Highly recommended. Angela Douglas has produced a book of great scholarship, clarity, and intelligence--and with the loving touch of a biologist. Douglas has much to teach students and experts alike."--Martin J. Blaser, author of Missing Microbes: How the Overuse of Antibiotics Is Fueling Our Modern Plagues "This ambitious book surveys animal-microbe associations and reimagines the animal as a multi-organismal being. Douglas nicely balances conceptual points and detailed examples, making the text both accessible to anyone with a basic background in biology and interesting to specialists in symbiosis and microbiome science. Fundamentals of Microbiome Science is a very enjoyable read."--David Berry, University of Vienna "A very significant contribution to the emerging field of animal-bacteria symbiosis. I am not aware of any other book that covers this topic so exhaustively and in such an integrated, up-to-date, and comprehensive manner."--Francois Leulier, Centre National de la Recherche Scientifique, Paris
