Infant gut microbiomes oscillate with a circadian rhythm, even when they are cultivated outside of the body. Researchers report April 2 in the journal Cell Host & Microbe that the rhythm is detectable as early as 2 weeks after birth but becomes more pronounced with age. The finding comes from a randomized controlled trial that also showed that diet has less impact on the development and composition of the infant microbiome than previously thought.
“We found that even at very early ages of colonization, the microbial ecosystem develops this circadian rhythmicity,” says senior author and microbiome expert Dirk Haller of the Technical University of Munich. “We have shown these rhythms before in adults, but we were not sure when these mechanisms first appear.”
