is a well-known cause of fatal pneumonia in some birds, particularly Old World psittacines. Here we describe fatal sarcosystosis due to in 3 penguins (Family Spheniscidae) under managed care, including one African penguin (), and two Southern rockhopper penguins (). Randomly distributed foci of necrosis, inflammatory cell infiltrates, edema, and variable numbers of round to elongated protozoal schizonts were observed in sections of lung. Protozoal organisms exhibited strong immunoreactivity for sp. antigen by immunohistochemistry. Apicomplexan and genus-specific PCR assays and sequence analysis confirmed as the etiologic agent. These cases of fatal pneumonia attributed to expand the list of aberrant intermediate avian hosts, with particular implications for penguins.
是某些鸟类，特别是旧大陆鹦鹉中致命性肺炎的一个众所周知的病因。在此我们描述了3只圈养企鹅（企鹅科）因感染导致的致命性肉孢子虫病，其中包括1只非洲企鹅（）和2只南跳岩企鹅（）。在肺组织切片中观察到随机分布的坏死灶、炎性细胞浸润、水肿以及数量不等的圆形至细长形原生动物裂殖体。通过免疫组织化学检测，原生动物对肉孢子虫属抗原表现出强烈的免疫反应性。顶复门和肉孢子虫属特异性PCR检测及序列分析证实为病原体。这些归因于的致命性肺炎病例扩大了异常中间禽类宿主的范围，对企鹅具有特别的意义。
