“…The reverse was noticed in pulmonary cysts, where the fertility rate was higher in camels than in sheep because the lung of the camel is a more suitable organ for fertile cyst, as it is known to have a more conducive habitat for the growth of the metacestode [31]. The findings from the present study are supported by those from Libya and Iran [10] [11] [29]. Furthermore, the findings from Iran observed that the hepatic cysts of sheep were more fertile than pulmonary cysts, while other from Jordan found hepatic cysts from sheep were more fertile than those from the camel [27] [32].…”

The present study reports on the infection rates of hydatid cysts in both sexes and different age groups of sheep, camels and cattle from government abattoirs in different parts of Libya. An infection rate of 10.06% was recovered among 32,971 all ruminants (sheep, camels and cattle). Out 25314 of sheep, 2659 (10.52%) were infected. Out 7496 of camels, 940 (12.54%) were infected. Out 161 of cattle, 17 (10.56%) were infected. As regards to the infected organs, liver was seen to be the most commonly infected organ in sheep and cattle (46.03%; 52.94%, respectively), but in camels, it was the lung (55.21%). The fertility rates of hydatid cysts were 80% in sheep, 84% in camels and 0% in cattle. In sheep, the fertility rate of liver hydatid cysts was higher than that in other organs (53.85%), but in camels, the fertility rate in the lung was higher than that of other infected organs (66.7%). Thus, the incidence of echinococcosis in slaughtered livestock is noticeably high and denotes some hazards in control measures in Libyan abattoirs.

“…Recently, Daryani et al (2009) reported that in an abattoir in Sari, Mazandaran Province, 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.…”

A study was conducted to assess the ruminants' hydatidosis in Mazandaran Province, Northern Iran. A total, 1,799 sheep, 985 goats and 362 cattle slaughtered at Sari industrial slaughter house were examined for hydatid cyst infection. The results indicated that 65.2% of sheep, 37.8% of goats and 40.1% of cattle were infected. The liver and lung infection rate in sheep were 18.8 and 4.3%, goats 17.2 and 12.6% and cattle 44.1 and 7.6%, respectively. The study showed that 766 (45.3%) out of 1,691 infected animals had moderate degree of infection. Geographical zone survey indicated that 1,381 (89.2%) out of 1,546 sheep and goats infected with hydatid cyst were non-indigenous and originated from north-eastern provinces of Iran. On the contrary, 50.3% of infected cattle originated from Mazandaran Province (indigenous).

“…Intermediate hosts, as sheep, goats, cattle, camels, buffaloes, pigs, horses and donkeys can be infected by eggs ingestion. The dog-sheep cycle has been reported to be predominant in Southern Europe and Mediterranean Basin [7]. Humans, considered as "dead-end" host, can be accidentally infected acting as intermediate hosts.…”

Introduction: Cystic Echinococcosis (CE) is one of the most widespread zoonosis of veterinary and medical importance still constituting a sanitary, economic and socio-cultural problem in Italy. Methodology: The aim of this study was to update epidemiological data on cattle CE in Italy. Data on CE positivity of 5,336 cattle were acquired from abattoir registers between January 2009 and July 2010. Morphobiological characterization of hydatids was performed by direct examination of liver and lungs of 1,664 animals butchered in the same slaughterhouses in 2010. Strain typing of parasites was carried out through the amplification and sequencing of nd1 and cox1 mitochondrial genes. Results: Overall CE prevalence was of 8.1% (430/5,336). Parasitological examination of hydatids showed an overall prevalence of 8.6% with a fertility rate of 0.7% (12/1,664). Regarding localization, hydatids were found in 8% of the livers and in 7.6% of the lungs, respectively. Among positive animals, higher prevalence was observed in the liver (93%) compared to lungs (88.1%) (p > 0.05). Conclusion: The economic loss due to organs condemnation related to CE in cattle amounted to almost € 24,000 per year in the examined abattoir during 2010. Sequence analysis showed the presence of G1 (sheep strain) or Echinococcus granulosus sensu strictu in all examined samples. The G1 confirmed, once more, its possible development into several intermediate hosts such as cattle, especially in areas like southern Italy and Sardinia where the lifecycle of the parasite is still to date carried on by sheep and dogs.
