EVA Vaccines: What You Need to Know

Some equine diseases come and go with little impact on the horse industry as a whole. Others affect only local or state industries when they rear their ugly heads. But when a disease has the potential to shutter the global horse breeding industry, controlling it becomes crucial. One of those diseases is equine viral arteritis (EVA). Fortunately, veterinar...

EVA: A European Perspective

An infectious equine disease is bad news no matter what language you speak or which country you call home. But between countries, regulatory bodies, and animal health professionals, there often remains a difference in perspective when it comes to handling these diseases.

Equine Infectious Disease Outbreak Response 101

From equine herpesvirus and influenza to strangles and coronavirus, infectious diseases can cause quite a stir in the horse industry—quarantines, canceled competitions, and, in some cases, even horse deaths or the threat of human infection. And something all horse owners and veterinarians should know is how to respond in the face of an infectious di...

Placentitis Could be Detected Early with Hormone Testing

Equine placentitis is subtle in its onset, often causing the death of its victim—the unborn foal—before veterinarians can detect and treat it. Equipping veterinarians to identify these cases of placental infection early could help them prevent abortions, lost time on the breeding calendar, and the general heartbreak that can come with losing a...

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...

Can Vaccination Protect Horses from Neurologic EHV-1?

In the equine industry three simple letters, when said in order, can silent a room of horsemen, turn a showground into a ghost town, and send shockwaves through barns. They're E, H, and V, and they stand for equine herpesvirus-1, a contagious equine virus that can cause serious neurologic problems in affected horses. Fortunately for owners, veterinari...

Veterinarians Making Progress on National Equine Health Plan

Equine herpesvirus myeloencephalopathy (EHM) put dozens of show horses at risk for infection after they were exposed to a sick horse at a single competitive event in Utah in 2011. Unaware of the exposures, owners of these horses dispersed the show animals to 19 states and several Canadian provinces, unleashing the potential to infect others in epidemic pr...

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 Placentitis Update

What's the most common cause of late-term abortion in horses and remains challenging for veterinarians to diagnose and treat, despite ongoing research? If you said placentitis, you're right. To bring attendees of the 2013 Society for Theriogenology Conference, held Aug. 7-10 in Louisville, Ky., up to speed on the latest research on the complex top...

Top Foal-Related Studies of 2012-'13

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...

Botulism in Horses: An Update

Rising hay prices and the financial crunch caused by 2009's Great Recession drove many horse owners to seek less expensive forage sources, including large round bales, haylage, and silage. But according to Amy Johnson, DVM, Dipl. ACVIM, compromising on hay quality and feeding from half-ton bales led to a larger problem: an uptick in reported cases of ...

Drug Peramivir Could Help Horses Suffering from Flu

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.

AAEP, AHC Partner to Prevent Equine Disease Outbreaks

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 ...

AHC, AAEP Issue Letter on Equine Disease Outbreaks

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...

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?

New Test Could Detect Equine Lyme Disease Sooner (AAEP 2012)

Diagnosing Lyme disease in horses is tricky business; not all horses that contract the causative bacterium, Borrellia burgdorferi, from infected ticks develop the debilitating condition, and those that do might not show signs until several months after infection. As with many diseases, early detection can mean swifter resolution, along with better recover...

Optimizing Piroplasmosis Treatment Protocols (AAEP 2012)

The tick-borne protozoal disease equine piroplasmosis (EP) impacts horses worldwide, causing hemolytic anemia (the body's immune system attacks and kills its own red blood cells) and even death. Veterinarians' drug of choice for eliminating the causative parasites, Theileria equi and Babesia caballi, is imidocarb dipropionate, which is effective b...
