A home for the microbiome: Biologists identify how beneficial bacteria reside and thrive in gastrointestinal tract

The human body is full of tiny microorganisms -- hundreds to thousands of species of bacteria collectively called the microbiome, which are believed to contribute to a healthy existence. The gastrointestinal tract is home to the largest concentration and highest diversity of bacterial species. But how do these organisms persist and thrive in a system that is constantly in flux? Biologists believe they have found the answer.
