The backstretch of Parx Racing in Bensalem, Pa., was placed under quarantine Friday afternoon after a horse stabled there became ill. During the quarantine, horses will be allowed to ship to Parx, but no horses will be allowed to leave the grounds.
A horse trained by Ramon Martin spiked a fever on Tuesday and was sent to the Mid-Atlantic Equine Center in Ringoes, N.J. According to Rodney Belgrave, the center's director of internal medicine, the horse was tested with a nasal swab and was determined to have the non-neurological strain of the equine herpesvirus.
