Pseudomonas aeruginosa is one of the most important and most commonly considered pathogens in the differential diagnosis of gram-negative infections. Consideration of this organism is important because it causes severe hospital-acquired infections, especially in immunocompromised hosts, is often antibiotic resistant, complicating the choice of therapy, and is associated with a high mortality rate.

The clinical manifestations, diagnosis, and treatment of P. aeruginosa pneumonia will be reviewed here.

The general principles of antimicrobial treatment of infections caused by P. aeruginosa, including antibiotic options and decisions on combination therapy, are discussed in detail elsewhere. (See "Principles of antimicrobial therapy of Pseudomonas aeruginosa infections".)

The clinical manifestations and management of other P. aeruginosa infections and the epidemiology and pathogenesis of infection with this organism are also discussed separately.

(See "Epidemiology, microbiology, and pathogenesis of Pseudomonas aeruginosa infection".)
