Development and role of intestinal microbiota in term and preterm newborn babies. Accent on breast feeding

Intestinal microbiota (IM) plays in human organism a number of various functions including a participation in metabolic procecces, stimulation of immune function, competition with pathogenic flora, fermentation activity in colon. Microbial colonization of sterile gastrointestinal tract of newborn is based on several natural principles and depends on mode of delivery, vaginal and fecal flora of own mother, external factors (hospitalization, antibiotic therapy), and as well is regulated by breast feeding or bottle feeding. Besides that there is a proven difference between term and preterm newborn babies. Microbial community (so called Microbiome) of human milk with its complicated microbial society plays a key role in IM development, especially in combination with human milk oligosaccharides evolutionary connected with human intestinal microbiota development.
