During a routine health inspection of apparently healthy wild-caught common mudpuppies Necturus maculosus, the bacteria Yersinia ruckeri was isolated and the identity confirmed using biochemical and molecular methods. This represents the first isolation of Y. ruckeri from an amphibian. This finding increases the known host range capable of harboring this important fish pathogen and could have serious management implications for aquaculture. Furthermore, addressing wild amphibians in fish hatchery biosecurity plans is discussed.

从普通 Mudpuppy Necturus maculosus 中分离出的鲁氏耶尔森菌

在对表面健康的野生捕捞的普通泥巴狗 Necturus maculosus 进行例行健康检查时，分离出鲁氏耶尔森氏菌，并使用生化和分子方法确认了其身份。这是首次从两栖动物中分离出鲁氏耶氏酵母。这一发现增加了能够容纳这种重要鱼类病原体的已知宿主范围，并可能对水产养殖产生严重的管理影响。此外，还讨论了在鱼类孵化场生物安全计划中解决野生两栖动物的问题。
