Nannizziopsis guarroi is an ascomycete fungus associated with necrotizing dermatitis in captive green iguanas and bearded dragons across Europe and North America. Fulfilling Koch's postulates criteria in an experiment demonstrated N. guarroi as the primary agent of yellow fungal disease in bearded dragons. Symptoms include swelling, lesion formation, and progression into crusty, yellow, necrotic scales.
Nannizziopsis guarroi is an ascomycete fungus associated with a necrotizing dermatitis in captive green iguanas (Iguana iguana) and bearded dragons (Pogona vitticeps) across both Europe and North America. Clinical signs of the disease include swelling and lesion formation. Lesions develop from white raised bumps on the skin and progress into crusty, yellow, discolored scales, eventually becoming necrotic. The clinical signs are the basis of a colloquial name yellow fungal disease (YFD). However, until now, N. guarroi has not been confirmed as the primary agent of the disease in bearded dragons. In this experiment, we fulfill Koch's postulates criteria of disease, demonstrating N. guarroi as the primary agent of YFD in bearded dragons.
