Microbiota: Set of microorganisms in a specific location or sample that inhabit all the surfaces of our organism.


  • Maintenance of barrier function
  • Balance of species of microorganisms
  • Local innate and adaptive immunity

A human cell is composed of three erythrocytes, 13 apidocytes, 20 muscle cells and 10 “other” cells

Distribution of bacteria in the body: 29% in the gastrointestinal tract, 26% in the mouth, 21% in the skin, 14% in the respiratory tract, 9% in the urogenital tract, 1% in the blood and 0% in the eye.

Eubiosis (a state of health in which the microbiota is normal and balanced and meets all the requirements for you to benefit from the health functions of a healthy individual) is influenced by geographic location, lifestyle, nutrition, hygiene, probiotics, antibiotics, infections, age, mode of birth and the host’s genetic heritage.

Quantitative changes: bacterial overgrowth (only in some locations).

Qualitative and metagenomic changes: symbionts (health-promoting), invasive and inflammation-inducing bacteria, genotoxic bacteria, cancer-promoting metabolites (such as DCA).
