Mutualistic presence of normal Flora in Human Intestine: A review

Abstract

Human body contains a huge number of micro-organisms in its intestine. It is ten times more in number compared to the number of human body cells. These micro-organisms are mainly anaerobic bacteria and perform useful functions in relation to development of gut, and production of vitamins and hormones. These bacteria also perform a wide range of metabolic functions. The present article reviews briefly the mutualistic relationship of intestinal flora with human intestine along with their pathogenic behaviour to some extent.
