But just as we cracked the human genome and have begun to sleuth out the genetic basis of many diseases, we intend to crack the microbiome — the collection of bacteria and other organisms that colonize the human body — and understand how killing some of you and increasing the numbers of others can keep us healthier. Let’s hope you fall into that second group, for your sake.
