The rowi is a critically endangered species of kiwi. Young birds on a crèche island showed loss of feathers from the ventral abdomen and a scurfy dermatitis of the abdominal skin and vent margin. Histology of skin biopsies identified cutaneous larval migrans, which was shown by molecular sequencing to be possibly from a species of Trichostrongylus as a cause of ventral dermatitis and occasional ulcerative vent dermatitis. The predisposing factors that led to this disease are suspected to be the novel exposure of the rowi to parasites from seabirds or marine mammals due to the island crèche and the limited management of roost boxes. This is the first instance of cutaneous larval migrans to be recorded in birds. Severe and fatal complications of the investigation resulted in the death of eight birds of aspergillosis and pulmonary complications associated with the use of bark as a substrate in hospital. Another bird died of renal failure during the period of hospitalisation despite oral and intravenous fluid therapy. The initiating cause of the renal failure was not determined. These complications have the potential to undermine the working relationship between wildlife veterinarians and conservation managers. This case highlights that intensive conservation management can result in increased opportunities for novel routes of cross-species pathogen transmission.
罗威几维鸟是一种极度濒危的几维鸟物种。在一个育雏岛上的幼鸟出现了腹部腹侧羽毛脱落以及腹部皮肤和泄殖腔边缘的鳞屑性皮炎。皮肤活检的组织学检查确定为皮肤幼虫移行症，分子测序显示可能由一种毛圆线虫引起，是腹侧皮炎和偶尔的溃疡性泄殖腔皮炎的病因。导致这种疾病的诱发因素被怀疑是由于岛上育雏以及对栖息箱管理有限，罗威几维鸟首次接触到来自海鸟或海洋哺乳动物的寄生虫。这是鸟类中首次记录到皮肤幼虫移行症。调查中的严重和致命并发症导致八只鸟死于曲霉病以及与在医院使用树皮作为基质相关的肺部并发症。另一只鸟在住院期间尽管接受了口服和静脉补液治疗仍死于肾衰竭。肾衰竭的起始原因未确定。这些并发症有可能破坏野生动物兽医和保护管理人员之间的工作关系。这个案例凸显出强化保护管理可能会增加跨物种病原体传播新途径的机会。
