Infection with Nannizziopsis guarroi and Ophidiomyces ophiodiicola in reptiles in Taiwan.

Fungal infection is an emerging threat to reptiles. The main pathogens are fungi of the genera Nannizziopsis, Paranannizziopsis and Ophidiomyces. The clinical symptoms range from mild skin lesions to the dissemination of internal organs and even death. Most of the reported cases are from Europe, North America and Australia. In this study, we report the Nannizziopsis guarroi infection in one captive inland bearded dragon (Pogona vitticeps), one captive green iguana (Iguana iguana) and Ophidiomyces ophiodiicola infection in one wild red-banded snake (Dinodon rufozonatum) and one wild Chinese cobra (Naja atra) in Taiwan. The infections were confirmed by the presence of fungal elements in the tissue. The pathogens were identified based on their morphological and DNA sequence characteristics. The susceptibility profiles of the fungal strains to nine antifungal drugs were obtained using broth microdilution methods. The presence of both fungal species in Asia highlights the urgent need for surveillance and close monitoring of reptile infections to prevent them from spreading and to the possible collapse of reptile populations in the wild.
