The Gut Microbiota For Health World Summit has become the internationally leading platform for scientific exchange in the booming area of gut microbiota research. The Summit was initiated as an annual event in 2012 by the Gut Microbiota & Health Section of the European Society of Neurogastroenterology and Motility (ESNM). “We are delighted to have all these excellent associations joining forces in order to further advance gut microbiota research,” says the section’s president Prof Fernando Azpiroz (Hospital General Vall d’Hebron, Barcelona, Spain).
