Microbiology
5th Edition
Lansing M. Prescott

Prescott, Harley and Klein's 5th edition provides a balanced, comprehensive introduction to all
major areas of microbiology. Because of this balance, Microbiology, 5/e is appropriate for students
preparing for careers in medicine, dentistry, nursing, and allied health, as well as research, teaching,
and industry. Biology and chemistry are prerequisites. The Fifth Edition has been updated
extensively to reflect the latest discoveries in the field.
New to This Edition
_ Every chapter in the book has been updated to reflect the latest discoveries in microbiology, including
information on genomics, biofilms, mechanisms of toxins, classification, and emerging diseases. The most
extensive revision has occurred in the areas of genetics, microbial ecology, and immunology where material
has been updated and reorganized to allow for easier use.
_ New Genomics chapter: Chapter 15. The genetics coverage has been reorganized for clarity and ease of
teaching. The genetics section now ends with a completely new chapter on genomics. New Chapter 28 on
microorganism interactions and microbial ecology!
_ Newly developed art program--much of the art is new or revised! It incorporates color and style consistency
throughout so students will easily identify certain topics.
_ New critical thinking questions have been added to provide practice in analyzing data, predicting outcomes,
and to teach students how to think logically.
_ The general organization of the text has been modified to provide a more logical flow of topics and give
greater emphasis to microbial ecology
Features
_ Prescott's textbook contains briefer chapters than most books, but more of them (42). Students will find the
concise chapters more palatable and less intimidating. Short chapters give the instructor the opportunity to fit
the text more closely to the instructor's syllabus. Topic flexibility is allowed.
_There is an outstanding pedagogical system including outlines, concepts, key terms, cross-referencing,
readings, new critical thinking questions, etc., to help students understand difficult material.

Microbiology is an exceptionally broad discipline encompassing
specialties as diverse as biochemistry, cell biology,
genetics, taxonomy, pathogenic bacteriology, food
and industrial microbiology, and ecology. A microbiologist must
be acquainted with many biological disciplines and with all major
groups of microorganisms: viruses, bacteria, fungi, algae, and protozoa.
The key is balance. Students new to the subject need an introduction
to the whole before concentrating on those parts of
greatest interest to them. This text provides a balanced introduction
to all major areas of microbiology for a variety of students. Because
of this balance, the book is suitable for courses with orientations
ranging from basic microbiology to medical and applied microbiology.
Students preparing for careers in medicine, dentistry, nursing,
and allied health professions will find the text just as useful as
those aiming for careers in research, teaching, and industry. Two
quarters/semesters each of biology and chemistry are assumed, and
an overview of relevant chemistry is also provided in appendix I.
Organization and Approach
The book is organized flexibly so that chapters and topics may be
arranged in almost any order. Each chapter has been made as selfcontained
as possible to promote this flexibility. Some topics are
essential to microbiology and have been given more extensive
treatment.
The book is divided into 11 parts. The first 6 parts introduce the
foundations of microbiology: the development of microbiology, the
structure of microorganisms, microbial growth and its control, metabolism,
molecular biology and genetics, DNA technology and genomics,
and the nature of viruses. Part Seven is a survey of the microbial
world. In the fifth edition, the bacterial survey closely
follows the general organization of the forthcoming second edition
of Bergey’s Manual of Systematic Bacteriology. Although principal
attention is devoted to bacteria, eucaryotic microorganisms receive
more than usual coverage. Fungi, algae, and protozoa are important
in their own right. The introduction to their biology in chapters
25–27 is essential to understanding topics as diverse as clinical microbiology
and microbial ecology. Part Eight focuses on the relationships
of microorganisms to other organisms and the environment
(microbial ecology). It also introduces aquatic and terrestrial
microbiology. Chapter 28 presents the general principles underlying
microbial ecology and environmental microbiology so that the subsequent
chapters on aquatic and terrestrial habitats can be used without
excessive redundancy. The chapter also describes various types
of microbial interactions such as mutualism, protocooperation, commensalism,
and predation that occur in the environment. Parts Nine
and Ten are concerned with pathogenicity, resistance, and disease.
The three chapters in Part Nine describe normal microbiota, nonspecific
host resistance, the major aspects of the immune response,
and medical immunology. Part Ten first covers such essential topics
as microbial pathogenicity, antimicrobial chemotherapy, and epidemiology.
Then chapters 38–40 survey the major human microbial
diseases. The disease survey is primarily organized taxonomically
on the chapter level; within each chapter diseases are covered according
to their mode of transmission. This approach provides flexibility
and allows the student easy access to information concerning
any disease of interest. The survey is not a simple catalog of diseases;
diseases are included because of their medical importance and their
ability to illuminate the basic principles of disease and resistance.
Part Eleven concludes the text with an introduction to food and industrial
microbiology. Five appendices aid the student with a review
of some basic chemical concepts and with extra information about
important topics not completely covered in the text.
This text is designed to be an effective teaching tool. A text
is only as easy for a student to use as it is easy to read. Readability
has been enhanced by using a relatively simple, direct writing
style, many section headings, and an organized outline format
within each chapter. The level of difficulty has been carefully set
with the target audience in mind. During preparation of the fifth
edition, every sentence was carefully checked for clarity and revised
when necessary. The American Society for Microbiology’s
ASM Style Manual conventions for nomenclature and abbreviations
have been followed as consistently as possible.
The many new terms encountered in studying microbiology
are a major stumbling block for students. This text lessens the
problem by addressing and reinforcing a student’s vocabulary development
in three ways: (1) no new term is used without being
clearly defined (often derivations also are given)—a student does
not have to be familiar with the terminology of microbiology to
use this text; (2) the most important terms are printed in boldface
when first used; and (3) a very extensive, up-to-date, page-referenced
glossary is included at the end of the text.
Because illustrations are critical to a student’s learning and
enjoyment of microbiology, all illustrations are full-color, and
many excellent color photographs have been used. Color not only
enhances the text’s attractiveness but also increases each figure’s
teaching effectiveness. Considerable effort has gone into making
the art as attractive and useful as possible. Much of the art in the
