病原体很少导致宿主物种的灭绝，并且很少有病原体通过引起广泛物种的局部灭绝来改变生态群落物种丰富度和多样性的例子。我们报告了在巴拿马El Cope的一个两栖动物群落中，一种致病性壶菌Batrachochytrium dendroatidis的迅速出现与随后青蛙和蝾螈8科两栖动物的大量死亡和生物多样性丧失之间的联系。我们描述了巴拿马壶菌病的爆发，并认为这种传染病在两栖动物种群下降中发挥了重要作用。这种新发传染病的高毒力和大量潜在宿主威胁着全球两栖动物的多样性。
Pathogens rarely cause extinctions of host species, and there are few examples of a pathogen changing species richness and diversity of an ecological community by causing local extinctions across a wide range of species. We report the link between the rapid appearance of a pathogenic chytrid fungus Batrachochytrium dendrobatidis in an amphibian community at El Cope, Panama, and subsequent mass mortality and loss of amphibian biodiversity across eight families of frogs and salamanders. We describe an outbreak of chytridiomycosis in Panama and argue that this infectious disease has played an important role in amphibian population declines. The high virulence and large number of potential hosts of this emerging infectious disease threaten global amphibian diversity.
