HO Reuter, [13 Jun 2022 at 22:28:47]: Good evening, I quite often see and treat abscesses on the jaw of especially nyala (also other species. I have also found and treated Coenurus cysts on the jaw of nyala and sable). Sometimes these jaw abscess caused by gum injury from feed/ lucerne sticks are easy to drain, flush and respond to single long acting antibiotic injections. However, I have sometimes seen typical lumpy jaw bone lesions on lower mandible. What is the most effective, practical and cost effective treatment once bone involvement has occurred in your experiences (Henry and others)? Henry Labuschagne, [14 Jun 2022 at 01:39:59]: Unfortunately in most cases no quick fix or cheap option. It depends on what the cause is and if swelling is from soft tissue or bone and how long before intervention. Also need to rule out tooth root abscess. Ideal to do X ray and take swab for culture and antibiogram. I get best results with Excede s/c , Sodium Iodide iv repeated every 10days for 3 injections. If possible drain abscess and flush with peroxide and tincture of iodine and infuse DC intra mammary antibiotic. If possible post photo. HO Reuter, [14 Jun 2022 at 07:37:24]: This recent case there is soft tissue scar tissue on the side of the jaw, but definitely thickening of mandible to side and bottom as is typical with Actinomyces infection (lumpy jaw). I did not take X-rays or swab. Basically did similar treatment to your recommendation except no Sodium Iodide. What formulation / dosage, and what are the chances of improvement with 3 treatments over a month. I know the bone thickening and lesions are permanent, but is she likely to eat properly and pick up condition (estimated 8-10 year old ewe). I did not take photos, but farmer had sent this photo before treatment. Andreas Gaugler, [14 Jun 2022 at 07:55:43]: SwaVet in Namibia usually stocks Sodium Iodide 50% from Kyron which I use quite a lot in small stock (subcut) and cattle and horse iv HO Reuter, [14 Jun 2022 at 07:57:24]: What dosage do you use? Andreas Gaugler, [14 Jun 2022 at 08:17:44]: I go with label : 2-7 ml per 50 kg iv . Small stock 4 ml subcut. It stings like hell Henry Labuschagne, [14 Jun 2022 at 08:24:06]: I use @ 7ml per 50 kg slow iv. Not in pregnant animals. 3x q 10days. That photo looks like a molar root abscess.
