Respiratory diseases are among the most common medical conditions encountered in equine practice. They occur in horses of all breeds and ages, and can have a devastating impact on a horse's health – anorexia, abortion, facial deformities and pneumonia are to name but a few of the consequences.
This book brings all the major equine respiratory diseases together in one single concise volume. Written by two leading equine experts, it enables the reader to relate clinical anatomy, physiology and pathology to clinical signs seen, and to form a rational basis for the control, treatment and prevention of respiratory diseases. Essential reading for all those working in or studying equine medicine, Equine Respiratory Diseases also includes:
Diagnostic tests for infectious and non-infectious respiratory disease
Details of techniques involved when testing for respiratory diseases
Step-by-step practical instructions for carrying out procedures
Numerous colour pictures
Dr Rush gained her DVM degree from The Ohio State University in 1989. She completed her internship training at North Carolina State University in 1990, and her internal medicine residency training at The Ohio State University in 1993. She has been awarded the 1996 and 2003 Carl J. Norden Distinguished Teacher Award and the 2002 Pfizer Award for Research Excellence at Kansas State University. Dr. Rush's research interest is equine respiratory disease, particularly respiratory physiology, immunology, and aerosol drug therapy. Her clinical interest is in equine respiratory, neurologic, and immune-mediated disease.
