Bilateral aural hyalohyphomycosis in sable antelope (Hippotragus niger)

Three juvenile sable antelope (Hippotragus niger) were diagnosed with bilat eral aural hyalohyphomycosis based on histopathology. All three animals wer e suspected to be immunodeficient based on low IgG levels determined using the zinc sulfate turbidity test. The serum and hepatic copper levels of one animal were below the bovine reference range. Clinical signs in the three animals included bilateral ventral deviation of the pinnae with multifocal subcutaneous aural tumefaction and poor body condition. Numerous septate, n onpigmented fungal hyphae were found within the auricular cartilage, dermis , and subcutaneous granulomas. No significant fungal agents were isolated b y culture, and no signs of systemic fungal dissemination were identified ex cept for a concurrent fungal rhinitis in one animal.
