Fusariosis in a Captive South American Sea Lion (Otaria flavescens): A Case Report
- 89 Downloads
Superficial mycoses are commonly reported in captive pinnipeds, usually maintained in wet and warm environments, favorable to fungal growth. Most superficial mycoses in pinnipeds have been described as difficult to treat; however, the majority of the reports come from past decades. Cutaneous lesions associated with opportunistic Fusarium sp. infections have been previously recognized in this taxon. We described the clinical signs, associated lesions and diagnosis (thermography, imprint cytology, histopathology, culture, electron microscopy, PCR) of a fusariosis case by Fusarium sp. in the nails and skin of an adult male captive South American sea lion (Otaria flavescens) recently transferred from another zoological institution, and its successful long-term treatment with Ketoconazole PO (60 days) and Miconazole solution spray TO, followed by Itraconazole PO (30 days). Herein we provide a successful approach to the diagnosis and treatment of fusariosis.
