Researchers take a closer look at the genomes of microbial communities in the human mouth

Bacteria often show very strong biogeography—some bacteria are abundant in specific locations while absent from others—leading to major questions when applying microbiology to therapeutics or probiotics: how did the bacteria get into the wrong place? How do we add the right bacteria into the right place when the biogeography has gotten 'out of whack'?
