  • Gut Bacteria's Collection of Genomes is Unique, Remains Stable Over Time
    We all have E. coli bacteria in our gut but each of us carries a version that is genetically slightly different. The same can be said of most gut microbes: our own gut metagenome, that is the sum of all the genomes of all our gut microbes, appears to be really specific to ...More
