Notice
Veterinary medicine is an ever-changing field. Standard safety precautions must be
followed, but as new research and clinical experience broaden our knowledge, changes in
treatment and drug therapy may become necessary or appropriate. Readers are advised to
check the most current product information provided by the manufacturer of each drug to be
administered to verify the recommended dose, the method and duration of administration,
and contraindications. It is the responsibility of the licensed prescriber, relying on experience
and knowledge of the patient, to determine dosages and the best treatment for each
individual patient. Neither the publisher nor the author assumes any liability for any injury
and/or damage to persons or property arising from this publication.

Dedication
To my parents, Joe and Bettie Songer. With me and their other children,
they have been uncompromisingly insistent upon achievement according to
ability, and have settled for nothing less in their own lives. I saw early in life
the value of this as a personal philosophy, learning only later the cost of
living it in daily practice. I admire them for their persistence through thick
and thin.

To Professor Gerald Wilt, Auburn University College of Veterinary
Medicine, my major professor, mentor, and friend. His love for veterinary
bacteriology was contagious. I also owe a debt of gratitude to my mother,
Doris Weden, for her life of love and support.

Preface
Seventy years ago, Hans Zinsser said that infectious disease “is merely
a disagreeable instance of a widely prevalent tendency of all living
creatures to save themselves the bother of building, by their own
efforts, the things they require” and that it “remains one of the few
sporting propositions left for individuals who feel the need of a certain
amount of excitement. It is one of the few genuine adventures left in the
world. The dragons are all dead, and the lance grows rusty in the
chimney corner.”1 Microbiologists seldom speak of their work in such
literary terms, but if pressed (or, in some cases, sufficiently plied with
drink), most would accept the truth of the concept.
Infectious diseases in domestic animals have been documented, with
greater or lesser clarity, for millennia. One of our professors told us that
the first veterinary school was founded centuries ago specifically to deal
with what we now know as contagious bovine pleuropneumonia. This
may be apocryphal, but I hope it is true, if only because it strengthens
my argument: veterinary infectious diseases, old and new, are
constants, despite changes in animals and their genetics, changes in
production methods, better understanding of the need and methods for
sanitation, and development and application of vaccines and
antimicrobials.
From Pasteur’s crude (by today’s standards) but nonetheless elegant
work with anthrax and fowl cholera to the molecular pathogenesis and
cellular microbiology practiced now in so many veterinary
microbiology laboratories, discoveries by veterinary microbiologists
have been applied to improving animal production and welfare and to
providing a safer and more plentiful source of food for humans. Our
motivation for writing this book is the desire to provide a tool, based
upon our experiences in diagnostics, research, and clinical medicine, for
use by the next generation of veterinarians and microbiologists. We
have lived our professional lives in veterinary bacteriology and
mycology, and “we love it platonically˙.Éand have sought its
acquaintance wherever we could find it”1 We hope that others will as
well.
We have put our best efforts into ensuring the accuracy of the content
of this book. Wherever possible, we have updated the taxonomy of the
various bacteria and fungi. We have attempted to include the latest
information about pathogenesis and diagnosis, with allowances for the
primary context of this book, which is in the microbiology curriculum
of veterinary colleges. We welcome the critical comments and
especially the effusive praise of our readers.
