2014年11月至2015年4月，在埃塞俄比亚Bishoftu镇的Elfora出口屠宰场进行了一项横断面研究，以评估小反刍动物脑多头蚴的患病率和经济影响。共检查了384只绵羊和384只山羊头，分别发现19只（4.9%）和45只（11.7%）绵羊和山羊受到多头蚴病的影响。两个物种之间的患病率差异具有统计学意义（p<0.05）。小反刍动物脑内囊肿的定位表明，多头带绦虫幼虫期、C。大脑半球最常见（94.7%），其余位于小脑（5.3%）。在大脑半球中，左侧大脑半球包含山羊为64.44%，（47.37%），位于右侧大脑半球（20.0%），绵羊大脑中裂区42.11%山羊为13.33%，绵羊为5.26%，绵羊和山羊小脑均为5.3%。脑囊肿的发生范围为每个脑1至5个囊肿。每年因大脑报废造成的经济损失估计为18，127.2美元（335，353.2 ETB）。结果表明，多头蚴病是埃塞俄比亚小反刍动物的主要寄生虫病之一，给国家造成了巨大的经济损失，应采取相应的防治措施。
A cross-sectional study was carried out at Elfora Export Abattoir in Bishoftu town, Ethiopia from November 2014 to April 2015 to assess the prevalence and economic impact of Coenurus cerebralis in small ruminants. Of a total 384 sheep 384 goats heads examined, 19(4.9%) and 45(11.7%) sheep and goats were found to be affected by coenurosis, respectively. The difference in prevalence between the two species was statistically significant (p<0.05). The localization of cyst in the brain of small ruminants showed that the Taenia multiceps larval stages, C. cerebralis, most commonly found in the cerebral hemispheres (94.7%) and the rest in the cerebellum (5.3%). In the cerebral hemispheres, the left side cerebral hemisphere contained (64.44%) in goats, (47.37%) in sheep, in the right side cerebral hemisphere (20.0%) in goats, (42.11%) in sheep, in the median fissure of the cerebrum (13.33%) in goats, (5.26%) in sheep and the rest in the cerebellum (5.3%) both in sheep and goats Postmortem examination had showed that C. cerebralis occurred with a range of 1 to 5 cysts per brain. The total annual financial loss due to brain condemnation was estimated at 18,127.2 USD (335,353.2 ETB). Based on this study, it was concluded that coenurosis was one of the most important parasitic diseases in small ruminants in Ethiopia which resulted in great economic loss at national level and therefore, appropriate control measure should be taken.
