A 4-year-old filly stabled at Ellis Park in Henderson County, Kentucky, has been diagnosed with strangles. Rusty Ford, equine programs manager for the office of the state veterinarian, said the filly presented June 30 with an elevated body temperature and has since been removed from the grounds and taken to a private quarantine facility near Lexington.

The infected filly is one of 15 horses stabled in trainer Ron Moquett’s barn. Preliminary information suggests the infected filly arrived at Ellis Park from Prairie Meadows June 17, according to Ford.

The remaining horses in Moquett’s barn have been placed under quarantine and will undergo a three-part series of testing to determine if any of those animals are infected. Initial culture tests and pharyngeal washes to determine the status of each horse in the barn were conducted July 7.

Ford said currently none of the horses remaining in the infected barn are showing any signs of illness
