Gut Microbiota and the Brain

"Altering microbial composition. Exogenously administered potential probiotic bacteria or infectious agents can affect the composition of the gut microbiota in multiple ways. For example, they can compete for dietary ingredients as growth substrates, bioconvert sugars into fermentation products with inhibitory properties, produce growth substrates (for example, exocellular polysaccharide or vitamins) for other bacteria, produce bacteriocins, compete for binding sites on the enteric wall, improve gut barrier function, reduce inflammation (thereby altering intestinal properties for colonization and persistence), and stimulate innate immune responses."
