Interactions between many species of bacteria create a healthy environment in the human stomach and intestines. But when medicines like antibiotics upset the normal microbial balance, certain harmful species can multiply and thrive, causing infections that are difficult to cure. Scientists are successfully treating a type of digestive disorder using transplanted microbes from donors with healthy digestive systems to reestablish microbial diversity.
