Danedream, winner of last year’s Qatar Prix de l’Arc de Triomphe, a prominent French Thoroughbred race, will likely miss her chance to defend her title in this year’s running Oct. 7 due a positive equine infectious anemia (EIA) test in Cologne, Germany. A horse at the same racing center as the 4-year-old filly recently tested positive EIA, also known as swamp fever, according to the Racing Post. Danedream is trained by Peter Schiergen.

All horses stabled around the German course were placed in lockdown the night of Oct. 1.

Patrick Barbe, spokesman for Danedream’s part owner Teruya Yoshida, told the Post: "The horse that tested positive was stabled far away from Danedream and is not one of Peter Schiergen’s horses. It was only one positive test, and that horse has been removed from the area, but the stables in and around the racecourse have had to be quarantined.

"Danedream is in perfect health, cantering well and eating well, and is not involved at all in this, but we must abide by the decision of the German authorities," he continued. "In my opinion her prospects of traveling are only very small, but we are awaiting official news from the authorities
