Commensal microbiota maintain a symbiotic relationship with humans.
The benefits that a healthy commensal microbiota brings to our organism are:
- Barrier functionbarrier function: it is responsible for maintaining the integrity of the intestinal epithelium by preventing the growth of pathogenic microorganisms or by promoting the integrity of intercellular junctions.
- Sulforeducing bacteria: produce hydrogen sulfide (a gas with a rotten egg odor). This gas, at high levels, is toxic to the intestinal mucosa, producing diarrhea and constipation in the large intestine. It can also lead to gastrointestinal diseases such as Irritable Bowel Syndrome (IBS) or inflammatory bowel disease.
- Immunomodulatory Function: Modulates the correct functioning of the immune system at intestinal and systemic level, inducing inflammatory effects.
- Proteolytic: colonize the large intestine and are responsible for protein digestion. When there is overgrowth, they release a large amount of metabolic intermediates (ammonia, phenols or indores) which, on certain occasions, can enter our organism causing bacterial endotoxemia.
In many occasions (stress, antibiotics or diseases) the microbiota can be destabilized which affects its functionality. That is why it is very important to take care of our intestine with a varied diet and a healthy and balanced life.
