摘要

2020年和2021年，我们在加泰罗尼亚（西班牙东北部）检测到引入的地中海彩绘蛙（Discoglossus pictus）出现了六次新的死亡或死亡标本。所有受影响的个体均对两栖动物壶菌Batrachochytrium dendrobatidis（Bd）呈阳性。组织学检查显示表皮浅层严重受累，qPCR分析显示感染量大于100 000个基因组当量的游动孢子。这些结果表明，这种引入的物种可能表现为Bd的“超级hedder”，并建议控制其扩张，因为它在壶菌病的动态中起着重要作用。

Introduced Mediterranean painted frogs (Discoglossus pictus) are possible supershedders of the fungus Batrachochytrium dendrobatidis in Catalonia (NE Spain)

In 2020 and 2021 we detected in Catalonia (NE Spain) six new episodes of mortality or presence of dying specimens in introduced Mediterranean painted frogs (Discoglossus pictus). All affected individuals were positive to the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd). Histological examinations showed intense involvement of the superficial layers of the epidermis and qPCR analyses yielded infection loads greater than 100 000 genomic equivalents of zoospores. These results suggest that this introduced species could behave as a Bd ‘supershedder’, and recommend to control its expansion due to its important role in the dynamic of chytridiomycosis.
