Both captive and free-living reptiles are susceptible to infection by fungi from the Nannizziopsis genus and are prone to developing severe lesions that can affect skin and deeper tissues, becoming multi-systemic. With Australia having close to 1000 reptile species—of which 93% are endemic—the prevalence, distribution and susceptibility of reptiles to this emerging fungal infection remain unknown. In this case series, captive skinks originating from the states of Queensland and Western Australia were presented to wildlife veterinarians with dermatitis. Nannizziopsis pluriseptata was identified via fungal isolation, PCR (polymerase chain reaction) and sequencing, confirming the first record of this pathogen in the country.
