Plain-English summary

A 13-year-old French saddle gelding horse was brought in for skin problems on the pastern area that had been present for six weeks. After examining skin samples, the vet found a type of small vessel inflammation and identified a resistant bacterial infection caused by Pseudomonas aeruginosa. The horse was treated with a six-week course of enrofloxacin, an antibiotic, and showed significant improvement with no return of the skin lesions.

Abstract

BACKGROUND: Equine pastern vasculitis is an uncommon disorder in horses. Underlying causes are difficult to assess, especially bacterial infections. CLINICAL SUMMARY: A 13-year-old French saddle gelding horse presented for evaluation of a six weeks history of pastern dermatitis. Histopathological examination of skin biopsy samples revealed small vessel vasculitis. A pure growth of a multidrug-resistant Pseudomonas aeruginosa (MRPA) was obtained from a deep skin biopsy. Clinical remission was observed after a six week course of enrofloxacin and lesions did not recur. CONCLUSIONS AND CLINICAL IMPORTANCE: To the best of the authors' knowledge, this is the first report of a pastern vasculitis associated with MRPA and successfully treated with a six week course of enrofloxacin.
