The dynamics of the microbial colonization of the gut from neonates to toddlers. The relationship of microbes and the immune system in infants

Definition

The immune system of infants is “educated” by a series of microbial gut colonizers that contribute to the host’s health status.

Introduction

Mammals develop in utero with no or little exposure to bacteria but are naturally born heavily inoculated with the microbiota of the maternal birth canal. The events that follow ought to have enormous adaptive value: there is a long period of strict lactation during which the diversity of the colon microbiota is minimal, and the development of the baby’s immune, sensorial, and motor systems is remarkable. The developmental events during lactation in relation to the microbiota have been the subject of little study and are reviewed in this paper.

Life Inside Uterus

The fetal intestine is filled with swallowed amniotic fluid (Fanaro et al. 2003) and is assumed to be free of microorganisms...
