Answers
The intestinal microflora is a complex ecosystem containing over 400 bacterial species. Anaerobes outnumber facultative anaerobes. 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 .
Metabolic Activities
Intestinal bacteria are a crucial component of the enterohepatic circulation in which metabolites that are conjugated in the liver and excreted in the bile are deconjugated in the intestine by bacterial enzymes, then absorbed across the mucosa and returned to the liver in the portal circulation. Many drugs and endogenous compounds undergo enterohepatic circulation. Antibiotics that suppress the flora can alter the fecal excretion and hence the blood levels of these compounds. The flora also plays a role in fiber digestion and synthesizes certain vitamins.
