Abstract

Karima OY, Meddah B, Tir TA

The intestinal flora called the intestinal microbiota, consists of different bacteria and other microorganisms which occur naturally in the gastrointestinal tract organs components. These tract bacteria are present in their millions and help the functioning of the body in particular allowing aid to degradation of certain molecules into absorbable substrates. They also protect against invasion of the gut by other pathogenic bacteria, that is to say which may be responsible for disease. Factors like stress, antibiotics and diet can affect the balance of intestinal flora and in case of imbalance, digestive disorders type bloating, diarrhoea or vomiting may occur. Rattus norvegicus of weights 100 kg, from Algerian West Firm are scarified and isolation of their ileum and colon respectively. Two strains of bacteria, Escherichia coli and Lactobacillus are then purified and identified.
