ABSTRACT
A captive black rhinoceros (Diceros bicornis) with a hoof abscess was treated with long-term antibiotic therapy. After 9 months of treatment, there was rapid deterioration, marked weight loss and reluctance to stand. Profuse, bilateral epistaxis developed accompanied by collapse and the animal was euthanased. Necropsy revealed pulmonary aspergillosis with concurrent Pseudomonas aeruginosa infection. Though a well-recognized disease of black rhinoceros, fungal pneumonia has not been reported in this species in Australia. The cost and efficacy of treatment have been questioned, however, prophylactic antifungal drug administration will be considered in any further cases of chronic, debilitating illness in black rhinoceros at Western Plains Zoo.
