Proteus pneumonia

Proteus pneumonia is a bacterial lower respiratory tract infection of the lung parenchyma caused by members of the Gram-negative genus *Proteus*, most commonly *Proteus mirabilis* It predominantly affects hospitalized, debilitated, or immunocompromised patients, particularly older adults, individuals with chronic pulmonary or neurological diseases, and those prone to microaspiration or requiring mechanical ventilation

Proteus pneumonia is a bacterial lower respiratory tract infection of the lung parenchyma caused by members of the Gram-negative genus *Proteus*, most commonly *Proteus mirabilis* The infection typically manifests with fever, productive cough, dyspnea, hypoxemia, and pulmonary consolidation on chest radiography, with severe presentations potentially complicated by necrotizing tissue damage, abscess formation, or systemic bacteremia

It predominantly affects hospitalized, debilitated, or immunocompromised patients, particularly older adults, individuals with chronic pulmonary or neurological diseases, and those prone to microaspiration or requiring mechanical ventilation Pathophysiologically, the organism colonizes the respiratory tract via aspiration of oropharyngeal secretions or hematogenous seeding from an extrapulmonary site, such as an infected urinary tract
