Saskatchewan Vet College Back In Action

Saskatoon’s Western College of Veterinary Medicine resumed equine services at its Large Animal Clinic June 29.

The University of Saskatchewan-based veterinary college voluntarily suspended equine clinical services June 21 following a confirmed diagnosis of equine herpes virus, Type 1 (EHV-1) in a Saskatoonarea horse brought to the clinic June 18.

That horse, which was euthanized June 19 due to the severity of its illness, has since been confirmed as having had the neurologic form of EHV-1, also known as equine herpes virus myeloencephalopathy (EHM).

Since that time, none of about two dozen horses housed in or outside the Large Animal Clinic have shown clinical signs of EHV-1 and all have tested negative for the disease, the college said in a release.

Clinical teams will keep using safeguards, such as screening for all equine patients for clinical signs of EHV-1, before admitting any animal to the clinic,” said Dr. Chris Clark, a specialist in internal medicine at the college.

Nearly all horses are exposed to EHV-1 during their lifetime and infected horses can come down with mild respiratory disease, but in rare cases, EHV-1 can affect a horse’s brain and spinal tissue, causing EHM. The virus is “highly contagious” among horses and camelids such as alpacas and llamas, but not transmissible to humans or other animal species, the college said.

The infected Saskatoonarea horse wasn’t yet known to have any connection to cases of EHV-1 which have spread through various provinces and states in the past six weeks. Those cases were linked to horses that attended or were in contact with other animals that competed at a national cutting horse competition at Ogden, Utah.

Several cases in Alberta and a separate case in southeastern Saskatchewan were linked to a cutting horse competition last month at Lloydminster. Those cases are also believed to have stemmed from the Utah competition.
