulmonary infiltrates on chest imaging, often complicated by inducible AmpC beta-lactamase production that drives resistance to multiple beta-lactam antimicrobials
