Extent of Oral–Gut Transmission of Bacterial and Fungal Microbiota in Healthy Chinese Adults

Abstract

The oral–gut microbiota axis in health is a fundamentally important and clinically relevant topic; however, our current understanding of it remains biased and incomplete. By characterizing the bacterial and fungal microbiomes in paired oral rinse and stool samples from a large cohort of healthy Chinese adults, here we provided new evidence that oral–gut microbiota transmission is limited in non-Western population and across biological domains.
