Abstract

Physiologically, internal organs such as lower airways and bladder, are sterile. However, colonization of lower airways and bladder by potentially pathogenic microorganisms (PPMs) is common in critically ill patients. Colonization of the internal organs generally follows impaired carriage defense of the digestive tract, which promotes PPM carriage and overgrowth, and impaired defenses of the host against colonization due to illness severity. Failure to clear colonizing microorganisms from the internal organs invariably leads to high concentrations of PPMs, predisposing to infection. The host mobilizes both humoral and cellular defense systems to hinder the invading microorganisms.
