The reaction of the tissues to an infection with Cysticercus bovis was studied on material from cattle with a spontaneous and an experimental infection. The authors examined a total of 232 cysts from the skeletal muscles. A tissue reaction to C. bovis was inflammatory in nature and originated always at the site at which the invaginated scolex opened into the surface. Typical of these changes were the origin of a pseudoepithelial rim and a zone of granulation tissue maturing on the periphery. At a later phase marking the start of necrotic changes in the cysticercus, the inflammation accompanied by exudation started to develop anew. Calcified structures stirred up a giant cell, cleaning up reaction, and cicatrization followed the resorption of the parasite and the exudate. We identified two types of necroses in a tissue reaction to C. bovis: a focal necrosis of the exudate and the inflammatory rim with a subsequent dystrophic calcification, and a focal necrosis and calcification of collagenous fibres and their groups. Necrotic-like foci typical of a reaction to C. bovis were seen in the inflammatory rim. Using specific staining procedures, we succeeded in distinguishing these foci which did not succumb completely to a dystrophic calcification, from concomitantly present necrotic foci.
利用来自自然感染和实验感染牛的材料，研究了牛囊尾蚴感染后组织的反应。作者共检查了来自骨骼肌的232个囊肿。对牛囊尾蚴的组织反应本质上是炎症性的，总是起源于内陷的头节开口于表面的部位。这些变化的典型特征是假上皮边缘的形成和周边肉芽组织的成熟区域。在囊尾蚴开始出现坏死变化的后期，伴有渗出的炎症开始重新发展。钙化结构引发了巨细胞清理反应，寄生虫和渗出物吸收后随之出现瘢痕形成。我们在对牛囊尾蚴的组织反应中识别出两种坏死类型：渗出物和炎症边缘的局灶性坏死，随后发生营养不良性钙化；以及胶原纤维及其群组的局灶性坏死和钙化。在炎症边缘可见典型的对牛囊尾蚴反应的类坏死灶。通过特定的染色程序，我们成功地将这些未完全发生营养不良性钙化的病灶与同时存在的坏死病灶区分开来。
