salamandrivorans Batrachochytrium salamandrivorans （Bsal）是一种两栖动物的真菌病原体，出现在欧洲，可能通过国际贸易或其他途径传入北美。为评价长尾沙虫入侵对北美10科35种两栖动物生物多样性的影响，对5种两栖动物的幼虫进行了剂量反应试验。我们发现，在被测试的物种中，有74%的物种被Bsal感染，35%的物种死亡。蝾螈和青蛙都被感染并发展为底壶菌病。基于寄主易感性结果、Bsal的环境适宜性条件和美国蝾螈的地理分布范围，预测美国阿巴拉契亚地区和西海岸的生物多样性损失最大。感染和疾病易感性指数表明，北美两栖动物物种跨越了对底壶菌病的易感性谱，大多数两栖动物群落将包括耐药、携带和扩增物种的组合。据预测，美国的蝾螈数量将超过80种，北美的蝾螈数量将超过140种。新出现的真菌病原体Bsal是两栖动物的潜在威胁。在这里，作者使用来自35种两栖动物的剂量反应实验数据来评估北美两栖动物对Bsal的脆弱性，并确定潜在风险的物种和地区。
Batrachochytrium salamandrivorans (Bsal) is a fungal pathogen of amphibians that is emerging in Europe and could be introduced to North America through international trade or other pathways. To evaluate the risk of Bsal invasion to amphibian biodiversity, we performed dose-response experiments on 35 North American species from 10 families, including larvae from five species. We discovered that Bsal caused infection in 74% and mortality in 35% of species tested. Both salamanders and frogs became infected and developed Bsal chytridiomycosis. Based on our host susceptibility results, environmental suitability conditions for Bsal, and geographic ranges of salamanders in the United States, predicted biodiversity loss is expected to be greatest in the Appalachian Region and along the West Coast. Indices of infection and disease susceptibility suggest that North American amphibian species span a spectrum of vulnerability to Bsal chytridiomycosis and most amphibian communities will include an assemblage of resistant, carrier, and amplification species. Predicted salamander losses could exceed 80 species in the United States and 140 species in North America. The emerging fungal pathogen Bsal is a potential threat for amphibians. Here, the authors use data from dose-response experiments on 35 species to assess vulnerability of North American amphibians to Bsal and identify species and areas potentially at risk.
