ABSTRACT: 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.

调查西班牙两栖动物被捕集的Batrachochytrium salamandrivorans的存在

摘要:Batrachochytrium salamandrivoransBsal)是一种致病性真菌,在两栖动物中引起致命的乳糜菌病,很可能是通过亚洲的宠物sal贸易引入欧洲的,然后逃到了野生种群中。在欧洲国家中,西班牙拥有大量的私人sal和宠物sal饲养者,并且已经确认野外和圈养种群中的Bsal病例。但是,对西班牙两栖动物的病原体监测很少。因此,在私人拥有者和育种者的协助下,我们调查了10个两栖动物集合,并分析了总共317个样本中是否存在Bsal。我们所有的分析均得出负面结果。但是,圈养的这种明显缺乏Bsal病例不应鼓励放松警惕,隔离工作或良好做法。由于两栖动物集合代表了高度动态的环境(动物不断进出),因此病原体很容易被新个体引入到集合中。圈养动物中的任何Bsal感染病例都可能导致其进一步传播到易感物种的野生种群中,有可能使它们灭绝,因此应予以预防。
