The microbiome is a term used to describe the specific collection of microorganisms (such as fungi, bacteria and viruses) that exist in a particular environment. The word is often used to describe the community of microorganisms that live in or on the human body (e.g., in the stomach or on the skin). One human has about 40 trillion bacteria and other microbes in their system.

Many of these microbiomes support and maintain our health. But inflammation,  diet and other factors can disturb the microbiome. These changes are linked to various ailments such as cancers and autoimmune and cardiovascular diseases.

Narration



Microbiome. Microbes are the small organisms that we can just barely see under a microscope, like bacteria, fungi, viruses... And these microbes live everywhere. They live in the soil, they live in the water, and they live in and on our body. The microbiome is a new term that refers to all of the genetic material found in an individual microbe such as one of these bacteria or fungi or viruses. So if we think about the entire DNA sequence of a microbe, that is the microbiome.
