Microbiome [EPUB ebook] 
The Universe Inside You

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 is the gut microbiome, as recent research has revealed this vital ecosystem’s role in human health. 



This highly visual exploration is a fascinating look at the 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.



With a Ph D 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.
