Gut Microbiome

The bacterial cells harbored within the human gastrointestinal tract outnumber the host’s cells by a factor of 10 and the genes encoded by the bacteria resident within the gastrointestinal tract outnumber their host’s genes by more than 100 times. These human digestive-tract associated microbes are referred to as the gut microbiome. The human gut microbiome and its role in both health and disease has been the subject of extensive research, establishing its involvement in human metabolism, nutrition, physiology, and immune function.
