Anaerobic pneumonia

Anaerobic pneumonia is a lower respiratory tract infection caused predominantly by anaerobic or mixed aerobic-anaerobic bacteria originating from the oral cavity, such as species of *Peptostreptococcus*, *Fusobacterium*, *Prevotella*, and *Bacteroides* It typically arises following micro- or macro-aspiration of oropharyngeal or gastric secretions, disproportionately affecting individuals with impaired consciousness, dysphagia, neuromuscular disorders, or severe periodontal disease Clinically, it...

Pathophysiologically, the aspirated inoculum triggers tissue necrosis and parenchymal inflammation, frequently localized to gravity-dependent pulmonary segments

Clinically, it often presents with an indolent or subacute onset characterized by low-grade fever, cough productive of foul-smelling or purulent sputum, weight loss, and an elevated risk of progressing to necrotizing pneumonia, lung abscess, or empyema
