摘要:
Infections of the gastrointestinal tract are a major health problem for both adults and children worldwide. Changes in the normal human gut microflora result in the development of intestinal disorders. Pathogenic bacteria alter the intestinal microecology and intestinal colonization resistance. A healthy gastrointestinal microflora forms a barrier against invading organisms. Normal intestinal microbes and some probiotic bacteria can enhance the host’s defence mechanisms against pathogens. They can also improve intestinal immunity by adhering to intestinal mucosa and stimulating local immune responses. Thus the maintenance of a balanced intestinal microecology improves the ability to preserve intestinal integrity.
