Coenurosis is a central nervous system disease of wild and domestic ruminants caused by Coenurus cerebralis, a bladder worm stage of Taenia multiceps). Even in Sardinia island, this metacestode seems to be widespread in sheep (Scala et al. Vet Parasitol 143(3-4):294-298, 2007) where coenurosis is an important health problem (Varcasia et al. Parasitol Res 99(5):622-626, 2006) the last and unique report of coenurosis in cattle was in 1990 (Cubeddu et al. 1990). In the present paper, a case of bovine coenurosis in Sardinia was described 22 years after the first report with a morphological a biomolecular characterization. A 2-year-old Limousine bull was euthanized in the Bolotana (NU) municipality (Central Sardinia). The remote anamnesis achieved from the farmer reporting that the bull showed neurological symptoms from 1 year of age previously classified as nutritional problems by the farm's veterinary. The breeder also says that the bull have by self-produced the skull fracture by hitting a gaff in the farm. The skull was opened and the brain removed and carefully examined showing two coenurus cysts containing clear fluid with numerous scoleces both in the right hemisphere. Morphological features of the cysts and mt-DNA sequencing confirm that the parasites were T. multiceps Coenuri.
多头蚴病是一种中枢神经系统疾病，由多头带绦虫的细囊蚴（Coenurus cerebralis）引起，可感染野生和家养反刍动物。即使在撒丁岛，这种囊尾蚴似乎也广泛存在于绵羊中（Scala 等人，兽医寄生虫学 143(3-4):294-298, 2007），多头蚴病是一个重要的健康问题（Varcasia 等人，寄生虫研究 99(5):622-626, 2006），在牛中最后一次也是唯一一次多头蚴病的报告是在 1990 年（Cubeddu 等人，1990）。本文描述了撒丁岛牛多头蚴病的病例，该病例距首次报告 22 年后进行了形态学和生物分子特征分析。一头 2 岁的利穆赞公牛在博洛塔纳（努）市（撒丁岛中部）被实施安乐死。从农民那里获得的远程病史报告显示，这头公牛从 1 岁开始出现神经症状，此前农场兽医将其归类为营养问题。饲养员还说，公牛曾用角铁击中头部，导致头骨骨折，这是自残行为。打开头骨，取出大脑并仔细检查，发现两个多头蚴囊肿，含有清澈的液体，在右半球有许多头节。囊肿的形态特征和 mt-DNA 测序证实寄生虫是多头带绦虫的多头蚴。
