Abstract: 

Hydatidosis is a widespread zoonosis infecting a large number of animals and humans. Human hydatidosis is a common disease in different parts of Iran especially in Hamadan province. Many cases of cysts are operated every year in regional hospitals. Animal echinococcosis prevalence was determined by necropsy examination of viscera from domestic slaughtered animals, including sheep, goats and cattle.
After inspecting viscera for hydatid cyst, unilocular cysts produced by E. granulosus were recovered from 212 out of 2000 domestic herbivores (1547 sheep, 333 cattle and 120 goats) slaughtered in Hamadan abattoir. The number of cyst of different organs was counted and their diameter was measured. Thereafter, by dissecting the cysts, the volume of hydatic fluid was measured, and their fertility was determined by finding protoscoleces and the number of protoscolex per/ml fluid was counted.
The frequency of presumptive liver/abdominal, lung, and liver-lung hydatid cyst was 15.3% (51/333), 10.6% (159/1547) and 1.7% (2/120) for cattle, sheep and goats respectively. The fertility rate of hydatid cysts in sheep, cattle, and goats recorded as 35.2.%, 23.5% and 0% respectively. The huge dispersed slaughtering of sheep for various purposes and the large number of dogs allowed access to the offal coupled to the hundred thousands number of sheep slaughtered in Haj Pilgrim days, indicates that, the sheep is the most significant host for maintaining the life cycle of the parasite in Iran.
We demonstrated a high prevalence of animal echinococcosis in this mountainous, agricultural province of Iran.
