Stool sampling: Participants will have to collect a stool sample and submit it within one hour of its emission
Study summary
The goal of this study is to optimise the pre-analytical process for metagenomic analysis of the microbiota in comparison with the current reference technique.
A comparative evaluation will be performed between the following and the reference standard (quickly frozen fresh stool):
i) faecal sample collection devices commonly used in France and abroad for metagenomics, metabolomics and culturomics; ii) self-collection device that would allows the collection of faecal material and the generation of aliquots for all possible omic assessments for research purposes, including metagenomic analysis, as well as culturomics and faecal transfer to animal models.
