In an abattoir study, 514 camels, slaughtered for meat production in different areas of northern Libya were examined for the presence of cystic echinococcosis (CE). In addition, 367 sheep and 184 goats were examined. The overall prevalence of infection with CE was 48% in camels, 15.8% in sheep and 3.8% in goats. The infection rate, number and size of cysts were significantly higher in older camels. In six city abattoirs across northern Libya, i.e. Zawia, Tripoli, El-Khumes, Mesurata, Sirt and Benghazi, the prevalence rate of infection in camels ranged from 38.7% to 55.2%, in comparison with sheep and goat rates which were between 0% and 37.9% and 0% and 8.2%, respectively. In camels, the lungs were the most frequently infected organs (85.4%) with liver cysts occurring at a significantly lower rate (33%). In contrast, the liver was the predominant infected site with prevalence values of 86% and 100% in sheep and goats, respectively. More than 90% of camel hydatid cysts were fertile. The possible role of camels in the transmission of CE in Libya is discussed.
在一项屠宰场研究中，对在利比亚北部不同地区屠宰用于肉类生产的514头骆驼进行了囊型包虫病（CE）检查。此外，还检查了367只绵羊和184只山羊。骆驼的CE总体感染率为48%，绵羊为15.8%，山羊为3.8%。年龄较大的骆驼的感染率、囊肿数量和大小明显更高。在利比亚北部的六个城市屠宰场，即扎维亚、的黎波里、胡姆斯、米苏拉塔、苏尔特和班加西，骆驼的感染率在38.7%至55.2%之间，而绵羊和山羊的感染率分别在0%至37.9%和0%至8.2%之间。在骆驼中，肺是最常受感染的器官（85.4%），肝囊肿的发生率明显较低（33%）。相比之下，肝脏是主要的感染部位，绵羊和山羊的患病率分别为86%和100%。超过90%的骆驼包虫囊肿是可育的。本文讨论了骆驼在利比亚CE传播中的可能作用。
