*Escherichia coli* pneumonia is an acute lower respiratory tract infection characterized by bacterial inflammation and consolidation of the pulmonary parenchyma caused by the Gram-negative bacillus *Escherichia coli* Pathophysiologically, the organism infects the lungs via microaspiration of colonized oropharyngeal secretions or through hematogenous seeding secondary to a concurrent bacteremia Clinically, affected patients present with fever, cough, purulent sputum, dyspnea, and pulmonary infilt...

While it can present as a community-acquired infection, it most commonly develops as a hospital-acquired or ventilator-associated pneumonia in older adults, hospitalized patients, or immunocompromised individuals with underlying comorbidities such as diabetes mellitus, chronic lung disease, or recent abdominal or urinary tract pathologies Clinically, affected patients present with fever, cough, purulent sputum, dyspnea, and pulmonary infiltrates on chest imaging, often carrying a high risk of ba...
