Human microbiota includes all microorganisms, saprophytes and pathogens that colonize our bodies. Recent advances in metagenomic analysis techniques have expanded our knowledge of the microbiota and fundamentally changed our view of its relationships with the immune system. The commensal flora appears to be essential to the development of the immune system, and the diversity of the microbiota is correlated with good health status of individuals. These findings open up new conceptual and therapeutic approaches in chronic inflammatory diseases.
