The region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.
<h3>The normal flora of the alimentary tract</h3>
Normal flora are those microorganisms that resides in a living organism without causing it harm or diseases.
These normal flora become established in different parts of the body from birth such that the normal flora found in the mouth is not the same as the one found in the colon of the alimentary tract.
From research works, the large intestine (colon) is known to contain 100 billion per milliliter of fluid culture.
The massive numbers of bacteria in the large intestine (colon) creates a great special variation in the flora. The streptococci and lactobacilli found in the colon often adhere to cells by means of capsules surrounding the bacteria.
Therefore, the region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.
