Twelve 30- to 75-day-old mixed breed lambs were examined in an intensive system because of sudden recumbency and death. Clinical examination revealed sudden recumbency, visceral pain, and auscultation of respiratory crackles. Lambs died shortly (between 30 minutes and 3 hours) after the onset of clinical signs. The lambs were necropsied, and after routine parasitology, bacteriology and histopathology procedures, the occurrence of acute cysticercosis caused by Cysticercus tenuicollis was confirmed. The use of the suspect infested feed (newly purchased starter concentrate) was discontinued and other lambs of the flock were treated with praziquantel (15 mg/kg, single dose, orally). After these actions, no new cases were observed. The present study showed the importance of preventive measures against cysticercosis in intensive sheep farming systems which include proper storage of feed, preventing feed and environmental access by potential definitive hosts, and implementing consistent parasite control programs in dogs that are in contact with sheep.
十二只 30 至 75 日龄的杂种羔羊因突然卧地不起和死亡而在强化系统中进行检查。临床检查显示突然卧地不起、内脏疼痛和呼吸爆裂声听诊。羔羊在出现临床症状后不久（30 分钟至 3 小时之间）死亡。对羔羊进行剖检，在进行常规寄生虫学、细菌学和组织病理学程序后，确认发生了由细粒棘球蚴引起的急性囊尾蚴病。停止使用可疑受感染的饲料（新购买的起始浓缩饲料），并用吡喹酮（15mg/kg，单剂量，口服）治疗羊群中的其他羔羊。采取这些措施后，没有观察到新的病例。本研究表明，在集约化绵羊养殖系统中，针对囊尾蚴病的预防措施非常重要，这些措施包括饲料的妥善储存、防止潜在终宿主接触饲料和环境，以及对与绵羊接触的狗实施一致的寄生虫控制计划。
