Antimicrobial drugs in veterinary medicine have made a dramatic improvement in the health of our horses, but it’s alarming when infections do not respond to these drugs. “It is not a new phenomenon, but there has been ever-growing concern about antimicrobial resistance.”

The Milne Lecture at the American Association of Equine Practitioners (AAEP) Convention is also known as the State of the Art Lecture because each Milne Lecture, regardless of topic, is selected for its groundbreaking qualities and potential to change the paradigms by which veterinarians and researchers understand that topic in the horse. This year’s Milne Lecture (which is named for Frank J.

Bone does not heal, incorporating the scar tissue as seen in most all other tissues–it regenerates itself. It changes its shape and structure based on its use, and if broken can resume 100% of its former strength and function.

At least two Iowa horses have been euthanized after battling what officials believe might be the neurologic form of equine herpesvirus type 1 (EHV-1). According to Iowa State Veterinarian John Schiltz, DVM, officials know of only one premise possibly affected by the virus, where these two horses lived. “Some of the preliminary tests have come back negative, but the definitive testing is

Equine researchers at Colorado State University’s James L. Voss Veterinary Teaching Hospital are developing a faster and simpler test to determine a horse’s exposure level to strangles. Currently, tests exist only for horses with active signs of disease.

The test method is an enzyme-linked immunosorbant assay (ELISA) test, which would provide veterinarians with a tool to quickly

A 2,000-pound Belgian gelding named Janyck (pronounced Yanick) has nearly recovered after a dramatic rescue from a frozen pond on Feb. 13. The 18-hand, 7-year-old’s misadventure took place in Woolwich Township, N.J.

Fractures of the distal phalanx (also known as P3 or the coffin bone) are common, especially in racehorses, noted Tara S. Rabuffo, DVM, of the University of Pennsylvania’s New Bolton Center. She and her colleagues reviewed case records and all related diagnostic materials on 73 racehorses (26 Thoroughbred and 47 Standardbred during an 11-year period) admitted to the George D. Widener Hospital

Veterinarians have a variety of ways to look inside your horse to see what might be bothering him. One of these methods is gastroduodenoscopy, which allows the veterinarian to see the interior of the esophagus, stomach, and duodenum with the use of a gastroscope.

The USDA has issued a full license to Fort Dodge Animal Health for its West Nile virus (WNV) vaccine that has been distributed under a conditional license since August of 2001. Results of efficacy studies completed and submitted to the USDA qualified the vaccine for full licensure. According to Tom Overbay, DVM, director, Field Veterinary Services at Fort Dodge, 95% of horses vaccinated with

A small outbreak of equine herpes at Penn National Racecourse has prompted management of Philadelphia Park to bar horses shipping in to race as well as horses shipping out to “race and return” from the Grantville, Pa. oval.

Richard Schnaars, general manager of Penn National, stressed that the situation is “very localized,” with only two horses from the stable of trainer Bob Wolfe
