Vaginal seeding after cesarean birth: Can we build a better infant microbiome?

Abstract

In this issue of Med, Song et al. compared 174 maternal and 177 infant microbiota after vaginal and cesarean delivery, including 30 vaginally seeded cesarean-born infants. Vaginal seeding partially corrected the microbial divergence observed between cesarean- and vaginal-born infant microbiomes. Infant microbiota resembled corresponding maternal sites, despite delivery mode or seeding.
