This advanced textbook provides a unique overview of the microbial communities (normal indigenous microbiota) inhabiting those regions of the human body that are exposed to the external environment, including the skin, eyes, oral cavity and the respiratory, urinary, reproductive and gastrointestinal tracts. In order to understand why particular organisms are able to colonise an anatomical region and why the resulting microbial community has a particular composition, an ecological approach is essential. Consequently, the key anatomical and physiological characteristics of each body site are described throughout the book. The crucial roles of the indigenous microbiota in protecting against exogenous pathogens, regulating the development of our immune system and mucosae, and providing nutrients are also discussed. The involvement of these organisms in infections of healthy and debilitated individuals are discussed throughout and methods of manipulating the composition of the indigenous microbiota for the benefit of human health are also described.

‘This authoritative book fills a gaping hole in the literature by describing how bacteria interrelate with us … The book's strength lies in the exhaustive, clearly organized evidence that the author presents to overwhelmingly document his hypothesis … His hard-nosed look at the evidence in the area of holistic medicine will be much appreciated by the skeptic and the enthusiast alike … He has made a valuable contribution by assembling in one place this comprehensive body of information.‘

‘This is the first edition of this text book that gives an overview of the microbial inhabitants of the regions of the human body exposed to the external environment, including the skin, eyes, oral cavity and the respiratory, urinary, reproductive and gastrointestinal tracts. It is aimed at advanced students of microbiology, medical microbiology, microbial ecology and human biology … The test definitely makes for an interesting read and is well written, well referenced and has good diagrams, pictures and clear tables. The final chapter 'Manipulation of the indigenous microbiota using environmental determinants', is an interesting description of how infections may, in theory at least, be treated without antibiotics. Given the increasing microbial resistance problems that challenge daily practice, these concepts inevitably promote interest amongst microbiologists.‘
