Commensal bacteria and immunity of the gastrointestinal, respiratory and genitourinary tracts
Journal Title: Advances in Hygiene and Experimental Medicine - Year 2016, Vol 70, Issue
Abstract
Commensal bacteria are microorganisms that occur among others in the gastrointestinal, respiratory and urogenital tract not exhibit the characteristics of pathogenicity, and act on the immune system and the metabolism of macroorganism and “create” protective barrier against pathogenic bacteria. Currently, it is estimated that the number of commensal bacteria inhabiting in and on human, are more than ten times the number of cells that build the body. The composition of these microorganisms depends on health and physiological status of macroorganism, including its immune status, but also largely on environmental factors (living and diet). These bacteria affecting the immune system in the gastrointestinal, respiratory and urogenital tract, stimulate the synthesis of a number of immunological substances that interact multiphase, for example: blocking the adhesion of pathogenic microorganisms and to reduce or entirely eliminate their influence on the contact and macroorganism.
