Preface ..•••••••••.••••••.•••...................................••.•.••••.............................................•..
In view of the wide range of microbiology texts currently on offer from bookshops, one might reasonably question the need for another. In light
of this, the authors of an entirely new microbiology book have an obligation to explain why they were inspired to make their own contribution.
In writing the present text, we have tried to produce a genuine introduction to the biology of microorganisms, presenting fundamental information and ideas about microorganisms in an understandable, straightforward fashion, without resorting to over-simplification. At the same time, we hope that we have given sufficient, detailed information to inspire the readers to progress to more advanced and specialized texts. These objectives are relatively easy to reach with a book on microbiology, because most undergraduates in biological sciences have a natural interest in the subject, particularly in its applied aspects.
In writing the book we had in mind two particular kinds of readers. We
hope that it will constitute an attractive introduction to students in the early years of a specialist degree or diploma course in microbiology. But we have also written the book for students who are taking courses in a wide range of biological disciplines. Although these readers will not necessarily become microbiologists and do not require the advanced, detailed treatment
of an honours microbiology undergraduate, they do require a sound and concise grounding in the basics of the subject with clear links to microbiological applications. In contrast to many of our competitors, we have
covered all the major groups of microorganisms and resisted the temptation to concentrate only on the bacteria. The emphasis is on those aspects of microorganisms which separate them from plants and animals.
Although an ultimately rewarding experience, preparation of the text has proved difficult and time-consuming. We are indebted to our editor, Dominic Recaldin, whose advice and enthusiasm have been major sources of
encouragement throughout the enterprise. The comments of a number of reviewers were extremely valuable, particularly when we were taking our first tentative steps preparing drafts of the first chapters. I would like to acknowledge Dr Peter Gowland's contribution during the early stages of production. Especially warm thanks go to Jane Faull, Derek Springham and

Steve Ketteridge who contributed chapters on eukaryotic microorganisms,
microbial biotechnology and viruses respectively. 1 am further indebted to Steve Ketteridge for reading the drafts of many of the chapters and for his helpful advice. Finally, I thank my wife, Gerry, for typing a large proportion
of the manuscript, and for her constant encouragement and cups of tea!
