Cutaneous geotrichosis in the red flamingo (Phoenicopterus ruber)

In three flamingos (Phoenicopterus ruber), which died showing extensive necrotic inflammation of the skin of the webs and the legs, the presence of abundant mycelium and arthrospores was shown in the altered dermis and epidermis. From all the lesions Geotrichum Candidum was isolated in pure culture. Inoculation of suspensions of the fungus into domestic chickens and mice produced granulomas or more purulent nodules with central growth of abundant mycelium. From 20 of 28 experimental animals, G. candidum was reisolated from the lesions in pure culture 2 weeks after the inoculation. It is suggested that alteration of the skin by e.g., prolonged contact with pondwater, the presence of small wounds and the advanced age of the birds, acting as predisposing factors may be necessary in establishing this disease.
