To Survive in the Human Gut, Bacteria Need Genetic “Passcode”

  • Studying the gut microbiome, scientists found that bacteria which protect us from toxins do so by inheriting immunity genes against those toxins.
  • In lab dishes and in living mice, transferring genes from a specific bacteria instantly immunised against that bacteria’s toxin.
  • Which means that all our microbiomes are different, and treatments targeting the microbiome need to be highly personalized.
  • Understanding how to do it will lead to better probiotic and live biotherapeutic treatments, which hold great promise as a way to battle sickness.
