Rhinosporidiosis is a mucocutaneous zooanthroponotic disease caused by Rhinosporidium seeberi, a fungal-like organism of uncertain classification with an unknown mode of transmission. Over a 3 year period, 41 captive swans (Cygnus olor and C. atratus) developed conjunctival and cutaneous polypoid lesions diagnosed as rhinosporidiosis by histopathological examination including light and electron microscopy. Investigation of this avian outbreak, the first of its kind, provides additional insight into the epidemiology of this enigmatic aetiologic agent, which has yet to be isolated and cultivated in vitro. The occurrence of rhinosporidiosis in swans supports an aquatic environment as the reservoir for R. seeberi, which is often associated with exposure to water. We report the first known occurrence of rhinosporidiosis in 41 captive mute (C. olor) and Australian black (C. atratus) swans dwelling on a lake in a Central Florida city. Additionally, we review the development stages of R. seeberi and propose a revision in its ontogenic nomenclature to reflect its probable taxonomic classification as a member of the kingdom Fungi.
鼻孢子虫病是一种皮肤黏膜人畜共患病，由西伯鼻孢子菌引起，西伯鼻孢子菌是一种分类不确定、传播方式不明的类真菌生物。在3年时间里，41只圈养天鹅（疣鼻天鹅和黑天鹅）出现结膜和皮肤息肉样病变，经组织病理学检查（包括光学显微镜和电子显微镜检查）诊断为鼻孢子虫病。对此次首例禽类疫情的调查，为这种神秘病原体的流行病学提供了更多见解，该病原体尚未在体外分离和培养。天鹅中鼻孢子虫病的发生支持了水生环境是西伯鼻孢子菌的储存宿主，这通常与接触水有关。我们报告了佛罗里达州中部一个城市的湖泊中41只圈养疣鼻天鹅（疣鼻天鹅）和澳大利亚黑天鹅（黑天鹅）首次出现鼻孢子虫病。此外，我们回顾了西伯鼻孢子菌的发育阶段，并提议对其个体发育命名法进行修订，以反映其可能作为真菌界成员的分类地位。
