“…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 a study by Scala et al that to do in Italy in 2006 the prevalence rate of hydatid cyst 75% reported [22]. Also Saeed et al during the period 1990-1998, 1270 sheep, 550 goats and 320 cattle were examined at slaughter for hydatid cysts and prevalence rates were found to be 15.0%, 6.2% and 10.9%, respectively [23]. In the Scala and Saeed studies like our study, the highest frequency of cysts was in sheep.…”

In Saeed et al study between 63% and 82% livers and between 72% and 79% lungs were contaminated [23]. Molan in his study that performed on sheep, liver with 6.5% and lung with 3.8 were infected [24].…”

Background: Hydatidosis or echinococcosis is one of the most important economic and public health problems in many regions of the world that livestock are kept such as Iran. This study was to determine the prevalence of hydatid cyst in slaughtered livestock in Kermanshah (west Iran) (2012). Methods: This descriptive-analytic study was carried out on all slaughtered livestock during 24 months period, from March 2012 until February 2013. 70,020 carcasses were observed and inspected (including: 24,507 cattle, 35,010 sheep and 10,503 goats). All cysts were examined under direct microscopy for determine the kind of cysts (fertile and infertile cyst). Results: The prevalence of hydatid cyst was 2.20% in cattle, 2.78% in sheep and 0.19% in goat. Liver in cattle with 1.42%, in sheep with 2.25%, and in goat with 0.13% was contaminated. Also lung in cattle with 0.76%, in sheep with 0.53%, and in goat with 0.06% was contaminated. Heart was contaminated only in cattle with 0.024%. Sheep with 45% and goat with 90.47% had highest fertile cyst and infertile cyst, respectively. Conclusion: The prevalence rate of hydatid cyst in slaughtered livestock in Kermanshah was lowest, as compared with other regions of Iran. Despite this, hygienic programs should be done in order to decrease, control and prevent of parasitic infection.

“…Hydatid disease is most extensively found in East and North Africa, India, Australia, New Zealand, South America, and Middle East including Iran [1][2][3][4][5][6][7][8][9]. Mostly the rate of the infection in carnivores such as dog and herbivores such as sheep, camels are significant but humans also get the infections accidentally [10][11][12][13][14][15][16], hereby, hydatidosis is a major health-economic problem, that has become one of the WHO`s active plans for controlling the disease [17].…”

Echinococcosis/hydatidosis is a zoonotic disease. The disease is caused by adult worms and larval (metacestode) stages of the taeniid cestode Echinococcus granulosus. The life cycle is completed into two hosts. The final host usually carnivore e.g. dog, and the intermediate host usually herbivorous and man. The aim of this study is to evaluate the fertility of cysts and viability of protoscoleces in man and camel hydatid cysts in order to determine the prevalence of their fertility and to study the association with variables typical of host and of the parasite. Material and methods:Across-sectional and observations study was done in biological material (the fluid from human and camel hepatic and lung hydatid cysts). The viability criteria used were ovoid form invaginated scolices and intact calcareous corpuscles. The presence of vibrating movements, and the absence of "vital" staining, the cysts were grouped in diameter cysts from small cysts to very large size of cysts. Descriptive statistics were for the calculation of the prevalence of fertility, analytical statistics for comparison of groups, and multivariate analysis for examination of the association between cyst fertility and clinical variables. Results:A total of 99 cysts with less than 2 cm 5 (7.8%), from 2-6 cm 52 (81.2%,) medium diameter 6-10 cm 37 (57.8%), and more than 10 cm 5 (7.8), and prevalence of general fertility 68%, sterial cysts was 6%, supporative was 10% and calcified was 15%. Most of camel fertile cysts had medium size (81.2%), while the lowest rate belongs to the small cysts (7.8%). There was significant relationship between fertility of the cyst, type of infected organs, type of animals and size of cyst. Association with location, type, and diameter of the cyst, the viability Protoscoleces was assessed by microscopic observation of biological feature represented by muscular movements, flame cell activity in 0.1% aqueous eosin stain. Conclusion:The differences between prevalence rates, the fertility of hydatid cysts and diversity sites localization observed in humans and camels. Fertility is associated with the type of cyst, location type, type of animal and size of cyst.
