Microbiome: The Universe Inside You

By: Priestley, Helene

From the time we're born, we acquire bacteria, fungi, viruses, and other microbes from other people, everything we touch, and everything we eat. This makes up what some call a super-organism: The human microbiome. It includes 10 to 100 trillion microbial cells on and in the human body. The most well-known part of the human microbiome and its vital ecosystem's role in human health.

This highly visual exploration is a fascinating look at the still-mysterious human microbiome--the viruses, bacteria, fungi, and other microbes that work together to play an essential role in keeping humans healthy. The accessible text allows full-bleed images to shine throughout, including full-spread, photo-realistic illustrations that bring the world of microorganisms to life.

Written by Helene Priestley, who holds a PhD in molecular biology, the author created the book in cooperation with Dr. Purna Kashyap, director of the Microbiome Program, a Mayo Clinic research initiative that studies the microbiome's role in health. Dr. Kashyap also gives readers tips and tricks for keeping their microbiome healthy.
