Probiotics are live microorganisms added to food to remain active
in the intestine and exert important physiological effects. Ingested in
sufficient quantities, can have beneficial effects, such as contributing
to the balance of the intestinal microbiota of a host and enhance the
immune system. Probiotics for IBS
can pass through the digestive tract and feces recovered alive, but
also adhere to the intestinal mucosa. They are not pathogenic, except in
cases where immunocompromised individuals are supplied.
It does not document the benefit to any other strain, although the same species as the one tested, nor a fortiori for the entire group of probacteria. The FAO / WHO which provides this definition refers to non-pathogenic microorganisms present in food or added to them. This distinction is often not taken into consideration, is of extreme importance as regards the safety of use of viable bacteria.
The consequences of these interactions as a whole, however, are yet to understand. It is believed that probiotics can have several beneficial effects on immune function. They can protect from the pathogenic species through inhibition of growth through competition and, as suggested by some evidence, act on the immune system by increasing the number of cells that produce immunoglobulin, enhancing phagocytosis, increasing the proportion of T lymphocytes and NK cells (Natural Killer).
A probiotic contain viable micro-organisms. It is a functional food product. In sufficient quantities ingested, biotics can have a healthy effect on the host organism. The extent of this effect is possible but controversial in many cases. In comparison to "conventional" food, an increased effect of probiotic food products, not shown. The longest applied as pro-biotics organisms are lactic acid bacteria, but also yeast and other species in use.
No type of product containing pro-biotics has been approved by the Food and Drug Administration for medical indications. A 2010 study suggests that any positive effects of probiotic therapy in the prevention of secondary infections, a common complication of antibiotic therapy, may result from the fact that the ingestion of foods containing good bacteria helps to keep the immune system called, first, that the helps to counteract the negative effects of the disease and the intake of antibiotics.
There is broad consensus that some probiotics can improve the quality of life of those suffering from gastrointestinal disorders (bloating, abdominal pain, etc.). Within this population, the group of people who suffer from Irritable Bowel Syndrome (IBS) has been taken as a reference (even for assessments by EFSA) to test the potential of probiotics in improving symptoms.
Now data is available on specific effects, such as attenuation of inflammatory bowel disease, the prevention and treatment of diarrhea induced by pathogens urogenital infections, atopic diseases. They were and still are objects of study the interactions between biotics and immune system, the potential of biotics as anti-cancer.
There is no evidence that the bacteria that inhabit the intestine (the so-called intestinal microbiota) may modulate the mucosal immune system; some probiotic strains are able to establish a dialogue cross (cross-talk) with the intestinal immune system (GALT, Gut Associated Lymphoid Tissue) and to therefore have an effect on it.
