My horse developed a very aggressive infection on his coronary band and the bulb's of his back hooves. This happened after a bout with EPM. He had mud rot for several years which the Vet treated aggressively. But after he went off the Marquis medication it developed in to a much worse infection. After a culture showed he had Pseudomonas aeruginosa and secondary infection of Acinetobacter baumanii. The sensitivity panel showed the only antibiotics that would maybe help would be Amikacin,Geocillim and Ticaracillin. But the Vet said he was not in favor of giving him these for he felt it would tear his stomach up.
I have tried everything and anything any Vet told me, it would get better to a point, and would not continue getting any better. No matter how much longer we tried the medications. Do you have anything to advise me of. I was advised to put him down but he is perfect in every other way. He is starting to stomp the hind left foot violently and swing his head all over and fret. By the way it is only in the hind feet has never gone to the front in 6 years.

Neither the amikacin or the ticarcillin are given orally and neither would have any effect on the stomach at all. The idea that one would put a horse down without trying a antibiotic that has known efficacy for a specific problem is perplexing to me even if toxicity is a possibility as it is with any drug. For more on amikacin in particular see, Equine Medications and Nutriceuticals » Antibiotics and Antimicrobials » Amikacin.
Do you know how deep the infection goes and what structures are involved? Would you tell us what you have done specifically detailing dosage, concentration, frequency, and length of treatment?

He was given Iodine injections in 2000. Since then we have tried Desitin, Teatree,desiex, microtek,Betadine, wonderdust, furacine,Lotriman,tinactin,powders and creme.Fungacide,calamin lotion, panalog-animax creme, Tricare,SMZ( which helped for a while.The last(Nov 2004) thing he was put on was Nolvasan mixed with Metronidazole for 3 days then on Dermagen for 2 days we rotated this treatmentr for 6-7 mo. with daily washing with Nolvasan wound wash, I would blow the feet dry with a blow dryer before putting the med's on.This worked the best but then it came to stand still and would not get any better. So we tried Xxterra this did eat away a lot of the protruding flesh, put while I was doing this the last month the coronary band started to grow a protruding finger like flesh thru the hair(which made it hard to shave the hair). Those fingers are at least 1 inch up the band right now. I rode him the other day and my instructor discribed his way of moving as this. His foot pattern was a scissoring from right to left from right hind leg. Left hind is short strided. This is the one he pounds(very hard on the toe) in his stall when standing. He is becoming fretful and has a lot of anxiety when I take him away from his stall or the other horses. He throws his head violently from one side to the other, even when he is cross tied.
These pictures are from Nov. I will take more right now and email them to you.
I could upload the pictures but the site would not take the data. Is there another site I could scan the files too?
Thank You

My first suggestion Hilma is to quit using caustic materials on this injury. What will keep it from being able to heal is permanent damage to the healthy tissue and caustic substances, like Xxterra, risk this possibility. If you do have proud flesh forming it should be surgically excised.
Until we get this figured out, and with the approval of your veterinarian, I would return to the chlorhexidine, applied twice daily as a 1% solution with a spray bottle and keeping this area absolutely clean and dry. Be sure that your files are less than 64k and you should be able to upload just about any type file. Check the size and try uploading one per message.

Dr O
What I am afraid of at this point is that there is damage to the nerves in the left hind. I have not had a nerve block done yet,I thought it might be the time to have that done.
I still can't send the papers I scanned The attachments are still being removed from my post.
Thank You again for the advise

I would not do nerve blocks in this area Hilma, at least not until the disease is eradicated because if it is infection you might drive it deep into the tissues. What is the format and file size of your documents?
