Handbook of Equine Parasite Control

A must–have guide for any equine veterinarian, this is a practical and concise handbook on the control of equine parasites.  It enables you to advise your clients effectively on evidence–based parasite control programs. The first section of the book reviews the basic biology of internal parasites and the factors influencing their transmission. The second section discusses the general principles of parasite control. The third section provides diagnostic and assessment tools for interpreting clinical, historical and laboratory information.  Finally the fourth section contains 20 case studies reflecting the full range of parasites and providing detailed answers and discussions, providing you with the opportunity to practice the application of knowledge and illustrating the concepts of modern parasite control. Handbook of Equine Parasite Control is an invaluable companion for equine veterinary practitioners, veterinary students, equine veterinary technicians and nurses, researchers in equine parasitology, horse owners, and farm and stable managers. KEY FEATURES • Combines practical and research–based experience of parasite control • Grounded solidly in theory while providing practical examples and techniques • Accompanied by clear clinical photographs, line drawings and tables • Written by two veterinarians with over 40 years combined experience working in equine parasitology both in practice and academia.

Craig R. Reinemeyer graduated from the Ohio State University College of Veterinary Medicine in 1976, and spent 5 years in mixed animal practice before returning to OSU to pursue a PhD in veterinary parasitology.  He was a faculty member of the University of Tennessee College of Veterinary Medicine from 1984 to 1998, and served as the President of the American Association of Veterinary Parasitologists from 2003 to 2004.  In 1997, Dr. Reinemeyer founded East Tennessee Clinical Research, a contract research organization that conducts pharmaceutical studies to facilitate the development of new veterinary drugs.  ETCR’s efforts have contributed to the approval of several currently marketed anthelmintics for horses, cattle, and pets.  Martin K. Nielsen is Assistant Professor in the Department of Veterinary Science of the Maxwell H. Gluck Equine Research Center at the University of Kentucky. He has a doctorate from the University of Copenhagen, and was a faculty member there for four years before moving to Kentucky. His research interests include endoparasite infections of horses, clinical and molecular diagnosis, epidemiology, surveillance, and control.

“This book combines classical parasitology with horse sense, making it a very useful tool for all who work with horses. The authors submit all the evidence available regarding the internal parasites of the horse. Practitioners will appreciate the ease with which they can access the information.”  ( Doody’s , 19 July 2013) “This text (handbook) is fantastic. Very thorough, I see where they encompassed many decades of information that is science based and also extremely practical. I see a tremendous amount of Dr. R’s knowledge and style here, again both scientific and practical included in this text. Extremely easy to read and very concise concerning what information equine vets need and should know about equine parasites and the management and use of current dewormers combined with management strategies. Ton more in here than” just deworm your horse every 2 months!.”  ( Steven Grubbs of Boehringer Ingelheim )
