Causes of Sudden Death in Racehorses Examined

Sometimes racehorses collapse on the track for reasons that are not immediately apparent; these exercise-related sudden death cases are uncommon and "poorly understood," according to an international team of researchers that recently completed a retrospective study on the subject. They noted that veterinarians are only able to determine the actu...

Horse Sedation with an Oral Gel (AAEP 2010)

We've all heard about or witnessed horses that simply refuse to be restrained long enough for the veterinarian to administer a much-needed intravenous sedative. Authors of a recent study suggest that a sedative-containing gel might be just what the doctor ordered in these cases.

Horse Colic Prognosis Using Blood Lactate Levels (AAEP 2010)

Monitoring lactate levels in samples of peritoneal fluid, the fluid surrounding and lubricating the abdominal organs, can help a veterinarian predict which colicky horses require surgery. John G. Peloso, DVM, MS, Dipl. ACVS, presented a study on peritoneal lactate levels and colic prognoses at the 2010 American Association of Equine Practitioners conventi...

Colic Surgery and Intestinal Lubricants (AAEP 2010)

Colicky horses that undergo exploratory surgery and are ultimately diagnosed with an ileal impaction appear to benefit from a single injection of carboxymethylcellulose (CMC) into the ileum to resolve the problem, according to veterinarians from Auburn University's College of Veterinary Medicine.

Comparing Bute and Firocoxib Safety (AAEP 2010)

The non-steroidal anti-inflammatory drug (NSAID) firocoxib had fewer side effects than phenylbutazone in horses after 42 days of treatment, according to scientists from Merial Limited who presented comparative research results at the 2010 Convention of the American Association of Equine Practitioners (AAEP), held Dec. 4-8 in Baltimore, Md.

R. Equi: The Hunt for New Antibiotics Continues (AAEP 2010)

It isn't for lack of effort that the equine industry still doesn't have new options for treating Rhodococcus equi pneumonia in foals. According to Noah Cohen, VMD, MPH, PhD, Dipl. ACVIM, professor of equine medicine at Texas A&M University, he and his colleagues are well aware that veterinarians are in dire need of better antibiotic alternativ...

Infectious Respiratory Disease: PCR Testing Suggested (AAEP 2010)

Polymerase chain reaction (PCR) is a fast, accurate, quick, and easy testing method to diagnose pathogens associated with equine upper respiratory tract infections, and researchers on a recent study recommended that veterinarians pursue PCR in cases of infectious upper respiratory disease. Not only does it allow the veterinarian to pinpoint the causative ...

Anesthesia for Donkeys vs. Horses (AAEP 2010)

"Donkeys are becoming more common patients for equine veterinarians, and although it is tempting to treat a donkey like a horse, there are important differences regarding patient handling and drug dosages," cautioned Lori Bidwell, DVM, of Lexington Equine Surgery and Sports Medicine in Kentucky. Bidwell spoke on the key differences between anest...

XY Sex Reversal in Horses: The Genes Behind the Switch

Veterinary researchers have taken a leap forward in explaining XY sex reversal, the most common equine sex chromosome abnormality. A team of scientists from the University of Kentucky's Gluck Equine Research Center and the College of Veterinary Science at Texas A&M University have been examining the Y chromosome to determine what prompts a genetic...

Surgical Methods for Angular Limb Deformities Assessed (AAEP 2010)

Angular limb deformities (ALDs) of the carpus (knee) are a common problem in foals and yearlings, and researchers have narrowed the surgical treatment options down to the two that present the best results. Eric R. Carlson, DVM, an equine surgery resident at the University of Illinois' Veterinary Teaching Hospital, gave a presentation on these options ...

Australian Horse Deaths Under Investigation

According to a news story originally posted by British magazine Horse and Hound, the deaths of 40 horses--which occurred between March and June--residing on five different farms in Queensland, Australia, remain under investigation. Australian veterinarians have told reporters that they suspect the culprit is a tropical plant of, or related to, the species...

New Stem Cell Technology Offers Promise to Lame and Injured Horses

In the not-so-distant future, researchers believe they will be able to genetically modify stem cells to create a “vaccine,” so to speak, to treat a large number of musculoskeletal and other disorders in both humans and horses. An Italian research group has made recent strides in further understanding the potential of using stem cells derived f...

NSAIDs Help Pain But Not Bone Healing

Imagine sustaining a fracture or undergoing orthopedic surgery and being prescribed a drug that helps control pain and inflammation. This medication is a non-steroidal anti-inflammatory drug (NSAID). But there is a catch: the drug that helps control your pain inhibits bone healing.

Piroplasmosis: Texas Outbreak Reaches 409

As of Oct. 8 more than 2,300 horses associated with the Kleberg County, Texas, piroplasmosis outbreak have been tested for the disease, and 409 have turned up positive--only one more since the previous report from the USDA to the World Organization for Animal Health on Aug. 25, 2010.

Potential Biomarker for Tying-up Found

In an equine study using "proteomic" technology that systematically analyzed the proteins in skeletal muscle biopsies, a research team from The Netherlands identified a form of the protein creatine kinase that could be a marker for acute tying-up in horses.

PreveNile West Nile Virus Vaccine Recalled

In a letter to veterinarians dated April 28, Brett Whitehead, Director, Equine and Ag Retail Business, of Intervet Schering-Plough Animal Health, encouraged practitioners to return all PreveNile vaccine. The recall was initiated after an increased incidence in the number of adverse events following vaccination with currently marketed serials of PreveNile.

Oral Steroids Beneficial for Horses with Airway Disease

For the first time, researchers have demonstrated that the corticosteroid prednisolone improves the lung function of horses with recurrent airway obstruction, even in the presence of continuous exposure to antigens. The same study also revealed that a low dose of a similar drug, dexamethasone, reversed airway obstruction despite continues antigen exposure.

Researchers Track Lawsonia intracellularis Spread

Lawsonia intracellularis is being forced out of hiding and its secrets extracted largely because of the intense research efforts of scientists like Nicola Pusterla, DVM, PhD, Dipl. ACVIM, and his colleagues at the University of California, Davis, and the University of Minnesota, St. Paul.
