ONLINE COVER Bugs in Guts. The image shows the human gut epithelia teeming with symbiotic microbes that interact with the host to maintain health. A joint Science and Science Translational Medicine special section explores basic research advances in microbial ecology, microbial and host metabolisms, and the interactions between gut microbes and the host immune system. Complementary articles discuss how this new-found knowledge can be exploited therapeutically to boost health and nutrition, to combat infectious disease, and to control noncommunicable diseases such as obesity and diabetes.
