Coenurosis is a disease of the central nervous system in sheep. A survey was carried out to assess the occurrence of in Madras red sheep. A prevalence rate of 12.30 % observed when 122 slaughtered Madras red sheep were examined in an organized farm during 2002 to 2007 at Livestock Research Station, Kattupakkam, Tamil Nadu, India. The skulls of the animals were opened to know the prevalence of cyst in the brain. Out of 12.30 %, only 3.28 % sheep showed clinical signs while the remaining were apparently healthy (9.02 %). cysts were observed in cerebrum, cerebellum and on spinal cord, averaging 66.67, 26.67 and 6.66 %, respectively. Among different age groups of sheep, highest infection rate was observed in rams (20.69 %) followed by ewes (10.00 %), young males (9.09 %) and young females (8.33 %). Males (17.50 %, 7/40) were more infected compared to the female sheep (9.76 %, 8/82). Grossly, ventral cerebrum was congested and depression in sulci was noticed. Posterior portion of the skull showed severe congestion and haemorrhage. Severe congestion was also noticed on the gyri of right cerebral hemisphere.
多头蚴病是绵羊中枢神经系统的一种疾病。开展了一项调查以评估马德拉斯红羊多头蚴病的发生情况。2002年至2007年期间，在印度泰米尔纳德邦卡图帕克姆的家畜研究站的一个规模化养殖场对122只屠宰的马德拉斯红羊进行检查时，观察到患病率为12.30%。打开动物的头骨以了解脑中多头蚴囊肿的患病率。在12.30%的患病率中，只有3.28%的绵羊表现出临床症状，其余的显然健康（9.02%）。在大脑、小脑和脊髓中均观察到多头蚴囊肿，分别平均占66.67%、26.67%和6.66%。在不同年龄组的绵羊中，公羊的感染率最高（20.69%），其次是母羊（10.00%）、青年公羊（9.09%）和青年母羊（8.33%）。雄性绵羊（17.50%，7/40）比雌性绵羊（9.76%，8/82）感染更严重。大体上，大脑腹侧充血，脑沟有凹陷。颅骨后部显示严重充血和出血。右侧大脑半球的脑回也有严重充血。
