In seven calves we studied experimental invasions by sporocysts of the Sarcocystis cruzi (S. bovicanis) species, isolated from faeces of dingo dogs. Out of clinical changes, an increase in body temperature to 39.6 to 40.5 degrees C is characteristic in the fourth to the eighth week of disease, relaxed attitude of animals, progressive thinning down, anaemia of mucous membranes, diarrhoea and total dehydration. The post-mortem examination completes this observation with generalized hyperplasia of lymphatic nodes to haemorrhagic lymphadenitis and small petechial haematomata on serous coats, particularly on epicardium. Schizonts in the endothelium of capillaries in various organs were evaluated as specific lesions, demonstrated within 26 days from invasion in one calf. From 46 days after invasion we found muscular cysts in three other calves. The titres of sera in all experimental calves obtained with the NFR method are also evaluated as specific. Invaded calves died gradually between the 26th and 59th day, control calves were slaughtered and no sarcocysts were found.
我们对7头小牛进行了研究，以观察从澳洲野狗粪便中分离出的克氏肉孢子虫（牛肉孢子虫）孢子囊的实验性侵袭情况。在临床变化方面，疾病的第四至八周，体温升高至39.6到40.5摄氏度是其特征，动物态度松弛、逐渐消瘦、黏膜贫血、腹泻并出现全身脱水。尸检显示淋巴结普遍增生至出血性淋巴结炎，浆膜层，尤其是心外膜出现小的瘀点性血肿，完善了这一观察结果。各器官毛细血管内皮中的裂殖体被视为特异性病变，在一头小牛侵袭后26天内得以证实。侵袭后46天，我们在另外三头小牛中发现了肌肉囊肿。用NFR方法测得的所有实验小牛血清滴度也被视为具有特异性。受侵袭的小牛在第26天至59天之间逐渐死亡，对照小牛被宰杀，未发现肉孢子囊。
