Jeroen Raes, professor and group leader at VIB, Brusssels (and MetaCardis investigator) spoke at TEDx Brussels in November 2012. The topic was "Gut flora: You are your 100 trillion friends". He takes us on a guided tour of our body's microbial neighbourhood and reveals that only one in ten of the cells that make up the human body are in fact human. The rest? Microorganisms that live on and inside us. He introduces the idea of 'enterotypes' (groupings of bacteria) and reveals that there are just three distinct types that all humans appear to fit into. Such a finding, he says, could be important as many diseases are linked to disturbances in gut flora. Moving on he describes how babies, which are born sterile, become inoculated at birth and that this can have important consequences for health later on. He also describes the effects of antibiotics on gut flora and describes some surprising outcomes when even low doses are used. Finally, he talks about a toe-curling but highly effective treatment for mending broken microbiotas - faecal transplants.
