Did you know we all have at least 5 microbiomes?

The human body is home to different communities of microorganisms, also called the human microbiota, which includes bacteria, archaea and fungi. Together they can weigh up to 1.5 kg. They can be found on the skin, in the digestive tract, the vagina, urinary tract and the oral cavity.

These microbiota, the environment where they are active and the whole spectrum of molecules produced by the microorganisms are called the microbiome.  The environment defines the microbiome, hence we have a skin microbiome, gut microbiome (digestive tract), oral microbiome, vaginal microbiome and urinal microbiome. The microbiome with the highest density of microorganisms is the gut microbiome, estimated to house 90-95% of all microbiota.
