Mysterious Wounds, Vet has NO CLUE

Hello everyone,

My new horse Mozart had a leg injury on his right hind leg back in July that wasn't healing, it was really ugly and we were unsure of how he did it. Several weeks later (five to be exact) after seeing no progress in healing, I called the vet out. My vet has been a vet for over 30 years and she has no clue what is wrong with his leg. Furthermore, his front leg is now doing the same thing and has the same kind of wound on it. The flesh, litteraly, falls off of both his legs on the right side. Its ugly, its sore, and its not going away. The vet will be out tomorrow to do a culture and also a biopsy of the flesh to see if we can figure out what is wrong. Below are pictures of his legs. They are nasty looking! I just thought I'd share to see if maybe anyone has seen anything like this before.

The vet had him on Antibiotics and they were getting better, then I ran out and the vet said he shouldn't need anymore, and the wounds got worse again, so the vet stopped by and dropped off more antibiotics and he is on them now. So far, his legs are still not getting better. I am so tired of this battle with whatever it is and I'm hoping the tests we do tomorrow will shed some light on the subject matter and tell me what it is so I can fix it properly.

This is his back leg, which for a while there, looked better. But now its back to worse. Also the lump on the skin is soft and squshy like there is fluid in it, the vet has yet to see that lump so it will be discused tomorrow.

This is the front of his right front leg, this just started to open up, which is why it doesn't look as bad.

And this is the back of his right front leg.

It is almost like his flesh is rotting off. There is no pus or anything like that, his skin just falls off when you touch his legs. It is also not contagious. His front leg is not infected due to contact with his back leg or anything like that. If anyone has seen anything like this before please help! I am so sick of this I could scream.

I'm no vet, but it looks almost like pemphigus foliaceus or another auto-immune disease. It can appear in different species, my experience comes from treating a cat who had almost similar sores to your horse, although all over her body, not just legs. She was successfully treated with prednisolone, but she's on the drug for the rest of her life now, otherwise the sores return.

I have heard of this condition but never seen one. It sure looks like everything I have read about pemphigus foliaceu. Show this to your Vet.

The culture results came back on Mozart's legs. Its a bacteria called trueperella pyogenes and its a bizarre bacteria that my vet has never heard of before. Even the lab is running further tests to see what exactly causes it. Right now he is on antibiotics and steroid cream applied to the wounds. Seems to be working for now.

Mozart Update

Hello All,

I am giving anyone who might be interested in an update on Mozart and his weird leg problems. We figured out what it is but we are still fighting to make it better. His back leg is healed (finally) and the front of his front leg is healing up nicely as well. However, the back of his front leg looks awefull. He will be starting penicillin on Friday and hopefully that will give him the chance to heal the back of his front leg.

This is what the front of his front leg looks like now:

and this is how the back of his front leg looks. Its actually healing everywhere but that large lump. (he had a similar lump on his hind leg that went away on its own, hopefully this one will too)

That is the craziest thing I have ever seen.

Does the vet know anymore about what this was? Like what caused it? A quick google search said its the same family as Mastitis but that seems far fetched to me given how nasty it has brewed... I would really be interested in knowing more about what caused it.

Very strange indeed! I hope you can get it cleared up.

Does the vet have any idea on how that particular bacteria travels from animal to animal? (As in, where did it come from?)

I'd certainly be keeping him in a strict quarantine. We don't want any of your other horse's getting it.
