Microbes- INTESTINAL BACTERIA

Microbes. They’re invisible. They’re everywhere. And they rule.
INTESTINAL BACTERIA: The human gut teems with bacteria, many of their species still unknown. They help us digest food and absorb nutrients, and they play a part in protecting our intestinal walls. Gut bacteria may also help regulate weight and ward off autoimmune diseases.

The human mouth hosts a panoply of microbes, some taking up residence on the mouth lining (blue) within days after birth. Harmful species form biofilms, like the plaque that encourages tooth decay, or colonize the crevices between teeth and gums, causing periodontal disease. Oral probiotics designed to boost the population of species that outcompete pathogenic ones could help prevent or reverse dental disease.

The bug lives harmlessly in the noses of about a third of us. But it can turn rogue, causing skin infections—or worse. Heavy use of antibiotics since the middle of the last century has prompted the evolution of deadly superbug strains.
