It’s a ratio of 10:1 meaning that human beings are 90% microbial and only 10% mammalian. There are approximately 7000 different species of microbe within the intestine, approximately 700 different species within the mouth, approximately 300 – 400 different species within the vagina, and approximately 700 different species within and found upon the skin.
