Abstract:

Fermented milk with B. bifidum associated with Lb. acidophilus allows a greater decrease of E. coli that when milk is fermented with B.bifidum alone or enriched with casein hydrolyzate (bifidig?ne factor). Indeed, changes in the number of E. coli in the feces of mice were given two treatments: preventive treatment (before contamination with E. coli) and a therapeutic treatment (after contamination with E. coli, showed better results when it comes to treatment preventive and an antagonistic effect significantly higher in the presence of two species together with a rate of decrease in E. coli 90%, and the third day of treatment. However, a reduction ratio of 23%, only, was obtained with the hydrolyzate of casein, and no decrease was observed when B. bifidum alone. In therapeutic treatment, a percentage decrease of 94.9% was noted after taking the milk fermented with B. bifidum in mixed culture. A mortality rate of 50% was noted for having received the batch E.. coli. Results of Audit of the intestinal flora after dissection mice show the ability of both species to survive many during their gastric transit in order to exert an antagonistic effect towards the implementation of enteropathogenic E. coli, responsible for childhood diarrhea. This study confirms the role of milk fermented with B. bifidum associated with Lb acidophilus in the fight antidiarrheal.
