Use of probiotics in praxis is based not only on local but also systemic biomedical effects. Probiotics do have inhibitory effect on pathogens, they maintain or improve digestive health, and have immunostimulating, antitumour, anticholesterol and antiallergic activity. Mechanism of probiotics activity has not been completely explained, and more scientific work is needed. Inhibitive effects of probiotics can be caused by competition for receptors on gut mucosa, competition for nutrition, production of antibacterial substances, and also by stimulation and modulation of consumer’s immunity. Using probiotics not in prevention, but also as a part of treatment is much more often in different areas of human medicine.
