The makeup of our microbiomes -- the unique communities of bacteria, viruses and other microbes that live in and on us -- have been linked, with varying degrees of evidence, to everything from inflammatory bowel disease to athletic performance.
But exactly how could such tiny organisms have such immense influences on a person?
University of California San Diego researchers have created the first-ever map of all the molecules in every organ of a mouse and the ways in which they are modified by microbes. In one surprising example, they discovered that microbes control the structure of bile acids in both mice and people.
The study, published February 26, 2020 in Nature, was led by Pieter Dorrestein, PhD, professor and director of the Collaborative Mass Spectrometry Innovation Center in the Skaggs School of Pharmacy and Pharmaceutical Sciences at UC San Diego, and Robert Quinn, PhD, assistant professor at Michigan State University.

How resident microbes restructure body chemistry
A comparison of normal and germ-free mice revealed that as much as 70 percent of a mouse's gut chemistry is determined by its gut microbiome. Even in distant organs, such as the uterus or the brain, approximately 20 percent of molecules were different in the mice with gut microbes.
