Two rare clinical manifestations of coenurosis in sheep are reported. (i) A case of partial seizure disorder in a ram of 11 months old. During seizure episodes the animal lay down in lateral recumbency displaying initially a stuporous condition and subsequently began to revolve its head from the base of the cervix. At the necropsy of the case, Coenurus cerebralis cyst (young bladder worm) was found dorsally inside the brainstem, in the site of the tectum mesencephaly. (ii) The second-reported manifestation was a bacterial meningoengephalitis that was witnessed in two lambs of 6-7 weeks old. The lambs displayed lateral recumbency with seizure activity. At necropsy, meningoencephalitis with congestion and abscesses were observed in both of them. Interestingly, C. cerebralis cysts were also found in both brains. Streptococcus dysgalactiae was isolated from the abscesses. Possibly, S. dysgalactiae translocation of the blood-brain barrier was facilitated by the migration of the immature stages of C. cerebralis to and through the brain.
报告了绵羊多头蚴病的两种罕见临床表现。(i) 一例11月龄公羊的部分癫痫发作障碍。在癫痫发作期间，动物侧卧，最初表现为昏迷状态，随后开始从颈部基部旋转头部。在该病例的尸检中，在脑干背侧中脑顶盖部位发现了脑多头蚴囊肿（幼囊尾蚴）。(ii) 报告的第二种表现是在两只6 - 7周龄的羔羊中出现的细菌性脑膜脑炎。羔羊侧卧并伴有癫痫活动。尸检时，在它们两者中均观察到伴有充血和脓肿的脑膜脑炎。有趣的是，在两个大脑中也都发现了脑多头蚴囊肿。从脓肿中分离出了停乳链球菌。可能是脑多头蚴未成熟阶段向脑部迁移并穿过脑部促进了停乳链球菌突破血脑屏障。
