Evolution of Gut Microbiota Composition from Birth to 24 Weeks in the INFANTMET Cohort

The aim of this study was to characterise the gut microbiota development in a cohort of breast-fed infants from 1 to 24 weeks of age, using both culture-independent 16S rRNA amplicon sequencing and, in parallel, bacteriological culture. Mode of delivery (Spontaneous Vaginally Delivered (SVD), or Caesarean Section (CS)), and gestational age (pre-term (PT) or full-term (FT)), have significant effects on early neonatal microbiota composition. The data show the longitudinal effect of PT birth after the infant leaves the hospital environment.
