Intestinal flora consists of the bacteria and other microorganisms that live within the human digestive system. There are 10 times more bacteria in the digestive system than there are cells in the entire body. We each have about 100 trillion bacteria in our intestines,contributing to 1-1.5kg of our body weight. There are more than 400 species of bacteria found in the digestive system. These include both beneficial and harmful species, which continually compete to maintain a well-balanced intestinal flora. |
