Plain-English summary

A dog with chronic ear infections that weren't responding to antibiotics was diagnosed with a fungal ear infection caused by Aspergillus. The dog had a lot of inflammation and pus in the ear, and tests showed the presence of the fungus. Treatment included allergy shots, antifungal medications, and steroids to reduce inflammation. The dog's condition improved significantly after cleaning the ear and using a topical antifungal called ketoconazole, along with addressing the underlying allergies.

Abstract

AbstractThis report describes the clinical findings, clinicopathology and treatment of otomycosis caused by Aspergillus spp. in an atopic dog affected by chronic unilateral purulent otitis externa unresponsive to topical and oral antibiotics and antifungal treatments. Cytology of otic exudate revealed neutrophils and septate fungal hyphae, and otic culture grew Aspergillus spp. and no bacteria. Treatments included allergen‐specific immunotherapy, topical and oral antifungal therapy and anti‐inflammatory steroid therapy. Final resolution occurred after treatment of the underlying hypersensitivity disorder, administration of topical ketoconazole and debridement of infectious ear exudate. Otomycosis due to filamentous fungi may, as in humans, occur in dogs with ear canals compromised by pre‐existing allergic or bacterial otitis, and possibly previous antibiotic therapy. Antifungal medications provided clinical improvement, but the key to successful treatment was the restoration of the normal physiology of the external auditory canal.
