For a long time, babies were thought to be born germ-free. Now we know they carry some bacteria and that the delivery mode can influence the microbiota they are starting life with and even their health.

Researcher José Clemente, assistant professor at Icahn School of Medicine at Mount Sinai in New York City, investigates whether we can revert the effects of an abnormal microbial colonisation after, for instance, a C-section. He attended the 5th Gut Microbiota for Health World Summit 2016, held in Miami and we had the opportunity to interview him and talk about the importance of gut microbiota at early life. We hope you enjoy the interview.
