When your beneficial gut bacteria thrive, they also act to make it difficult for pathogenic bacteria to survive. Good bacteria compete with bad bacteria for nutrients, space and attachment to cell surfaces.
Discouraging the Bad
Your good bacteria can change the pH of the local gut environment in a way that discourages the growth of pathogenic bacteria. If the numbers of those pathogens stay low, there's less chance of them causing illness. Beneficial bacteria can also secrete substances that are toxic to bad bacteria.
When your probiotics are strong and healthy, their populations flourish, leaving little room and food for the pathogens. This crowding out of the pathogens is referred to as "competitive exclusion". Increasing the good microbial population can reduce the harmful gut antigens and reduce the secretion of mediators that cause inflammation.
MOS (mannan oligosaccharide) included in ProBiotein, may have an effect on pathogenic bacteria that goes beyond just keeping beneficial bacteria healthy. MOS may influence bacterial attachment in the intestinal tract. Recent research in companion animals, has shown that this prebiotic fiber can attach to salmonella. MOS may also affect intestinal morphology, the innate immune system and the adaptive immune system in a beneficial way.
By competitively excluding the bad, pathogenic bacteria in your digestive system, you can reduce the chance of illness, improve the ability of your GI tract to efficiently take up important nutrients and allow your immune system the chance to respond effectively. Helping the good bacteria and discouraging the bad bacteria, are important to your overall health.
