Hydatid cyst or cystic echincoccosis (CE) is an important medical and veterinary problem in the world, especially in Iran. Domestic intermediate hosts are a major reservoir for the disease in humans. The aim of this study was to determine the prevalence of hydatid cysts in slaughtered animals in Isfahan, central part of Iran.
In this cross-sectional study performed from 10 May 2009 to 10 May 2010, a total of 196,325 animals (89,651 sheep, 93,050 goats, 9,112 cattle and 4,512 calves) were inspected macroscopically for hydatid cysts.
Prevalence rate of CE in sheep, goats, cattle and calf was 16.4%, 3.1%, 6.5% and 8.2%, respectively. In all cases, the prevalence in female cattle and sheep was more than in males (P < 0.001). There are significant seasonal pattern for hydatidosis only in sheep (P < 0.001) and the highest prevalence of cysts was seen in autumn and winter seasons. The fertility of cysts in the liver of sheep (77%) was higher than in lungs (47.9%), but was higher in lungs in cattle (44%). Most condemnation cases were seen in lung of sheep (27.1%).
It appears that sheep are the most important intermediate hosts for E. granolusus in this area.
包虫囊肿或囊型包虫病（CE）是一个在全球尤其是伊朗存在的重要医学和兽医问题。家畜中间宿主是人类该疾病的主要传染源。本研究旨在确定伊朗中部伊斯法罕地区屠宰动物中包虫囊肿的患病率。
在这项于2009年5月10日至2010年5月10日进行的横断面研究中，对总共196,325只动物（89,651只绵羊、93,050只山羊、9,112头牛和4,512头小牛）进行了包虫囊肿的宏观检查。
绵羊、山羊、牛和小牛的囊型包虫病患病率分别为16.4%、3.1%、6.5%和8.2%。在所有病例中，雌性牛和绵羊的患病率高于雄性（P < 0.001）。仅在绵羊中包虫病存在显著的季节性模式（P < 0.001），囊肿患病率在秋季和冬季最高。绵羊肝脏中囊肿的繁殖力（77%）高于肺部（47.9%），但牛肺部的繁殖力更高（44%）。大多数被判定不合格的病例出现在绵羊的肺部（27.1%）。
在该地区，绵羊似乎是细粒棘球绦虫最重要的中间宿主。
