Shipping horses between Woodbine and Fort Erie racetracks in Ontario, Canada, has been suspended indefinitely while Ontario Racing Commission veterinarians investigate a case of strangles detected in a pony at Fort Erie.
Strangles is a highly contagious disease of the upper respiratory system, caused by the bacterium Streptococcus equi. Symptoms include inflammation of the throat, nasal discharge, and abscesses in the lymph nodes under the jaw.
