The intestinal community, including the commensal microbial flora as well as the host tissues, represents a functional whole in vivo. Under physiological circumstances, this symbiosis brings great benefit for the host; however, critical illness induces profound disturbances in the intestinal ecosystem affecting both procaryotic and eucaryotic members. Today, 25 years after the gut was first described as a motor of multiple organ dysfunction syndrome, the role of the injured splanchnic compartment in the pathomechanism and development of critical illness is still in the first line of research. Multiple mechanisms have been identified by which the stressed gut may affect host homeostasis, and how external intervention might help to rebalance physiology. This paper provides a brief overview of the present of this field.
