Establishment, Expansion and Modulation of Gut Microbiome: Birth to First 100 Days to Early Childhood and Later
Author(s): Vinod Nikhra*
Establishment of infant microbiome-first 100 days: The intestinal bacterial colonization begins when the fetus lies in the
lower uterus and following birth the gut microbiota is transiently dominated by Enterobacteriaceae and Staphylococcus.
The infant microbiota undergoes first transition during lactation, resulting in dominance of the gut microbiota by
Bifidobacterium and some lactic acid bacteria. The second transition occurs during the weaning period with introduction
of solid foods, leading to establishment of an adult-type of complex microbiota dominated by Bacteroidetes and Firmicutes.
The dynamic gut microbial ecology is gradually altered and stabilized during early childhood.
Expansion of gut microbiome-the early childhood: The third transition occurs during the early childhood as various
alterations influenced by di.. View More»
