We are not alone: a meeting with your gut microbiome


Omry Koren (BIU) 


The gut microbiome is the collection of microorganisms including bacteria, archaea, viruses and fungi found within the gut and their genetic information. Our gut microbiota has been shown to have broad effects on our health and well-being, impacting our immune system and metabolism, detoxifying various ingested components, and even effecting behavior. Changes in gut microbiota composition are correlated with different life stages, diet and geographical location, exercise, use of antibiotics and a wide range of disease states. In the next years, this rapidly growing research field is likely to provide more precise interactions and networks connecting hosts with their microbiome.



Related Research Questions


  1. How is the microbiota assembled and maintained over a lifetime?
  2. How personal is each individual’s microbiota?
  3. How does its composition contribute to well-being or disease predisposition and pathogenesis?
