欧洲本地水貂（Mustela lutreola）的数量严重下降。一个负责任的因素可能是由外来的美国水貂（Mustela vison）带来的传染病。为了研究阿留申水貂病细小病毒（ADV）的可能作用，我们调查了本地河岸食肉动物和野生美国水貂。当从12个自由放养的欧洲和16个野生美国貂的血清样本进行了测试，抗体ADV检测从三个9欧洲貂。聚合酶链反应检测ADV DNA的全细胞DNA从7具尸体，两个美国貂，一个欧洲貂和欧亚水獭（Lutra Lutra）。阿留申病的典型病变出现在一只美国水貂身上。对ADV VP2衣壳基因的一部分进行了测序，结果表明，两种序列类型的ADV在西班牙流行，并且西班牙ADV不同于来自北美和欧洲的其他描述的分离株。未来的保护和恢复工作应包括采取措施，以避免引进或传播ADV感染的本地动物。
Serious declines in populations of native European mink (Mustela lutreola) have occurred in Europe. One responsible factor may be infectious diseases introduced by exotic American mink (Mustela vison). In order to investigate a possible role for Aleutian mink disease parovirus (ADV), we surveyed native riparian carnivores and feral American mink. When serum samples from 12 free-ranging European and 16 feral American mink were tested, antibodies to ADV were detected from three of nine European mink. ADV DNA was detected by polymerase chain reaction in whole cell DNA from four of seven carcasses; two American mink, one European mink and a Eurasian otter (Lutra lutra). Lesions typical of Aleutian disease were present in one of the American mink. A portion of the ADV VP2 capsid gene was sequenced and the results suggested that two sequence types of ADV were circulating in Spain, and that the Spanish ADVs differed from other described isolates from North America and Europe. Future conservation and restoration efforts should include measures to avoid introduction or spread of ADV infection to native animals.
