Impact of prematurity and perinatal antibiotics on the developing intestinal microbiota: A functional inference study
[Background] The microbial colonization of the neonatal gut provides a critical stimulus for
normal maturation and development. This process of early microbiota establishment, known to be
affected by several factors, constitutes an important determinant for later health.[Methods] We studied
the establishment of the microbiota in preterm and full-term infants and the impact of perinatal
antibiotics upon this process in premature babies. To this end, 16S rRNA gene sequence-based
microbiota assessment was performed at phylum level and functional inference analyses were
conducted. Moreover, the levels of the main intestinal microbial metabolites, the short-chain fatty
acids (SCFA) acetate, propionate and butyrate, were measured by Gas-Chromatography Flame
ionization/Mass spectrometry detection.[Results] Prematurity affects microbiota composition at
phylum level, leading to increases of Proteobacteria and reduction of other intestinal microorganisms.
Perinatal antibiotic use further affected the microbiota of the preterm infant. These changes involved
a concomitant alteration in the levels of intestinal SCFA. Moreover, functional inference analyses
allowed for identifying metabolic pathways potentially affected by prematurity and perinatal
antibiotics use.[Conclusion] A deficiency or delay in the establishment of normal microbiota function
seems to be present in preterm infants. Perinatal antibiotic use, such as intrapartum prophylaxis,
affected the early life microbiota establishment in preterm newborns, which may have consequences
for later health.This work was founded by the EU Joint Programming Initiative–A Healthy Diet for a
