The human body is inhabited by trillions of microorganisms—collectively called the ‘microbiota’ or ‘microbiome’. We now know that the variety of bacteria inhabiting one’s skin, mouth and intestine can greatly influence their health. Current research efforts are intensely focused on how the microbiota assembles and functions.
