Paracoccidioidomycosis (South American blastomycosis) in a squirrel monkey (Saimiri sciureus)

A female squirrel monkey (Saimiri sciureus) had granulomatous lesions in the liver and colon. There were many fungal organisms in sections of liver and many of these organisms had multiple buds on their surface. Although we did not prepare fungal cultures, the appearance of the organisms was sufficient to identify them as Paracoccidiodes brasiliensis, the cause of paracoccidioidomycosis (South American blastomycosis).
