Bugs’ as drugs: Harnessing novel gut bacteria for human health. Science Daily

Scientists have grown and catalogued more than 130 bacteria from the human intestine. Imbalances in our gut microbiome can contribute to complex conditions and diseases such as obesity, inflammatory bowel disease, irritable bowel syndrome and allergies. This research will enable scientists to understand how our bacterial ‘microbiome’ helps keep us healthy and start to create tailor-made treatments with specific beneficial bacteria.  Read more…
