Microbiology A Systems Approach by Marjorie Kelly Cowan, Heidi Smith
Welcome to the microbial world! I think you will f ind it
fascinating to understand how microbes interact with us, and with
our environment. The interesting thing is that each of you has
already had a lot of experience with microbiology. For one thing, you
are thoroughly populated with microbes right now, and much of your
own genetic material actually came from viruses and other microbes.
And while you have probably had some bad experiences with quite a
few microbes in the form of diseases, you have certainly been greatly
benef ited by them as well.
This book is suited for all kinds of students and doesn’ t require
any prerequisite knowledge of biology or chemistry. If you are
interested in entering the health care profession in some way, this
book will give you a strong background in the biology of
microorganisms, without overwhelming you with unnecessary details.
Don’ t worry if you’re not in the health professions. A grasp of this
topic is important for everyone—and can be attained with this book.
