Western College of Veterinary Medicine WCVM horse bacteria equine asthma, equine chronic obstructive pulmonary disease (COPD), horse heaves

Veterinary researchers at the Western College of Veterinary Medicine (WCVM) in Saskatoon, Saskatchewan are investigating whether certain bacterial populations in a horse’s windpipe can contribute to RAO, or heaves. Motivated by human research on asthma and chronic obstructive pulmonary disease (COPD), large animal internal medicine specialist Dr. Katharina Lohmann has developed the airway microbiome project.

horse heaves, equine heaves, horse lungs, equine lung disease

Heaves is a chronic, non-infectious lung disease that primarily affects mature horses and can have a significant effect on a horse’s well-being and performance ability. Heaves is also referred to as recurrent airway obstruction (RAO) and is often compared to human asthma. The primary pathologic mechanisms leading to clinical signs in affected horses are bronchospasm, inflammation and thickening of the lower airways (small bronchi), and accumulation of mucus and inflammatory exudates in the airway lumen. The term RAO indicates that the disease is chronic and recurrent, although “remission” from clinical signs can be achieved through treatment and proper management of affected horses.

Researchers at the University of Guelph have made an equine breakthrough that can change the health of newborn foals. Led by John Prescott, pathobiology researcher and former professor, the research team identified an uncommon, but deadly bacterium that causes necrotizing enteritis disease in very young foals, and has already created a vaccine for further research. For years, an unknown strain of this intestinal bacterium has been killing foals within the first week of life. Prescott and his team have worked for several years to understand the cause of necrotizing enteritis in foals and recently identified the bacterial agent and its deadly toxin, which they have called NetF.

When an equine athlete experiences an episode of laminitis or founder it can be a painful experience. While there are numerous studies and articles on the causes of these two maladies, there is also a general consensus on what the hoof capsule experiences after the episodes occur. When a horse experiences a bout of laminitis, whether through injury, overfeeding, or metabolic issues, inflammation of the laminae occurs. The anatomy of the hoof is such that the insensitive laminae are attached to the hoof wall and the sensitive laminae are attached to the coffin bone.

Equine Tying Up Syndrome, pssm, rer, polysaccharide storage myopathy recurrent exertional rhabdomyolysis Fabienne Uehlinger Western College of Veterinary Medicine WCVM

There are two simple words that describe painful, exercise-associated muscle cramping in a horse: tying up. While the traditional tying up usually occurs after a long hard ride, some horses can tie up repeatedly for no immediately obvious reason. Regardless of the underlying cause, the clinical signs are similar. And in most cases, affected horses require immediate veterinary care, says Dr. Fabienne Uehlinger of the Western College of Veterinary Medicine (WCVM) in Saskatoon, Saskatchewan.

Equine Pain, horse pain, grimaces score, equineguelph, grimace pain scale

Hiding pain is one of the top survival skills of the horse. An important part of horse ownership is learning to recognize the signs a horse may be in discomfort rather than dismissing certain subtle cues as just bad behaviour. Earlier this year, Dr. Brianne Henderson gave a well-received lecture to a room full of horse owners in Hillsburgh, ON. The attendees were interested in ensuring the welfare of their equine companions by honing their skills for detecting pain.
