Abstract

A 5-year-old male neutered rabbit was presented for assessment of multiple abscesses, which had appeared suddenly over the ventrum, perineum and hindlimbs over the previous few days. Thirteen abscesses were surgically excised. Culture revealed Pseudomonas aeruginosa and histopathological examination confirmed a diagnosis of botryomycosis. However, despite follow up antimicrobial treatment and repeat surgeries, lesions continued to recur. The second case, a 3-year-old male neutered rabbit presented for routine vaccination. On physical examination, multiple small nodules were palpated over the right shoulder region. Surgical excision was performed and histopathology again yielded a diagnosis of botryomycosis. So far, no recurrence has been seen in this case. Botryomycosis is a rare chronic pyogranulomatous infection and naturally occurring disease has not been previously reported in pet rabbits. These cases highlight the challenges of treatment and the importance of prompt diagnosis.
