Equine respiratory disease is no fun for horse or owner, and it can have a significant economic impact on the performance horse industry in both cost of treatment and in training and performance days lost.
Since it was first identified in 2007, deadly equine multinodular pulmonary fibrosis (EMPF) has been reported in numerous horses across North America and Europe. While still considered a rare disease, EMPF appears to be related to a very common one—equine herpesvirus (EHV)—and early treatment appears to be the main hope for survival.
Even though they're small in stature, foals can have some big health problems. And researchers around the world are continually working to better understand these health problems and find more effective ways to treat them. At the 2013 Society for Theriogenology Conference, held Aug. 7-10 in Louisville, Ky., Chris Sanchez, DVM, PhD, Dipl. ACVIM, associ...
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...
Imagine horses with recurrent airway obstruction (RAO, or more commonly heaves) wearing Darth Vader-like masks and breathing in corticosteroids every day sun, rain, or snow. That was essentially the scene at at the Université de Montréal in Quebec, Canada, during a yearlong study investigating the effect of inhaled corticosteroids (ICS) and ...
No two lungs are exactly alike—especially when it comes to equine airway disease. According to French researchers, when investigating lung conditions using bronchoalveolar lavage (BAL), ensure you’re checking both lungs in the process.
The Ontario Racing Commission (ORC) has lifted restrictions placed on horses residing in Barn 3 at Woodbine Racetrack, and horses not stabled in Barn 1 are now permitted to leave the property, said ORC Manager of Veterinary Services Adam Chambers, BVMS.

Flu season for horses can be any season. And considering that even horses vaccinated against the equine influenza virus (EIV) can still “catch the flu,” this disease is cause for concern. A group of Japanese researchers, however, recently evaluated a flu inhibitor in horses and found that it could help EIV-infected animals recover more quickly.
When a horse contracts a disease, the owner or caretaker usually focuses solely on getting the horse healthy again and protecting others on the farm from illness. But in reality, certain ailments could have community-, region-, and even industry-wide effects. For instance, an equine viral arteritis or contagious equine metritis outbreak could shutter the ...
The American Horse Council and the American Association of Equine Practitioners issued an open letter to the horse industry March 28 regarding equine disease outbreaks in the United States. In their communication, the organizations outline current horse health issues facing the industry and seek equine community participation in developing a National Equi...
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?
Veterinarians often choose upper airway endoscopy when working to diagnose equine arytenoid chondritis--an uncommon but problematic respiratory condition--but in some cases a definitive diagnosis lies out of reach. Ultrasonography could offer a valuable adjunct tool for diagnosing this respiratory condition, however, especially in cases lacking a definiti...
We often talk about the horse world in the national context, but at the global level the World Organization for Animal Health (OIE) assists to protect our horses and the horse industry from infectious disease and to put regulations in place for safe trade and transport between countries.
Infectious respiratory diseases such as equine influenza and equine herpesvirus can have a significant welfare and economic effect on the horse industry, and researchers and veterinarians have devoted much time and money to trying to control and prevent outbreaks. Far less is known, however, about another infectious respiratory disease: equine rhinitis vi...

A team of researchers from the University of California, Davis (UC Davis), recently tested if idiopathic headshaking in horses could be similar to a condition in humans--trigeminal nerve pain caused by the reactivation of a latent virus.
In recent years it seems owners and practitioners are increasingly confronted--both directly and indirectly--with cases of equid herpesvirus-1 myeloencephalopathy (EHM).
British racehorse trainer Victor Dartnall is currently dealing with an outbreak of neurologic equine herpesvirus-1 (EHV-1) at his yard in North Devon, England.
Two horses are in stable condition while being treated for neurologic equine herpesvirus-1 (EHV-1) at the University of Minnesota (UM) Large Animal Hospital, according to the treating clinician. Both animals--who reside at the same Wright County, Minn., farm--have tested positive for the virus since being admitted to the clinic this week. A third horse (t...
Editor's Note: This article is part of TheHorse.com's ongoing coverage of topics presented at the British Equine Veterinary Association's 51st annual Congress, held Sept. 12-15 in Birmingham, UK.
One of the most controversial topics in Thoroughbred racing today is the race-day use of furosemide (commonly called Salix or Lasix). The drug is used to lessen the effects of a respiratory condition called exercise-induced pulmonary hemorrhage (EIPH), characterized by bleeding into the lungs or out the nose during exercise. In the midst of rumor and fact...
For athletic horses sporting increasingly popular nasal strips, the phrase "winning by a nose" carries new meaning. Research studies evaluating these accessories' efficacy, however, have produced mixed results.
The neurologic form of equine herpesvirus-1 (EHV-1, also called myeloencephalopathy) is highly contagious and multiplies within its host very rapidly, making early detection and prompt treatment paramount goals in disease control.
