Abstract

The aim of this study was to determine the fertility and viability of hydatid cysts in slaughtered sheep and cattle. Cysts were collected from the liver and lungs of 169 sheep and 171 cattle infected with Echinococcus granulosus when slaughtered in industrial abattoir in Sari, Iran, 2007–2008. Fertility was determined by the examination of cyst fluid for the presence of protoscoleces. The viability of the protoscoleces was assessed by staining with 0.1% aqueous eosin solution. The fertility rates of hepatic cyst of sheep and cattle were 47.1% and 1.4%, respectively and the fertility rates of pulmonary cyst of sheep and cattle were 39.4% and 8.1%. In the sheep, the fertility of cysts in the liver was higher than that in lungs, but in the cattle the fertility of cysts in lungs was higher than liver. The viability of protoscoleces of fertile cysts for sheep and cattle were about 76.9% and 82.5%, respectively. Based on the finding in the present study, effort should be made to control transmission of cystic echinococcosis by safe disposal of Echinococcus cysts such that dogs cannot have access to the cysts.
