“…The fertility rate of hydatid cysts in sheep reported in the literature varies in different regions of the world. Cyst fertility rates in sheep were reported as 84% in Saudi Arabia (Farah, 1987), 90% in India (Singh and Dhar, 1988), 7.6% in Sardinia (Bortoletti et al, 1990), 51% in Greece (Himonas et al, 1994), 38.1% in Jordan (Kamhawi et al, 1995) and 64% in Iraq (Saeed et al, 2000). The cyst fertility rate in sheep of the Kirikkale region was similar to that known from previous studies reported in Turkey as 61.2% (Senlik, 2000) and 93% (Guralp and Dogru, 1971).…”

This study was conducted in order to determine the prevalence and fertility of hydatid cysts in sheep in Kirikkale, Turkey. A total of 3.2% of 553 lambs and 50.9% of 1320 adults were found to be infected with hydatid cysts. The most common locations of cysts were in the liver and lung. Liver cysts tended to be more fertile than lung cysts (81.53% v. 76.47%), though the difference was not significant. The mean number of viable protoscoleces in the liver and lung cysts were 12,400 and 5,800, respectively. In general, 1-10 cysts were found in liver (51.8%) and lung (64.7%). The findings of this study indicate that hydatid cysts are common in sheep and the fertility rate of cysts is quite high. Sheep play an important role in the life cycle of Echinococcus granulosus in this region.

In this crossectional survey the prevalence, fertility, size of hydatid cyst in cattle and sheep, economic losses due to hydatidosis in cattle, and prevalence of Echinococcus granulosus in dogs were studied in South Wollo, Ethiopia. for the purpose Each animal carcass was inspected carefully, hydatid cysts of each organ were counted, measured and examined microscopically to determine the fertility and determination of infection of Echinococcus granulosus in the dog involved in the study was done by standard post-mortem procedure. Of the total of 312 cattle and 197 sheep examined 56 (17.95%) and 15(7.61%) were found to be infected with hydatid cysts respectively. The prevalence in cattle tended to be high, though the difference was not statistically significant (P> 0.05, X 2 =1.006). Lung was found to be the most commonly affected organ in case of cattle, liver in case of sheep with a value of 66.25%and 82.36% respectively. Spleen and heart were found to be less commonly affected organs in cattle and lung in case of sheep, cysts were not observed in the kidney in both species. Studies on the condition of the cysts revealed that medium sized cysts predominate in case of cattle with an abundance rate of 54.9%, followed by small cysts (40.8%) and large cysts (4.3%). All of the cysts found in sheep were small and majority of them showed calcification. Cyst fertility rates were 36.2% and 45.5% in lung and livers respectively (z = 0.46, P = 0.643). Out of 10 stray dogs euthanized and examined at necropsy 2(20%) were found to be infected with adult E.granulosus with a mean worm burden of 30. An annual loss of 464,900 Eth.birr was estimated to be caused by bovine hydatidosis from organ condemnation and carcass weight losses. In conclusion this zoonotic cestode need deserve due attention in order to safe guard the public and reduce the economic losses in animals, Hailu Degefu, et al.

Hydatidosis: Dynamics of Transmission

Hydatidosis is a widespread zoonosis infecting a large number of animals and humans. Echinococcus granulosus has the smallest taenia adult of the cestodes but with the largest larva. Its morphologic and biologic features were identified with DNA analysis. Different strains were separated according to the intermediate hosts: sheep, cattle, pigs, horses, camels. Definitive host are canids, mostly dogs, where the worm grows to adulthood in several months. The eggs are scattered in the pasture by wind and water and are ingested by various hosts. The larvae migrate through the intestinal wall and penetrate the organs, mostly liver and lungs. The eggs survive several days outside, depending on the temperature, but numerous eggs die in nature because they cannot resist desiccation and extreme temperatures. Dissemination is accomplished by dogs. In Turkana (Kenya) the incidence of hydatidosis is high because of the close relationship between the population and dogs and the habit of leaving their dead bodies in the grasslands. In rural areas, the custom of slaughtering sheep at home, among the dogs, is an important dissemination factor. The circumstances of transmission vary according to the country. In Europe the natural life cycle of E. granulosus granulosus involves dogs as the definitive host and sheep as the intermediate host. In northern Europe E. granulosus borealis infects the canids and deer. E. granulosus canadensis infects wolves and reindeer, but there are no human cases. In the endemic Mediterranean area, sheep and dromedaries are the intermediate hosts. In South America, the life cycle of E. granulosus develops among several definitive and intermediate hosts. Hence the dynamics of transmission vary according to the countries with different hosts.
