The protective effect of probiotics

The intestinal microbiota constitutes a complex ecosystem of probiotics that play an important role in the treatment of acute infectious diarrhea. As a consequence there has been a rapid incorporation of bacterial strains with defined beneficial functions (probiotics). The protective effect of probiotic bacteria against gastrointestinal pathogens and their mechanisms of action has been one of the areas of greatest interest. Strains of the genus Bifidobacterium are major members of the intestinal microbiota and one of the main groups of probiotics. This genus is considered essential for the maintenance of intestinal balance.
