Implantation du microbiote intestinal chez l'enfant : ontogenèse d'une niche écologique

Intestinal microbiota is a complex ecological community of its collective activities and interactions with humans. In this niche, the balance is provided by control feedbacks, but external factors or even some resident bacteria can destabilize and promote acute or chronic pathology. First weeks of life are critical in the establishment of the intestinal microbiota and also in the development of these interactions. Prematurity promotes initial dysbiosis and dynamic of establishment of intestinal microbiota different of term neonates. Dysbiosis of the intestinal microbiota of preterm infants can lead to early infectious diseases. Its impact on the rest of life remains to be determined.
