“…This is in fundamental agreement with literature, which states that hydatid cysts are most commonly found in the liver and lungs of ungulates (Soulsby, 1986;Urguhart et al, 1988;Yilma Jobre et al, 1996;Getaw et al, 2010;Ibrahim, 2010;Nigatu Kebede, 2010). This could be justified by the fact that lungs and liver posses the first greater capillary fields which acts as partial barriers for the ingested oncosphere which adopt the portal vein route and primarily negotiates the hepatic and the pulmonary filtering action sequentially before any other peripheral organ is invaded (Matosain, 1977).…”

“…The mean prevalence value reported in the present work concords with the recently reported prevalence of 34.05% in cattle and 10.6% in sheep from Bahir Dar (Nigatu Kebede et al, 2009c), 32.11% in cattle from Mekelle (Gebretsadik Berhe et al, 2010) and 29.69% in cattle from Ambo (Endrias Zewdu et al, 2010). Slightly higher prevalence of 48.9% in cattle from Debre Markos (Kebede Nigatu, et al, 2009a), 46.8% in cattle, 29.3% in sheep, and 6.7% in goats from Nazareth (Getaw et al, 2010) and 52.69% in cattle from Hawassa (Feyessa Regassa et al, 2010) were also reported. A retrospective survey of bovine hydatidosis conducted in Gondar, Injibara and Finote Selam municipal abattoirs during 2002 to 2007 revealed an increasing trend from year to year in prevalence of bovine hydatidosis that caused the condemnation of 79.5% organs (Nigatu Kebede, 2010).…”

“…Several studies have been conducted on livestock hydatidosis in different parts of the Ethiopia, particularly through the externship program of the Faculty of Veterinary Medicine (FVM), Addis Ababa University (AAU). However, most of these works were unpublished and not readily available to the wider national and international readership (Getaw et al, 2010;Lemu Golassa et al, 2011). As hydatidosis is considered a serious problem for public health and the livestock economy in Ethiopia, the present paper reviews and summarizes available data on the disease in the country.…”

Hydatidosis/echinococcosis (Echinococcus granulosus, Batsch, 1786) is considered to be a serious problem for both public health and the livestock economy in Ethiopia. The present paper reviews and summarizes available data on the disease. Abattoir survey data collected over a period of 15 years (1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999) were analyzed to assess the infection prevalence of hydatidosis in domestic animals in three different agroecological zones of Ethiopia. Accordingly, 8036/22,863 (35.15%) cattle, 768/6518 (11.78%) sheep, 36/1753 (4.9%) goats, 70/417 (16.79%) camels and 0/150 (0%) pigs slaughtered in 21 different abattoirs located in various parts of the country were found harbouring hydatid cysts. A statistical discernible significant difference (p<0.001) was observed in the overall hydatidosis infection prevalence between the different species of animals, and in infection prevalence of bovine hydatidosis in the three agroecological zones where the slaughtered cattle were believed to originate from. Similarly, a statistically significant difference (p<0.01) in the prevalence of ovine hydatidosis was observed between mid-altitude and lowland agroecologies. Conversely, there was no significant difference (p>0.20) in the infection prevalence of caprine hydatidosis between mid-altitude and lowlands. The present study reconfirms that hydatid disease is widespread and highly prevalent in ruminant livestock in Ethiopia and warrants institution of a nation-wide control measures. Considerations on experiences of other countries with respect to the economic benefits that hydatid disease control programs may bring to livestock producers and combining such efforts with other zoonosis control schemes in view of the 'one health' initiative is worthy for animal health planners and policy decision-makers. The paper also serves as a quick reference source on hydatidosis in the country and basis for future studies.

“…Prevalence of cattle hydatidosis (17.95%) in the present study agrees with previous findings in different corners of the country and other parts of the World, such as the works of Jemere Bekele and Berhanu Butako (2011 However, the prevalence of hydatidosis recorded in cattle in this study can be seen as a lower level of infection when compared to the highest recent prevalence reports else where in Ethiopia (Getaw et al, 2009;Nigatu Kebede et al, 2009;Tadele Tolosa et al, 2009;Endrias Zewdu et al, 2010). Cattle hydatidosis studies in other countries also show higher prevalence than the present study including that of 38.…”

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.

“…This difference could be attributed to the fact that cattle are slaughtered at old age, while sheep and goats are slaughtered at a relatively early age compared to cattle. Aging can increase the risk of exposure to eggs of E. granulosus in cattle (Getaw et al 2010).…”

Hydatidosis is one of the important zoonotic diseases that cause considerable economic losses and public health problems worldwide. This study was conducted to determine the prevalence Echinococcus granulosus in people and slaughtered animals in Kermanshah province, west of Iran. Hospitals data and meat-inspection records in Kermanshah abattoir were used in this study. A total number of 32,130 slaughtered livestock (7000 cattle, 19,950 sheep and 5180 goats) was inspected in the 3-year period and overall 2043 (6.35 %) were infected. The highest and lowest prevalence was recorded in cattle and goats, respectively. In human, Cystic echinococcosis affected more females (54 %) than males (46 %) with a 1.17 male to female ratio. Rate of disease in urban and rural regions were 46 and 54 %, respectively. The youngest and the oldest patient operated were 7 and 87 years old, respectively, and the age group 21-40 years (41.2 %) were the most affected. A significantly higher number of hydatid cysts were recorded in the liver than in other sites. The ratio of hepatic hydatidosis to pulmonary hydatidosis was 2.46. The results showed that hydatidosis is of great importance in this area and serious attention is needed to prevent and control the disease.
