Nannizziopsis guarroi, also known as “yellow fungus”. This fungal infection feeds on reptile skin's keratin and is most commonly seen in anoles, bearded dragons, green iguanas, and water dragons.
Patients with this condition present with one or more yellow to brown areas of discoloration of the skin, thickened skin, crusts, and weight loss.
Diagnosis of Yellow Fungus Disease is made by positively identifying the fungus through a DNA probe called PCR or skin biopsy. Your veterinarian may also recommend additional testing to determine the overall health of your pet including a complete blood count and serum biochemistry panel.
Yellow Fungus Disease is treated with at least 9 weeks of prescription antifungal medications. Antibiotics both topical and systemic may also be prescribed if there is evidence of secondary bacterial infection. This fungus is highly contagious. Any individuals exposed should be monitored for the development of signs.
The prognosis of this condition is guarded to poor. Advanced disease does not always respond well to antifungal therapy and it is important to start treatment early. Those with advanced disease often die within a year despite aggressive medical treatment due to the spread of the fungus deeper into internal organs.
Recheck appointment recommendations are dependent of severity of disease at time of diagnosis.
