Description
Summary:Amazon River dolphins are an important flagship species in the Anavilhanas National Park, Brazil, where they interact with visitors. This study aimed to quantify and identify fungi isolated from dolphin skin and oral samples and their surrounding environment in this unique ecosystem. Samples were collected from three dolphins and water samples from Flutuante dos Botos and the Novo Airão city harbor. Fungi were isolated using culture media and identified through micromorphology assays and ITS region sequencing. Oral swab samples resulted in culture of Trichosporon montevideense and Exophiala dermatitidis. Skin samples from one dolphin revealed Toxicocladosporium irritans and Diaporthe lithocarpus. Water samples exhibited higher fungal counts and diversity, with Rhodotorula mucilaginosa, Exophiala dermatitidis, Penicillium citrinum, Fomitopsis meliae, and Nectria pseudotrichia identified at the collection site and Candida spencermartinsiae and Penicillium chermesinum at the city harbor. This study provides important insights into the fungal diversity associated with Amazon River dolphins and their environment, enhancing our understanding of the public health and ecological dynamics in the Anavilhanas National Park.
