The Microbiome in Numbers

• There are 100 trillion bacteria and other microorganisms in/on our entire body.

• Ninety percent of the microbiome is concentrated in the large intestine.

• The weight of the microbiome throughout the body amounts to 5.6 pounds.

• There are more bacteria in the palm of our hand than there are people on the planet!

• The bacteria on our right hand is different from that of our left hand - only ⅙ of the bacteria are alike.

• Bacteria are the most ancient inhabitants on earth: they have existed for 3.5 billion years, long before humans, dominating every corner of the world. It’s no surprise that as other creatures developed, they collaborated with them.
