Abstract

Little is known about the prevalence or identity of Sarcocystis species infecting armadillos in North America. Sarcocysts were observed in the tongues of 23 (96%) of 24 armadillos collected between 1989 and 1994 from Texas, Oklahoma, Kansas, and Arkansas. The identity of the species present was determined in histological sections of tongue from armadillos. Sarcocystis dasypi was present in 21 (88%) and Sarcocystis diminuta was present in 5 (21%). Mixed infections with S. dasypi and S. diminuta were present in 3 (13%) armadillos. A single sarcocyst with ultrastructural features distinct from S. dasypi and S. diminuta was observed with transmission electron microscopy.

摘要

关于感染北美洲犰狳的肉孢子虫种类的流行情况或种类特征，人们知之甚少。在1989年至1994年间从得克萨斯州、俄克拉何马州、堪萨斯州和阿肯色州采集的24只犰狳中，有23只（96%）的舌头中观察到了肉孢子囊。通过犰狳舌头的组织切片确定了所存在的肉孢子虫种类。21只（88%）犰狳体内存在达氏肉孢子虫，5只（21%）体内存在微小肉孢子虫。3只（13%）犰狳同时感染了达氏肉孢子虫和微小肉孢子虫。通过透射电子显微镜观察到一个具有与达氏肉孢子虫和微小肉孢子虫不同超微结构特征的单个肉孢子囊。
