Seres Therapeutics, Inc.

Seres Therapeutics develops experimental medicines made from living microorganisms (bacteria) to treat serious diseases. The company is testing treatments that aim to restore healthy bacteria in the digestive system and prevent dangerous infections in patients undergoing stem cell transplants or those with severe liver disease. These medicines work by changing the balance of bacteria in the gut to improve the body's natural barrier and immune response. The company is still in the research and testing stage and has not yet brought any products to market.
