The Human Microbiome

The human microbiome is the collection of all the microorganisms living in association with the human body. These communities consist of a variety of microorganisms including eukaryotes, archaea, bacteria and viruses.

Bacteria in the human body

Bacteria in the human body are abundant and necessary for our health. They help digest our food, regulate our immune system, protect against other bacteria that cause disease, and produce vitamins including B vitamins and vitamin K.

More bacteria than human cells

Recent research suggests that the human body is made up of more bacteria than human cells. However, the exact ratio is currently a topic of dispute among scientists.

Role of the microbiome

The human microbiome plays a vital role in our health. Disruptions to the microbiome, known as dysbiosis, have been linked to a number of health problems including inflammatory bowel disease, obesity, and cancer.

Future research

Future research on the human microbiome is likely to revolutionize our understanding of human health and disease. It may lead to new strategies for prevention and treatment of a wide variety of health conditions.
