| Resumo | |
The chytrid fungus Batrachochytrium dendrobatidis (Bd) poses a serious threat to amphibians worldwide, with its emergence linked to population declines across numerous species. Thus, detecting Bd infection and understanding the patterns within different hosts are essential for evaluating risks, particularly for endemic and threatened species. Therefore, we reviewed and provided novel information on Bd infections in endangered Brazilian amphibians, focusing on three island-endemic species. Additionally, we analyzed Bd occurrence data from studies conducted in the past 20 years on threatened Brazilian amphibians and supplemented these findings with additional records from museum specimens. Our results indicate that Bd is widespread among Brazil's threatened amphibian species but exhibits varied infection patterns. Among the threatened island species, while Cycloramphus faustoi and Ololygon alcatraz exhibited no detectable infections in our fresh samples, Ololygon faivovichi showed high prevalence and infection loads. The detection of Bd in endemic species, particularly in vulnerable island populations with restricted distribution, highlights the urgent need for continued monitoring and proactive conservation actions. These findings are critical for informing the development of long-term management strategies that integrate Bd detection, treatment, and eradication into conservation planning to safeguard Brazil's endangered amphibians and ecosystems.
