Summary: Not all bacteria are bad. Within each of us are over 1,000 species of good bacteria that live in our gut, skin, mouth, and other exposed surfaces that we couldn't survive without. Dr. June Round, Assistant Professor in Pathology at the University of Utah, explains how good bacteria that live in our bodies work with our immune system to protect us from diseases in ways you might have never imagined. She also discusses new research suggesting that these microorganisms may also influence our behavior and the development of autism.
