ABSTRACT

The pathogenic role of certain microorganisms of intestinal flora has been demonstrated in experimental colitis in animals and strongly suspected in inflammatory bowel disease in human, especially in Crohn's disease and pouchitis. Probiotics are living non pathogenic microorganisms that, upon oral ingestion exert benefits on human health by modulating enteric flora or by stimulation of local immune system.
