Probiotics increase gut bacteria diversity in extremely preterm infants

Scienmag

A new clinical study has shown that supplements of a lactic acid bacterium may have positive effects by increasing the diversity of intestinal bacteria in these infants. Extremely preterm infants can suffer from a life-threatening inflammation of the gut.
