Abstract

Introduction: Amphibians, a clade crucial for the diversification and evolution of terrestrial vertebrates, currently face significant global threats due to fungal skin infections. However, the interaction between fungi and amphibians is key to host health and the conservation of their ecosystems. Objective: To compare fungal richness and composition across forested, intermediate, and urbanized zones, identifying recurring morphotypes associated with different habitat environments, and analyze their ecological implications for conservation. Methodology: Sampling was conducted over three nights by a team of four biologists, spanning from an urbanized area to a native forest in Bahía Málaga, Buenaventura, Colombia. Individuals were captured for a maximum of one hour, and skin samples were taken using sterilized cotton swabs, placed in Falcon tubes with nutrient medium and antibiotics. Samples were transported at 2–8 °C to the Universidad de Antioquia, where they were cultured on Sauro Agar Petri dishes, monitored daily, and isolated colonies were described. Multiple controls were implemented to verify medium and environmental contamination. Identification was performed using optical microscopy. Results: Representative strains of the genera Fusarium, Penicillium, Phialophora, and Trichosporon were isolated, along with 19 additional culturable filamentous fungal morphotypes. Conclusion: The fungal diversity isolated from C. fitzingeri highlights the ecological role of anurans as important reservoirs of mycobiota in their epidermis. These findings establish a baseline for exploring host-fungus interactions in tropical environments, relevant to amphibian health and conservation studies.
