Título

Bat fungus diversity in the Lower Amazon, Brazil - a describing analysis

Introdução

The Brazilian Amazon biome covers more than 40% of Brazil's territory and is an important centre of biodiversity in the world. Recently, bats have gained prominence due to the emergence of the SARS-CoV-2 pandemic. Human interference has led to increased contact between bats and human populations. Bats adapt easily to peri-urban and urban areas where they can find shelter and food. However, they bring wild and unusual microbiota into these areas. These closely related mammals have been a concern for environmental health surveillance over the years, as they can transmit diseases of public health concern

Objetivo (s)

The aim of our work is to study the fungal diversity in the Amazonian biota through isolates from the gut of chiropterans, Santarém region, Pará, Brazil.

Material e Métodos

Isolation and identification of fungi classical mycology. And molecular characterization of the 5.8S rDNA-ITS region, and SANGER sequencing

Resultados e Conclusão

Were collected 52 bat specimens from two families, Molossidae and Phyllostomidae. Being, 10 bats were collected in urban regions (Caranazal), and 42 bats in peri-urban (UFOPA).Twenty-five filamentous fungi and three yeast fungi were isolated from the urban region. From the peri-urban region, 89 filamentous fungi and seven yeasts were isolated. 70% of both regions contained Penicillium sp. The fungi Paecilomyces sp, Purpureocilium sp, Fusarium sp, Tricoderma and Aspergilus were more common in the urban region. The fungi of the order Mucorales were found more frequently in peri-urban areas. Conclusion: We concluded that we found a fungal mycobiota with greater diversity in urban areas compared to peri-urban areas. We also identified fungi of medical interest such as Penicilum lilacinum. Kokurewicz et al. showed that the concentration of fungi is associated with the number of bats, suggesting that airborne fungi from bats are a potential threat to public health. We emphasise that this is a pioneering study in chiropteran fungal research and studies such as this are extremely important for understanding disease transmission cycles between mammals and humans.
