| Outline of Final Research Achievements |
Gut microbe colonisation begins immediately after birth,and bacterial ecosystems develop within the first few days. Previous studies have reported that the compositions of infant gut bicrobiota differ from those of adult, that substation occurs between individuals, and that bifidobacterial predominate in most infant. Furthermore, it has been demonstrated that gut microbiota developed during infancy can have long-lasting effects on the individual’s future health. However, little is known about their regularity, factors that drive the assembly of infant microbiota, and how these factors affect metabolite profiles.
We investigated gut microbiota composition and metabolic profiles using 270 stool samples obtain from 17 preterm infants and 43 healthy infants.We revealed that enterobacterial acquisition process of newborn baby treated in a neonatal intensive care unit (NICU) was different from the normal newborn baby, and the acquisition of the Bifidobacterium was remarkably delay.
