ONLINE COVER Baby Steps for the Microbiome. Although the gut microbiome has been well studied in adults, less is known about its development in infants and young children. Two studies of more than 80 infants followed for the first 2 to 3 years of life now reveal the effects of birth mode, diet and antibiotic treatment on gut microbiome development (Yassour et al., Bokulich et al.) The investigators show that antibiotics, cesarean delivery and formula feeding can alter development of the infant microbiome, reduce bacterial diversity and transiently increase the presence of antibiotic resistance genes [CREDIT: LIOR FRIEDMAN/LESLIE GAFFNEY/BROAD INSTITUTE]
