Microbiota, complex communities of microorganisms, consist mainly of bacteria, archaea, fungi and viruses. They live in symbiosis, a relationship of mutual benefit to achieve a state of balance. These living entities are omnipresent: in the soil, the water, the foods we consume, and even on and in our bodies.
The microbiota, bringing together bacteria, viruses and parasites, takes place in specific environments such as the intestine, also called intestinal flora. Currently considered by the scientific community as an organ in its own right, the intestinal microbiota opens the way to innovative medicine for tomorrow

Bacteria, yeasts, viruses… Our microbiota is made up of 100,000 billion microorganisms.

The composition of the intestinal microbiota is mainly established before the age of 3 and remains relatively stable in adults. However microbial colonization of the digestive tract begins at birth, and an alteration of the microbiota in the very first months of life could predispose to certain diseases that appear later, such as obesity or certain allergies.

It is estimated that, in humans, there are around 800 species of intestinal bacteria with more than 7000 strains, which corresponds to an average microbiota mass of 2 kg.

Our intestinal microbes are for the most part our allies: without them, we would be incapable of assimilating many foods, converting them into nutrients and energy, or synthesizing certain vitamins. Our microbiota also participates in our immune system.

The composition of the microbiota, the community of microorganisms living in the digestive tract, can be modified by several factors. Here are some of the main contributors to the modulation of the gut microbiota:

Food - Antibiotics - Lifestyle - Gastrointestinal infections - Fecal transplantation - Probiotics - Hygiene practices

Intestinal dysbiosis refers to an imbalance of the intestinal microbiota, composed of microorganisms in the gastrointestinal tract. This imbalance can result from factors such as diet, antibiotics and stress, affecting the composition and activity of microorganisms. Symptoms include gastrointestinal upset, skin problems, immune disorders and mood changes. Dysbiosis can impair crucial functions like digestion, immune regulation, and vitamin synthesis.

Fecal bacteriotherapy, also called fecal transplantation or fecal microbiota transfer, is a medical procedure that involves the transfer of fecal matter from a healthy donor to a recipient with gastrointestinal disorders or other health problems associated with a disruption of the intestinal microbiota.

Many researchers, including those at Pasteur, have recently highlighted an interaction between our microbiota and: Alzheimer's - Parkinson's - Diabetes - Irritable bowel - Cancers - Depression - Endometriosis - Concentration.

Having your microbiota tested has several advantages. First of all, it allows us to understand the specific composition of one's intestinal bacteria, thus providing information on the diversity and balance of one's microbiota. This knowledge can be useful in assessing and improving your digestive health, strengthening your immune system, and even adjusting your diet to promote a healthier microbiota.

Additionally, it may be particularly beneficial for people with recurring digestive issues, individuals with a history of prolonged antibiotic use, or those looking to optimize their overall well-being.

By better understanding your microbiota, it becomes possible to adopt personalized strategies to promote optimal balance and better overall health.
