Abstract

Mammalian gastrointestinal (GI) development is guided by genetic determinants established during the evolution of mammals and matched to the natural diet and environment. Coevolution of the host GI tract (GIT) and the resident bacteria has resulted in commensal relationships that are species and even individual specific. The interactions between the host and the GI bacteria are 2-way and of particular importance during the neonatal period, when the GIT needs to adapt rapidly to the external environment, begin processing of oral foods, and acquire the ability to differentiate between and react appropriately to colonizing commensal and potentially pathogenic bacteria. During this crucial period of life, the patterns of gene expression that determine GI structural and functional development are modulated by the bacteria colonizing the previously sterile GIT of fetuses. The types and amounts of dietary inputs after birth influence GI development, species composition, and metabolic characteristics of the resident bacteria, and the interactions that occur between the bacteria and the host. This review provides overviews of the age-related changes in GIT functions, the resident bacteria, and diet, and describes how interactions among these 3 factors influence the health and nutrition of neonates and can have lifelong consequences. Necrotizing enterocolitis is a common GI inflammatory disorder in preterm infants and is provided as an example of interactions that go awry. Other enteric diseases are common in all newborn mammals, and an understanding of the above interactions will enhance efforts to support neonatal health for infants and for farm and companion animals.
