What Does Influence the Neonatal Microbiome?

This editorial aims to provide a concise summary of the factors involved in the dynamics of microbiome establishment and maturation. At the same time, it briefly updates the current knowledge and opens new questions in this regard. Many factors act as drivers of the microbiota’s development at both pre- and post-natal levels (e.g., maternal factors, antibiotic usage, type of delivery, dietary pattern, post-natal feeding type, etc.). However, it is interesting to research into its real impact, the relationship between these external modulators, and how to modulate them. The are great opportunities for new research in the field.
