Batrachochytrium salamandrivorans (Bsal), a pathogenic fungus causing the fatal disease chytridiomycosis in amphibians, was likely introduced to Europe through the trade in pet salamanders from Asia and then escaped into wild populations. Among European countries, Spain has a large number of private breeders and keepers of pet salamanders, and cases of Bsal in wild and captive populations already have been confirmed there. However, surveillance for the pathogen in Spanish collections of amphibians is sparse. Therefore, assisted by private owners and breeders, we surveyed 10 amphibian collections and analysed a total of 317 samples for presence of Bsal. All of our analyses yielded negative results. However, this apparent lack of Bsal cases in captivity should not encourage relaxation of vigilance, quarantine efforts or good practices. Because amphibian collections represent highly dynamic environments (animals are coming in and out), the pathogen could easily be introduced into a collection by new individuals. Any case of Bsal infection in captive animals could lead to its further spread to wild populations of susceptible species, potentially decimating them, and thus should be prevented.
蛙壶菌(Batrachochytrium salamandrivorans,简称Bsal)是一种可导致两栖动物患上致命疾病——壶菌病的致病真菌,它很可能是通过从亚洲进口宠物蝾螈的贸易活动传入欧洲,随后传播至野生种群。在欧洲国家中,西班牙有大量宠物蝾螈的私人饲养者,该国已证实野生和圈养种群中存在Bsal病例。然而,西班牙两栖动物养殖场对该病原体的监测工作十分匮乏。因此,在私人饲养者的协助下,我们对10个两栖动物养殖场进行了调查,并总共分析了317个样本,以检测是否存在Bsal。我们所有的分析结果均为阴性。然而,圈养环境中看似没有Bsal病例这一情况,不应促使人们放松警惕、放松检疫措施或忽视良好做法。由于两栖动物养殖场的环境变化频繁(动物不断进出),新引入的个体很容易将病原体带入养殖场。圈养动物中任何一例Bsal感染都可能导致其进一步传播至易感物种的野生种群,有可能使其数量大幅减少,因此必须加以预防。
