Successful Treatment of <i>Cryptococcus gattii</i> in an Immunocompetent Adult Rhesus Macaque (<i>Macaca mulatta</i>)

An adult female rhesus macaque presented during routine annual physical examination for evaluation of a 2.5-cm diameter superficial ulcerated dermal lesion that was subsequently diagnosed as a systemic fungal infection caused by Cryptococcus gattii. Cryptococcus gattii is one of several basidiomycetic yeasts responsible for pulmonary, neurologic, and disseminated infections in humans and animals.
