These bacteria enhance the population
of beneficial bacteria in the human gut, suppress pathogens, and
build up resistance against intestinal diseases. The clinical applications
include treatment of acute rotaviral diarrhea, lactose maldigestion,
constipation, colonic disorders, and side effects of pelvic
radiotherapy. In some cases, ingestion of these bacteria was effective
in preventing food allergy such as milk hypersensitivity
and changes associated with colonic cancer development (Salminen
and others 1998).
