“…Bosely (2014) observed higher rates of fertile cysts in sheep and goats (81% and 39.06) than the sterile (13% and 35.93%) and calcified (6% and 25%), respectively. In contrast also Chaligiannis et al(2015) reported that cyst fertility was constantly higher in lungs than liver in both sheep and goats (4% and 2.7%; 2.4% and 0.45%, respectively). while in cattle; the number of sterile cyst was higher (79.03%) than the fertile and calcified cysts (17.74% and 3.22%), respectively.…”

Abstract:Cystic echinococcosis (CE) or hydatid cyst (HC) caused by the larval stage of the tapeworm Echinococcus granulosus continues to be a substantial cause of morbidity and mortality in many parts of the world. Since Kurdistan region is considered as endemic area, an epidemiological study was conducted to investigate the occurrence of CE isolated from sheep, cattle and goats from July 2013 to June 2014. The total rate of infection was 11.17(457/4092), with the highest rate (9.07%) in sheep and the lowest (0.54%) in goats. Regarding the sex of the infected animals, female showed slightly a higher rate than males (5.99% versus 5.18%) which statistically non-significant (P>0.05). Among the three intermediate host sheep showed the highest rate of infection (14.51%) regarding the sex females of sheep and cattle showed higher rate of infection versus males (27.36 and 20.35 versus 9.37 and 3.86). Furthermore, the highest incidence of CE in sheep, cattle and goats were found among the age group over three years (18.75, 5.41 and 1.69%, respectively), while the lowest rate was noted in the age groups less than one year (3.96 and 0.25%, o.33, respectively). On the other hand, sheep showed high rate of infection throughout the year with peaks during May to July which were 19.44%, 17.59 and 18.14%,respectively. This was followed by cattle and goats (11.67% and 5.26%) in April and December, respectively. Regarding the size, the higher numbers of small sized cysts were found in the liver (98/175), while the highest numbers of large sized cysts were found in both liver and lung which were 69/165. The liver and lungs appeared to be the site of predilection, since highest rate of infection was reported in these organs. Regarding the fertility of CE, the highest was in sheep (87.6%), followed by goats (77.27%) and then the cattle (40.63%).

“…A control programme has been in force since 1984, and surveillance in livestock species since 1998 has documented prevalences of 31.3% in sheep, 10.3% in goats, 0.6% in pigs and 0% in cattle (Sotiraki et al, 2003). A survey conducted by Chaligiannis et al (2015) conducted an epidemiological survey in different geographical regions of Greece (Thrace, Thessaly, Western and central Macedonia). In the Thrace region, hydatid cysts were found in 33.3% of sheep, while prevalences were 30.3% and 26.1% in sheep of western and central Macedonia, respectively.…”

“…This indicates the endemicity of CE in buffaloes at Mansoura, Dakahlia province. Diversified prevalences were reported from different countries such as 42% in Greece [18], 8.7% in Italy [19], 3.81% in India [10], 9% in Iran [20], and 7.19% in Pakistan [21]. …”

“…Our molecular results indicated the homogeneity of those cysts with G1 genotype (common sheep strain). Furthermore, the previous reports discussed the low fertility rate of hydatid cysts of buffaloes (7.3%) and their relation to the G1 [18,20]. While in Pakistan, where the G3 (buffalo strain) was the prevalent genotype, the fertility rate was high (84.3%) [21].…”

“…Previously, 2 samples from the Egyptian buffaloes were characterized as G6 which not described before from buffaloes worldwide [13]. Considering reports from buffalo rearing countries (Table-3), G1 was the widely dispersed genotype in Iran [24]; India [25], Pakistan [26], Italy [27], Turkey [8], and Greece [18]. Although, G3 (buffalo strain) and G5 (cattle strain) were recorded but in few cases [7,21,25,28].…”

Aim:Cystic echinococcosis (CE) represents a serious parasitic disease at both animal and public health levels. The majority of reports negated the CE infection in buffaloes from Egypt; however, one study illustrated their infection with G6 genotype (camel strain). The present work contributed to update the epidemiological and molecular knowledge about CE infecting this economically important animal for better understanding of its role in maintaining the Echinococcus life cycle.Materials and Methods:A total of 120 slaughtered water buffaloes at Mansoura abattoir, Dakahlia province, Egypt, were inspected for the existence of hydatid cysts. Cysts location and fertility were examined. Five out of 27 revealed cysts were tested molecularly using both cytochrome C oxidase subunit 1 and nicotinamide adenine dinucleotide hydrogen subunit 1 (nadh1) genes.Results:Low prevalence (4.2%) as well as considerably low fertility rate (14.8%) of buffaloes CE was noted. G1 genotype (common sheep strain) was revealed from the five examined cysts. At the level of nadh1 partial sequences, a globally singleton G1 haplotype was reported.Conclusion:This the first report about the G1 infection in buffaloes from Egypt. This study proposed the minimized role of this animal in echinococcosis transmission. These findings could provide preliminary data for the local control of this disease.
