Pseudomonas aeruginosa Infections: Practice Essentials, Background, Pathophysiology
November 5, 2024 - Pseudomonas aeruginosa is an opportunistic pathogen. It rarely causes disease in healthy persons. In most cases of infection, the integrity of a physical barrier to infection (eg, skin, mucous membrane) is lost or an underlying immune deficiency (eg, neutropenia, immunosuppression) is present.

It is identified on the basis of its Gram morphology, inability to ferment lactose, a positive oxidase reaction, its fruity odor, and its ability to grow at 42° C. Fluorescence under ultraviolet light is helpful in early identification of P. aeruginosa colonies and may also help identify its presence in wounds. Pseudomonas aeruginosa is frequently resistant to many commonly used antibiotics.
