  • Study: Not All WNV Vaccines Render Same Immune Response

    When it comes to getting shots, a single needle prick might seem like a better idea compared to multiple pokes. But when it comes to your horses' West Nile virus (WNV) vaccinations, multiple injections might be the way to go: Researchers recently tested horses' serologic (blood) response to six WNV vaccination regimens and found some significant d...

  • Study Confirms Horses Respond to Negative Reinforcement

    If we train our horses correctly, we should sense that they get “lighter” as training progresses. In other words, we should be able to execute cues with less force and get the same result. But until now, measuring that “lightness” has always just been a matter of “feeling,” so to speak: Danish researchers have put the s...

  • Equine Emerging Diseases Reviewed

    Tracking emerging and re-emerging equine diseases helps the horse world attempt to stay a step ahead of economically devastating and deadly outbreaks. For that reason, equine veterinarians and industry members gathered on June 14, for Merck Animal Health’s "Equine Emerging and Re-emerging Disease Luncheon" at the 2013 American College of V...

  • Study: Some Wobbler-Affected Thoroughbreds Can Race

    Cervical vertebral malformation (CVM) is considered, by some, a diagnosis that leaves a horse with little hope of an athletic career. But according to recent study results, some carefully managed CVM horses could have a productive future ahead of them, after all.

  • Vitamin E Supplementation for Neurologic Disorders

    Veterinarians frequently suggest supplementing the diets of horses with certain neurologic disorders with vitamin E. But why? What disorders does it help? And which of the eight types of vitamin E supplement is most beneficial? Fortunately, it's not quite as complicated as it might seem.

  • Wobbler Syndrome in Older Horses

    The neurologic condition cervical vertebral stenotic myopathy (CVSM, commonly known as wobbler syndrome) is much less common in older horses than it is in young, growing animals. But according to one clinician, this condition should be on all veterinarians' differential diagnoses list when evaluating an aged horse presenting with neurologic signs and/...

  • Triaging Acute Equine Neurologic Emergencies

    A horse owner's day can go from great to horrific in a matter of seconds if he or she arrives at the barn to find their charge either staggering around the field or completely unable to rise. A prompt call to the veterinarian is warranted in these scenarios, but what should an owner expect when the veterinarian arrives?

  • California Authorities Seek Six Horses for EIA Testing

    Agricultural authorities in California are seeking six animals to receive follow-up testing in connection with a California Department of Food and Agriculture (CDFA) Animal Health Branch study of equine infectious anemia (EIA) infections in racing Quarter Horses.

  • EPM-Causing Organisms Widespread in U.S. Horses (AAEP 2012)

    The neurologic disease equine protozoal myeloencephtalitis (EPM) is caused by two protozoal agents, Sarcocystis neurona and, less commonly, Neospora hughesi. While researchers have long understood S. neurona's life cycle and transmission, their understanding of N. hughesi is less concrete. To compare the two organisms, a research team from California ...

  • New Ponazuril Loading Dose Examined for EPM Treatment (AAEP 2012)

    Veterinarians have been treating equine protozoal myeloencephalitis (EPM) with ponazuril (Marquis) since the Food and Drug Administration approved the antiprotozoal in 2001 but, as with any pharmaceutical approach to disease, fine-tuning an effective treatment protocol is always a work in progress. In laboratory studies scientists have shown ponazuril mus...

  • 2012 Equine WNV, EEE Case Totals Steady

    Although they've increased since last update, the number of confirmed equine West Nile virus (WNV) and Eastern equine encephalitis (EEE) cases has steadied, according to the Animal and Plant Health Inspection Service (APHIS) disease maps.

  • Snakes Linked to Spread of Equine Encephalitis Virus

    A horse, mosquito, and snake walked into a bar. The bartender looks up and says, "Is this some kind of joke?" Turns out, the bartender knows those three animals shouldn't be fraternizing because he read a recent article by Thomas Unnasch, PhD, proving snakes can harbor Eastern equine encephalitis virus (EEEV) and could play an important role...

  • Equine Protozoal Myeloencephalitis: Past and Present

    Equine protozoal myeloencephalitis (EPM) continues to frustrate North American horse owners and veterinarians as one of the most common neurologic diseases in horses--and one of the most challenging to diagnose and treat. At the 2011 Western Veterinary Conference, held Feb. 20-24 in Las Vegas, Nev., Steve Reed, DVM, Dipl. ACVIM, of Rood & Riddle Equin...
