BOSTON — Humans may be in charge of which bacteria live in and on them, researchers report. Scientists used to think that what people ate and where they lived were the main determinants of the microbes that colonize human bodies, but the new studies suggest the immune system selects its microbial companions. Paradoxically, that control may make it harder to change which microbes call a person’s body home.
