Plain-English summary
A goat was diagnosed with a rare infection called protothecosis caused by Prototheca wickerhamii, which led to severe breathing problems and painful nodules on its face and nostrils. Despite treatment with fluconazole, the infection did not improve, and the goat was euthanized ten months later due to the progression of the disease. This condition can affect healthy goats and is characterized by chronic, ulcerative lesions. Unfortunately, the infection was resistant to common antimicrobial treatments, making it difficult to manage.

Abstract
This article reports a new case of protothecosis by Prototheca wickerhamii in goats. The animal presented severe respiratory difficulty and nodules, sometimes ulcerated, in the nasal vestibule, mucocutaneous junction of the nostrils and skin of the face. Prototheca wickerhamii was isolated from the lesions. The animal had no clinical or haematologiccl evidence of immunodepression. The agent was highly resistant to antimicrobial drugs. The goat was treated unsuccessfully with fluconazole and euthanised 10 months after the diagnosis of the disease. Histological lesions were necrotising pyogranulomatous dermatitis, rhinitis and osteomyelitis with myriads of walled sporangia characteristic of P. wickerhamii. It is suggested that in goats, protothecosis is characterised by a chronic, slowly progressive infection, which affects immunologically competent goats, causing multifocal, ulcerative, pyogranulomatous and necrotising lesions of the mucosa of the nasal vestibule, mucocutaneous junctions of the nostrils and skin of the face.
