The human microbiome is the collection of microorganisms that include bacteria, protozoa, fungi, viruses and other one-celled organisms in and on the body. Human-microbe interactions play a crucial role in individual health. The microbes are both external on the skin, mouth, genitals and internal in the lungs and digestive organs. The microbiomes have many essential functions in the body – from helping digestion, to supporting the development of the immune system and preventing infections. Impressively there are also interactions between gut microbes and the brain which means we may be able to support mental health through changing the gut microbiome.
