Invasive burn wound sepsis with Pseudomonas aeruginosa is a major concern in burn patient care settings. It is difficult to treat and may cause high mortality among patients with extensive burn wounds. Therefore, one primary goal of burn care is to prevent colonization and infection of P. aeruginosa. Patient colonization refers to the isolation of the targeted pathogen (organism) from the patient (e.g., sputum, wound surface, urine, and stool).
