Pseudomonas aeruginosa[‚süd·ə‚mōn·əs ‚ar·ə·jə′nō·sə]
An opportunistic pathogen that is the most significant cause of hospital-acquired infections, particularly in predisposed patients with metabolic, hematologic, and malignant diseases. It produces toxic factors such as lipase, esterase, lecithinase, elastase, and endotoxin, some of which may contribute to its pathogenesis.
