A wild South American grey fox found near Santiago, Chile was treated for a skin infection caused by a fungus called Nannizzia gypsea. This is the first time this particular fungus has been documented in foxes, raising concerns about how increasing contact between domestic animals, wildlife, and humans due to urbanization may spread fungal diseases. The fox was successfully treated with topical antifungal cream, and the fungus was found to be susceptible to all tested antifungal medications.
