Colonization of a voice prosthesis by Cryptococcus neoformans

Tracheoesophageal voice prostheses in laryngectomized patients commonly deteriorate due to the presence of yeasts, particularly Candidaspecies. We describe the first case of colonization of such a device by Cryptococcus neoformansin a patient with a history of glottic carcinoma. The isolate showed an identical genomic pattern with C. neoformansfrom pigeon excreta in the patient's environment.
