Meningoencephalitis due to infection with Trichosporon montevideense was diagnosed in a 4-year-old dog with a brief clinical history of rapidly progressing neurological signs that culminated in a comatose state. No significant gross lesions were found at post-mortem examination. Microscopically, a few scattered areas of pyogranulomatous inflammation with a few small, non-pigmented fungal hyphae were found within the cerebrum surrounding the lateral ventricles. A Trichosporon sp. was identified through culture of the brain and species was determined via sequence analysis of the internal transcribed spacer region of the Trichosporon rRNA gene. DNA in-situ hybridization confirmed the diagnosis. This is the first reported case of Trichosporon-associated meningoencephalitis in a dog.
