Predicting Gut Microbiome Diversity from Blood

Blood metabolome predicts gut microbiome α-diversity in humans


  • Study the reflection of gut microbiome in the bloodstream
  • Find blood biomarkers for low, potentially problematic, gut microbiome diversity
  • Study the complex interconnections between host metabolism, gut microbial composition, and human health.

Summarizing paragraph:

The microbes in our gut are important to our health, but we do not yet know how to tell if a particular mix of microbes is “healthy”. We have found that gut microbiome diversity is strongly reflected in its host by a small subset of blood metabolites, which may lead to clinical tests to monitor the health of our gut’s tenants. We believe that the key to defining and monitoring a healthy state of the microbiome is examining its reflection in the blood, which may be more stable, quantifiable, and universal.
