The liver of a fox squirrel (Sciurus niger rufiventer) contained many clear, spherical cysts approximately 1 mm in diameter throughout the parenchyma. On dissection, most of these exhibited a dense, white area with four muscular suckers at a single point on the bladder. Based on the size of the organisms, the characteristically tiny hooks on the scolex and the location of the cysts in this host, the parasites were identified as cysticerci of Taenia mustelae. This is the first report in this host. The parasites were surrounded by an intense inflammatory response consisting primarily of lymphocytes mixed with some eosinophils, and early deposition of fibrous connective tissue.
一只狐松鼠（Sciurus niger rufiventer）的肝脏实质内布满了许多直径约1毫米的透明球形囊肿。解剖时，大多数囊肿呈现出一个致密的白色区域，在囊泡的单个点上有四个肌肉吸盘。根据生物体的大小、头节上典型的微小钩以及这些寄生虫在宿主体内的位置，确定这些寄生虫为鼬绦虫的囊尾蚴。这是该宿主中的首次报告。寄生虫周围有强烈的炎症反应，主要由淋巴细胞混合一些嗜酸性粒细胞组成，并有纤维结缔组织的早期沉积。
