common bacterial diseases of the upper digestive tract

Composition and distribution of the intestinal flora common bacterial diseases of the upper digestive tract The intestinal flora is a complex ecosystem containing more than 400 species of bacteria.

Anaerobic exceed facultative anaerobic bacteria. The flora is low in the stomach and upper small intestine, but plentiful in the lower intestine. Bacteria occur in both the lumen and on the intestinal mucosa, but not to penetrate the intestinal wall, as a rule.

Metabolic activities

Intestinal bacteria are a crucial part of the enterohepatic circulation, is conjugated in the metabolites in the liver and excreted in the bile, deconjugated in the intestine by bacterial enzymes, absorbed through the mucosa and the liver in the portal circulation. Many drugs and endogenous compounds enterohepatic circulation to undergo. Antibiotics, which can alter the flora suppress fecal excretion and thus the blood levels of these compounds. Flora plays a role in digestion of fiber and certain vitamins synthesized.
The digestive tract is a torque tube 30 feet long. It begins at the mouth and ends at the anus. In the middle, of the esophagus, stomach and intestine (bowel). Digestion of the liver and the pancreas aids in the production of bile and pancreatic juices into the intestine. The gallbladder stores bile until the body needs it for digestion.

The digestive system breaks down food and liquid in much smaller nutrients. In this complex process, the blood nutrients transported through the body to nourish cells and to provide energy. Upper gastrointestinal and lower gastrointestinal tract: The gastrointestinal tract is divided into two parts.
On the gastrointestinal infection is caused by the growth of a pathogen in the intestine.

Incubation period, the growth of bacterial cells and products cause symptoms, from 12 hours to two weeks. Symptoms of infection include fever general.

A bacterial poisoning by ingestion results of bacterial toxins formed.
