On behalf of the International Society of Microbiota, we are pleased to inform you that the 8th World Congress on Targeting Microbiota will be organized on October 20-22, 2021 in Paris at the UNESCO. The meeting will be a hybrid conference: in person and virtually. The final decision about the format will be next July. We keep our optimism in these particular moments. During three days, two workshops will be dedicated to Gut & Skin Microbiota and many oral and poster communications will be presented.
