Comparative aspects on fertility r and viability of hydatid cyst from goat, camel and buffalo in Thi-Qar Province-Southern Iraq

الملخص EN

The fertility and viability rates of hydatid cysts obtained from livers and lungs of goat,camels and buffaloes were investigated .Out of (659) cysts (198 from goat,241 from buffaloes and 220 from camels) .examined ,520(164 from goat ,156 from buffaloes and 200 from camels were fertile (containing living protoscolices).The mean viability rates in -the liver cysts of goat camel and buffalo were (77.4%, 76.8% and 76.7%) respectively whereas those in the lung cyst of the same hosts,in the same order were 81.2% 75% and - 84.65% respectively.

The growth rate of lung cysts was slower than those of liver in all hosts investigated.

.

Three hosts investigated seem to be suitable hosts for Echinococcus granulosus .However ,goats seem to be the most significant host that contributes actively in A perptuation of life cycle of this parasite in Iraq .
