The surface of our organs is host to a microcosm of beneficial microbes (good germs !). This microcosm comprises of approximately 100,000 billion bacteria, yeasts, and fungi that go by the name of microbiota. Its our own personal, safari park, microbe-style ! These microbes live in optimal conditions, in terms of temperature, pH value, water levels, hormones, exposure to UV... And it's the combination of our microbiota and their environment that make up the microbiome. In the microbiome, microbes not only communicate with each other, but also with the rest of our body.
