Cutaneous lesions due to Trichosporon jirovecii in a tortoise (Testudo hermanni)

Cutaneous mycoses have been rarely reported in Chelonians. A Testudo hermanni adult male showed a thick erosion of the dorsal neck covered by necrotic material. Trichosporon sp. was cultivated, while arthrospores and hyphae were observed in histological sections. The causative agent was identified as Trichosporon jirovecii by PCR. After a surgical intervention povidone iodine and Iruxol® ointment were daily administered through the drainage for 2 weeks, along with enrofloxacin 5 mg diluted in saline 0.5 ml via the intracelomatic route. After treatment the ulcer healed with residual scars. No relapse was registered after 12 months. T. jirovecii is considered as a rare yeast pathogen and the presented case is the first report of a dermatomycosis in tortoises caused by this yeast species.
