Abstract

Sarcocystis pinnipedi is an apicomplexan protozoal parasite that was first recognized during a mass mortality event in juvenile grey seals (Halichoerus grypus) in the northwest Atlantic Ocean. Since its identification, this parasite has been reported in various pinniped species and has been associated with fatal necrotizing hepatitis. Little is known of the host range of S. pinnipedi. Here we report 2 cases of California sea lions (Zalophus californianus) in managed care that died following an 8-d history of inappetence, vomiting, diarrhea, and progressive lethargy with elevated hepatic enzyme activities. Postmortem examination identified hepatitis and icterus. Sarcocystis schizonts and zoites were identified in regions of necrosis. Molecular and ultrastructural findings demonstrated the close relatedness of this Sarcocystis to S. canis, which produces a similar lesion in bears.

2例加利福尼亚海狮致死性坏死性肝炎的鳍足肌囊虫感染的临床病理、分子和超微结构特征。
鳍足Sarcocystis pinnipedi是一种顶端复合体原生动物寄生虫,在西北大西洋幼海豹(Halichoerus grypus)的大规模死亡事件中首次被发现。自发现以来,这种寄生虫已在各种鳍足动物中报道,并与致命的坏死性肝炎有关。对S. pinnipedi的寄主范围知之甚少。在此,我们报告2例加利福尼亚海狮(Zalophus California)在管理护理中死于8天的食欲不振、呕吐、腹泻和进行性嗜睡伴肝酶活性升高。死后检查发现肝炎和黄疸。在坏死区域发现裂殖体和梭形体。分子和超微结构的研究结果表明,这种肉囊菌与犬链球菌有密切的关系,后者在熊身上产生类似的病变。
