Abstract

Hydatidosis, caused by Echinococcus granulosus, is a cyclozoonotic disease of economic significance in Sardinia. The life-cycle involves stray and sheep dogs as definitive hosts and sheep, pigs, goats and cattle as intermediate hosts. The most important intermediate host is sheep, due to home slaughtering with ready access of the viscera to dogs. This survey was undertaken in 1987 to ascertain the epidemiological significance of sheep in maintaining the life-cycle. A total of 700 (91.3%) of 767 sheep harboured hydatid cysts. The frequency distribution of the number of hydatid cysts was over-dispersed. Of 497 infected sheep, 7.6% had fertile cysts, 75.7% sterile cysts and 16.7% fertile + sterile cysts.

摘要

由细粒棘球绦虫引起的包虫病是撒丁岛一种具有经济意义的环虫病。其生命周期涉及流浪犬和牧羊犬作为终末宿主，绵羊、猪、山羊和牛作为中间宿主。由于家庭屠宰时内脏易被犬接触到，所以最重要的中间宿主是绵羊。这项调查于1987年进行，以确定绵羊在维持生命周期中的流行病学意义。767只绵羊中共有700只（91.3%）感染了包虫囊肿。包虫囊肿数量的频率分布呈过度分散状态。在497只受感染的绵羊中，7.6%有可育囊肿，75.7%有无菌囊肿，16.7%有可育+无菌囊肿。
