A horse quarantine has been lifted at the Hoosier Park racetrack in central Indiana where two Thoroughbreds tested positive for Streptococcus equi (the bacterium that causes the disease strangles).

Racing manager Jeffrey Smith says no other horses have shown signs of the disease. Smith says the quarantined barn is being disinfected and won’t be used again during the track’s current racing season that ends Oct. 24.

Officials says they’ve had no problems in any of the track’s other 16 barns, where about 1,000 horses are housed
