Detailed explanation-1: -Gut bacteria are important components of the microbiota ecosystem in the human gut. Commensal bacteria colonize in the gut shortly after birth and comprise approximate 1000 species, most of which are unknown species belonging to anaerobic strains [2, 3].
Detailed explanation-2: -The flora is sparse in the stomach and upper intestine, but luxuriant in the lower bowel. Bacteria occur both in the lumen and attached to the mucosa, but do not normally penetrate the bowel wall .
Detailed explanation-3: -Friendly bacteria live mostly in the large intestine and part of the small intestine. The acidic environment of the stomach does not allow bacterial growth.
Detailed explanation-4: -Most are helpful or at least harmless. The three or so pounds of bacteria living in our gut-mostly in the large intestine-help us digest all manner of food.
