In the Ouarzazate province of Southern Morocco, 1085 cattle and 358 sheep were examined for hydatid cysts. The prevalence was 44.6% (range 8.3-83.4%) in cattle and 5.3% (range 1.3-28.6%) in sheep. The prevalence increased with the age of the animals. The lung was the predominant site of infection, followed by the liver. In cattle, 14.2% of hydatid cysts were fertile and 16.4% had degenerative changes. The mean loss per head of cattle slaughtered was about 1 kg of liver and 900 g of lungs in the urban abattoirs. In monetary terms at the current price of 1980, this meant a loss of U.S. +4.5 at urban and +1.6 at rural abattoirs. The mean prevalence of infection in 61 stray dogs was 50.8%, with a mean worm burden of 413. The urban dogs had a lower infection rate (42.9%) than the rural dogs (61.5%). There were 130 dogs per 1000 inhabitants. The human population was ignorant of the life-cycle of Echinococcus granulosus and was not aware of risk of infection through dogs. Dogs become infected at abattoirs, at home slaughter and in the field by consuming dead carcasses. The maintenance and transmission of E. granulosus in animals and man is related to social, religious and cultural factors.
在摩洛哥南部的瓦尔扎扎特省，对1085头牛和358只羊进行了包虫囊肿检查。牛的患病率为44.6%（范围8.3 - 83.4%），羊的患病率为5.3%（范围1.3 - 28.6%）。患病率随动物年龄增长而增加。肺部是主要感染部位，其次是肝脏。在牛中，14.2%的包虫囊肿是有活力的，16.4%有退行性变化。在城市屠宰场，每头屠宰牛的平均损失约为1千克肝脏和900克肺脏。按1980年的现行价格计算，这意味着城市屠宰场损失4.5美元，农村屠宰场损失1.6美元。61只 stray狗的平均感染率为50.8%，平均虫负荷为413。城市狗的感染率（42.9%）低于农村狗（61.5%）。每1000名居民中有130只狗。当地居民对细粒棘球绦虫的生命周期一无所知，也没有意识到通过狗感染的风险。狗在屠宰场、家庭屠宰和野外通过食用死畜尸体而感染。细粒棘球绦虫在动物和人类中的维持和传播与社会、宗教和文化因素有关。
