The first edition of Veterinary Clinical Parasitology was published in 1948 and has been used since that time by students, veterinary practitioners and others as an aid in the diagnosis of parasitic infections. Since 1994, it has been published under the auspices of the American Association of Veterinary Parasitology (AAVP) with the proceeds going to support student travel to the AAVP annual meeting. This sponsorship has not only supported development of more than one generation of veterinary parasitologists, but has also involved a community of parasitologists in the production of the book. The relationship with AAVP continues with the 9th edition. Also, as with past editions, this edition focuses on morphologic identification of parasites, which continues to be widely used in veterinary medicine, increasingly in combination with molecular or immunologic techniques.

There are also some new features in the 9th edition. We have added a chapter summarizing information on modern parasiticides. Additionally, preceding the photographs of parasites for each common domestic animal in Chapter 1there is a table listing current U.S. label‐approved treatments for many parasitic infections. We have also added another new chapter called Diagnostic Dilemmas. In this chapter we present challenging clinical scenarios and diagnostic results and allow the reader to make a diagnosis. A discussion of each of these scenarios is available on the accompanying website of the book.

The 9th edition also marks changes in the authorship of Veterinary Clinical Parasitology . This is the final edition that will be authored by Dr. Anne Zajac (author since the 6th edition) and Dr. Gary Conboy (author since the 7th edition). Drs. Susan Little and Mason Reichard, who joined as authors for this edition, will guide the book going forward and continue its association with AAVP.

As ever, we are very grateful to the members of the American Association of Veterinary Parasitologists (AAVP) and others who have provided material for Veterinary Clinical Parasitology . Since the early 1990s appeals for photographs distributed through the AAVP listserv have brought responses from around the world.

We would also like to particularly acknowledge the extensive contributions to this edition of three of our veterinary parasitology colleagues, Dr. Mani Lejeune, Cornell University; Dr. Yoko Nagamori, Zoetis Corporation (formerly of Oklahoma State University); and Dr. Heather Walden, University of Florida, who graciously offered their magnificent photo collections for our use.
