Dr. Lita Proctor, program director for the Human Microbiome Project, and Dr. Martin Blaser, Professor of Internal Medicine and of Professor of Microbiology at NYU School of Medicine, talk about the 100 trillion good bacteria that live in the human body and the five-year federal project to sequence the genetic material of the bacteria taken from 250 healthy individuals. They’ll explain what they found, how healthy bacteria works in the body, and why it’s important for good health.
