It is particularly devastating to bearded dragons, often being fatal. Yellow fungus disease is fairly well documented now in several species of reptiles. Over this time, the causative agent has undergone several name changes as microbiologists’ study deeper into the disease. These infections are becoming more common over the last several years, originally identified in North America, then into Europe, and now as far reaching as Australia. Note that although the causative agent was believed to be Chrysosporium anamorph of Nannizziopsis vriesii (CANV), it may be shifting towards N guarroi.ĬANV belongs to a group of fungi which are keratinophilic – meaning that it likes to grow on keratin (the stuff that scales are made of). The name yellow fungus disease comes from the yellow – brown discoloration of infected skin.
