The digestive tract represents an interface between the external environment and the body where the interaction of a complex polymicrobial ecology has an important influence on health and disease. The physiological mechanisms that are altered during hospitalization and in the intensive care unit (ICU) contribute to the pathobiota's growth. Intestinal dysbiosis occurs within hours of being admitted to ICU. This may be due to different factors, such as alterations of normal intestinal transit, administration of various medications, or alterations in the intestinal wall, which causes a cascade of events that will lead to the increase of nitrates and decrease of oxygen concentration, and the liberation of free radicals.

Abstract
The digestive tract represents an interface between the external environment and the body where the interaction of a complex polymicrobial ecology has an important influence on health and disease. The physiological mechanisms that are altered during hospitalization and in the intensive care unit (ICU) contribute to the pathobiota's growth. Intestinal dysbiosis occurs within hours of being admitted to ICU. This may be due to different factors, such as alterations of normal intestinal transit, administration of various medications, or alterations in the intestinal wall, which causes a cascade of events that will lead to the increase of nitrates and decrease of oxygen concentration, and the liberation of free radicals.
