© CSA-Images/istockphoto.comIn recent years, the bacterial communities living in and on our bodies have captivated scientists and the public alike. The gut microbiome has been tied to diverse functions and linked to both health and disease. But researchers now know that the gastrointestinal tract is just one of the many microbial homes on the human body. Even sites once considered sterile—such as the eye and the reproductive organs—are revealing themselves to be hotbeds of diversity. Here, The Scientist looks at some of these bacterial communities outside the gut, including the vagina, the penis, the breast, the lung, and more.
