The small intestine microbiota, nutritional modulation and relevance for health

- The genera Streptococcus and Veillonella are active small intestinal commensals.
- The streptococci of the small intestine are phylogenetically and functionally diverse.
- The small intestine microbiota is amenable to dietary modulation.
- Host-microbe interactions in the small intestine strongly affect immune, metabolic and endocrine functions.
- The small intestine microbiota plays important roles in human health and disease.
