The chytrid fungus Batrachochytrium dendrobatidis (Bd) has been linked to the declines of more than 500 amphibian species globally. In Brazil, Bd has been identified in several regions but predominantly in the Atlantic Forest. Data on the occurrence of this amphibian pathogen in northeastern Brazil are scarce, specifically from the Caatinga ecoregion, where there is only one study that reports Bd in the region. This study is the first to show a high prevalence of Bd in Caatinga’s species and includes two new records of species infected by Bd: Rhinella granulosa and R. jimi. In addition, we discuss the possibility of amphibian with terrestrial habits serving as potential Bd reservoirs in semiarid climate regions.

巴西 Caatinga 令人担忧的消息：两栖动物中 Batrachochytrium dendrobatidis 的流行

壶菌属 Batrachochytrium dendrobatidis (Bd) 与全球 500 多种两栖动物物种的减少有关。在巴西，已经在几个地区发现了 Bd，但主要是在大西洋森林中。关于这种两栖动物病原体在巴西东北部发生的数据很少，特别是来自卡廷加生态区，那里只有一项研究报告了该地区的 Bd。这项研究首次显示了卡廷加物种中 Bd 的高流行率，并包括两个受 Bd 感染的物种的新记录：颗粒鼻虫和 R. jimi。此外，我们讨论了具有陆地习性的两栖动物作为半干旱气候地区潜在 Bd 库的可能性。
