MAIN EDUCATIONAL POINTS from M144-4

  1. S. maltophilia is a nosocomial pathogen, and is associated with disease in immunocompromised as well as immunocompetent hosts. It is a well-reported etiologic agent of ventilator-associated pneumonia (VAP), and is likely the pathogen responsible for this patient’s disease. It is important to have a means to isolate, identify, and report this organism in significant clinical contexts.
