What causes Stenotrophomonas maltophilia?

S. maltophilia is a water organism which survives and multiplies in hospital environments such as respiratory secretions, urine, intravenous (IV) fluids, and irrigant solutions. Contamination may spread in a variety of ways. Sources of colonization may include personnel, hands, antiseptic soaps, hand lotion, respiratory equipment and/or fluids, ultrasonic nebulizers, inhalation medications, respirator tubing, IV lines and/or fluids, central venous catheters, pressure monitoring devices, urine, and other sources. Infections typically only occur in individuals with severely impaired immune systems. Factors that increase an individual's risk for S. maltophilia infection include admission to an intensive care unit, prolonged hospitalization, HIV infection, cancer, cystic fibrosis, neutropenia, mechanical ventilation, recent surgery, trauma, and previous therapy with broad-spectrum antibiotics.[1][2][3]
