<P> The gut flora has the largest numbers of bacteria and the greatest number of species compared to other areas of the body . In humans the gut flora is established at one to two years after birth , and by that time the intestinal epithelium and the intestinal mucosal barrier that it secretes have co-developed in a way that is tolerant to , and even supportive of , the gut flora and that also provides a barrier to pathogenic organisms . </P>
