新出现的传染性疾病壶菌病是引发全球两栖动物数量下降的主要因素之一。最近发现的一种壶菌，可能起源于东亚的Batrachochytrium salamandrivorans (Bsal)，在被引入荷兰和比利时后，导致了火蝾螈（Salamandra Salamandra）种群的大规模下降。在这里，我们报告了在德国首次检测到这种病原体，在那里它引起了火蝾螈的大量死亡。从这个收集的蝾螈几乎100%感染了Bsal。在Salamandra、S. algira、S. cors嘉和S. infraimmaculata等多个Salamandra物种中都发生了Bsal引起的死亡，而Salamandra的9个亚种和S. algira中都证实了Bsal感染。我们的研究表明，该病原体可以感染所有火蝾螈种和亚种。如果Bsal从圈养种群传播到野生种群，那么应该会出现与高死亡率相关的类似破坏性影响。
The emerging infectious disease chytridiomycosis is one of the major factors triggering global amphibian declines. A recently discovered species of chytrid fungus, Batrachochytrium salamandrivorans (Bsal), likely originated in East Asia, has led to massive declines in populations of fire salamanders (Salamandra salamandra) after its apparent introduction to the Netherlands and Belgium. Here, we report the first detection of this pathogen in Germany where it caused mass mortality of fire salamanders in a captive collection. Salamanders from this collection showed an almost 100% prevalence of infection with Bsal. Supposed Bsal-induced mortality occurred in multiple Salamandra species (S. salamandra, S. algira, S. corsica, and S. infraimmaculata), while Bsal infection was confirmed in nine subspecies of S. salamandra and in S. algira. Our study indicates that this pathogen can potentially infect all fire salamander species and subspecies. If Bsal spreads from captive collections to wild populations, then a similar devastating effect associated with high mortality should be expected.
