Preemies’ gut bacteria may depend more on gestational age than environment

The population of bacteria in premature infants’ guts may depend more on the babies’ biological makeup and gestational age at birth than on environmental factors, researchers at Washington University School of Medicine in St. Louis have found. They discovered that bacterial communities assemble in a choreographed progression, with the pace of that assembly slowest in infants born most prematurely.
