Le French Gut: Characterization of Gut Microbiota Profiles in France

At the 14th International Conference on Genomics (ICG-14), scientists from China, Sweden, Denmark, France and Latvia launched The Million Microbiome of Humans Project (MMHP) and agreed to collaborate on a large-scale microbial metagenomic project. The overarching goal is to build the world's largest database of human microbiota with one million microbial samples from the intestines, mouth, skin and reproductive system. Therefore, making it possible to characterize the microbiota of people according to age, gender, height, weight, etc. As a founding member of the MMHP, INRAE will bring the French national contribution: 100 000 faecal samples and associated nutritional and clinical data from France, by 2027, through Le French Gut project. Initiated by the MGP research unit, Le French Gut is led by INRAE and the AP-HP (Public Assistance-Hospitals of Paris), with the support and collaboration of a consortium of members from medical, scientific and industrial sectors. In order to be a participant of the project, volunteers will need to fill out an online questionnaire with 60 questions about their lifestyle, their dietary habits and their medical background. The second requirement is the stool sampling, at home. Main scientific targets of this project are the following: * Build a map of the intestinal microbiota in France, reflecting differences in term of gut microbiome through ages, gender, regions of life, diets, habits and medical status; * Describe and better understand the heterogeneity between gut microbiota of healthy subjects and investigate the connection between this heterogeneity with diet and habits. * Describe the variations of the intestinal microbiota associated with the presence and development of certain diseases (chronic diseases, neurodevelopmental disorders, neurodegenerative diseases,…)
