Infection records of Batrachochytrium dendrobatidis (Bd), a pathogen that has devastated amphibian populations worldwide, have rapidly increased since the pathogen’s discovery. Dealing with so many records makes it difficult to (a) know where, when and in which species infections have been detected, (b) understand how widespread and pervasive Bd is and (c) prioritize study and management areas. We conducted a systematic review of papers and compiled a database with Bd infection records. Our dataset covers 71 amphibian families and 119 countries. The data revealed how widespread and adaptable Bd is, being able to infect over 50% of all tested amphibian species, with over 1000 confirmed host species and being present in 86 countries. The distribution of infected species is uneven among and within countries. Areas where the distributions of many infected species overlap are readily visible; these are regions where Bd likely develops well. Conversely, areas where the distributions of species that tested negative overlap, such as the Atlantic Coast in the USA, suggest the presence of Bd refuges. Finally, we report how the number of tested and infected species has changed through time, and provide a list of oldest detection records per country.

Batrachochytrium dendrobatidis ( Bd ) 是一种在全世界范围内摧毁两栖动物种群的病原体，自病原体发现以来，其感染记录迅速增加。处理如此多的记录使得难以 (a) 知道在何处、何时以及在哪些物种中检测到感染，(b) 了解Bd 的广泛性和普遍性，以及 (c) 优先考虑研究和管理领域。我们对论文进行了系统审查，并编制了一个包含Bd感染记录的数据库。我们的数据集涵盖 71 个两栖动物科和 119 个国家。数据揭示了Bd 的广泛性和适应性是，能够感染超过 50% 的所有测试两栖动物物种，确认宿主物种超过 1000 种，存在于 86 个国家/地区。受感染物种在国家之间和国家内部的分布不均。许多受感染物种的分布重叠的区域很容易看到；这些是Bd可能发展良好的地区。相反，测试阴性的物种分布重叠的地区，例如美国的大西洋海岸，表明存在Bd避难所。最后，我们报告测试和感染物种的数量如何随时间变化，并提供每个国家最古老的检测记录列表。
