Pseudomonas fluorescens Pneumonia: A Case Report and Review of the Literature

Year: 2026

Type: article

Abstract: Pseudomonas fluorescens is a rare, environmental Gram-negative bacterium that has been rarely reported as a cause of respiratory tract infections. This paper presents a case of a 72-year-old male who developed community-acquired pneumonia due to P. fluorescens. The diagnosis was made by sputum culture and he responded to meropenem treatment. A literature search revealed three previously reported cases of P. fluorescens pneumonia. These cases primarily affected elderly male patients. All reported patients demonstrated positive clinical outcomes following appropriate antimicrobial therapy. This case highlights that although P. fluorescens is often considered a colonizer, it may act as a potential pathogen in selected clinical settings.
