A microbiota is a community of micro-organisms (bacteria, yeasts, fungi, viruses) living in a specific environment. There is therefore a soil microbiota and an ocean microbiota, but also a number of microbiota associated with the human body: skin microbiota, vaginal microbiota, etc. and the one that has been studied most closely, the intestinal microbiota.
Every individual has an intestinal microbiota that is specific to them, comprised of about 160 different bacterial species.
The various microbiota play important roles for our health
