[Summary of the 8

The microbiota represents all the microorganisms including viruses, bacteria, fungi, and parasites, that have a symbiotic relationship with their host and that are present in a particular system (or niche) of the human body such as the skin, the respiratory tract, the urogenital tract or the digestive tract. This paper is a narrative review of all talks given at the 8th edition of the « Feeding the Microbiota » symposium organized at the Geneva University Hospitals. The symposium gathered 346 participants, both onsite and online, from 23 countries all-around the world. The main thematic of this edition focused on the composition of the gut microbiota as affected by prebiotics and postbiotics and their effects on various diseases.
