We evaluated the mortality due to aspergillosis in free-ranging Magellanic penguins during their migration and the reproductive season. A total of 98 carcasses of penguins were collected along 370 km of coastline in Southern Brazil, between June 2017 and October 2019, and from reproductive colonies in Patagonian Argentina, in January 2019. All animals were necropsied, and only proven cases were computed. Aspergillosis was diagnosed in 2.5% of the penguins evaluated during their migration route. Our study, of the Southern coast of Brazil, is the first to demonstrate that aspergillosis is an important cause of mortality in free-ranging penguins. The implications of these findings in the One Health context are discussed.
我们评估了在麦哲伦企鹅迁徙和繁殖季节期间，自由放养的麦哲伦企鹅因曲霉菌病导致的死亡率。在 2017 年 6 月至 2019 年 10 月期间，我们在巴西南部的 370 公里海岸线以及阿根廷巴塔哥尼亚的繁殖地收集了 98 具企鹅尸体。对所有动物进行了剖检，仅计算确诊病例。在迁徙路线上评估的企鹅中，有 2.5%被诊断患有曲霉菌病。我们在巴西南部沿海进行的这项研究首次表明，曲霉菌病是自由放养企鹅死亡的一个重要原因。讨论了这些发现在大健康背景下的意义。
