Scientists Chip Away at the Mystery of What Lives in Our Mouths

Sequencing of harmless oral bacterium offers insights about its disease-causing relative

COLUMBUS, Ohio – Scientists have pieced together sections of DNA from 12 individual cells to sequence the genome of a bacterium known to live in healthy human mouths.

With this new data about a part of the body considered “biological dark matter,” the researchers were able to reinforce a theory that genes in a closely related bacterium could be culprits in its ability to cause severe gum disease. (more…)
