Sir Gino’s condition remains stable as he continues to be treated by specialists at Donnington Grove Equine Hospital.
Nicky Henderson described the issue as a “superbug” which has compromised his recovery from what initially seemed a small setback.
Other horses struck down by something similar have not always made a full recovery, so Henderson is hoping his recuperation continues to go in the right direction.
“He’s still in the clinic and he’ll be there for another week anyway. I think they’re hoping that if he stays the same for another week, we might be starting to come out of the woods, but he’s got a way to go yet,” said Henderson.
“The signs are positive because he’s stable and he is where he is. He’s very happy and he’s in no pain or anything, but they’ve got to get this sort of superbug under control.
“It’s bizarre and very, very rare, but it can be very dangerous. I think I’ve seen one with a similar thing before, but a lot of people say they’ve had such and such a horse five years ago and the outcome wasn’t always OK.”
