LATEST RESEARCH

Exercise-induced pulmonary hemorrhage (EIPH) refers to bleeding into the airways experienced by some horses while performing high-intense exercise. Since EIPH can bring great medical, economical, and welfare burden to the equine racing industry, research in this area is deemed very important. 

Lyme borreliosis, Anaplasmosis, and Potomac Horse Fever (PHF) are three seasonal infectious diseases affecting the Ontario equine industry. Determining the prevalence of such diseases in different geographical locations throughout the province can give insight on their distribution and associated risk factors.
