Neutral mutants can prevail in gut microbiota, enhancing diversity

Scientists at EPFL and Sorbonne propose a new model of the diversity and evolution of gut bacteria that shows how the gut environment helps neutral mutations become prevalent, with significant potential implications on health ...

How the immune system keeps the intestinal flora in balance

The bacteria living in the intestine consist of some 500 to 1000 different species. They make up what is known as the intestinal flora, which plays a key role in digestion and prevents infections. Unlike pathogens that invade ...
