“…This matter can be supported by the relationship between increasing age and risk of hydatidosis, since the most of older slaughtered livestock are often female. These results are compatible with the previous study which is conducted in Hamadan (8) and other reports area (10,11,15). In contrast to our study, the frequency of hydatid cyst in liver was higher than lungs in slaughtered animals that inspected in Yemen in 2012 (16).…”

“…Another finding in this study showed that 5.3% of the slaughtered cattle were infected with CE, more than sheep and goats. In Iran, CE in cattle has ranging from 1% to 28% with the mean of 12% based on some previous investigations (8,9,11,12). However, there is a report of high prevalence on cattle hydatidosis (38%) in Ardabil province (10).…”

“…The results of our study revealed that 3% of sheep were infected with hydatid cyst. In most studies, the frequency of hydatidosis in goat was lower than other livestock intermediate host species, probably because of the feeding of goats through browsing rather than grazing (6,8,9,(11)(12)(13). In accordance with reports, the infection rate of goats in this study was significantly lower than sheep and cattle with frequency of 1%.…”

Background: Cystic echinococcosis (CE) is a cosmopolitan zoonotic infection which is considered as a significant public health and economic concern. Livestock is the main intermediate host for Echinococcus granulosus. Objectives: This study was conducted to evaluate the prevalence and fertility rate of hydatid cyst among livestock in Hamadan area, western Iran. Methods: A total of 10626 livestock carcasses were examined through visual inspection in order to detect hydatid cyst in Hamadan industrial slaughterhouse, during 2015 -2016. The viability and fertility of hydatid cyst were determined microscopically by flame cell activity and eosin dye uptake. Results: The carcasses, including 8684 sheep, 1110 goats and 832 cattle were inspected in order to detect hydatid cyst. An overall CE was detected in 3% of the inspected carcasses with a prevalence rate of 5.3% in cattle, 3% in sheep and 1% in goats (P < 0.001). The prevalence rate of infection in the females (2.7%) was more than males (0.3%) (P < 0.001). All of the infected animals were aged one year or more. The highest rate of infection in internal organs was found in the lungs (47.2%). The highest and the lowest fertility rate of hydatid cyst were observed in sheep (69.3%) and cattle (6.8%), respectively. The most of hydatid cysts which obtained from cattle (79.6%) were suppurative or calcified. Conclusions: This study shows that the prevalence rate of CE is considerable in the area and sheep appear to be the most important intermediate hosts for E. granulosus tapeworm.

“…Another epidemiological study of hydatidosis in the camels from different regions of Iran showed that 42.8 % in Khorasan Razavi Province, 17.8 % in Yazd province, 22.8 % in South Khorasan province, 4.28 % in Semnan province, and 12.14 % in Sistan and Baluchestan province were positive (Moghaddas et al 2014). Prevalence rate of hydatidosis in sheep, goats, cattle and calf was 16.4, 3.1, 6.5 and 8.2 %, respectively in Isfahan province, Iran (Azami et al 2013). Based on our knowledge, there is no previous study regarding the prevalence of equine hydatidosis in Iran.…”

Hydatidosis, is an important worldwide zoonotic disease caused by larval stages (metacestodes) of tapeworm parasites of the genus Echinococcus. The objective of the present study was to determine the seroprevalence of equine hydatidosis in Iran by latex agglutination test. This study also served to correlate sex and age with mentioned results in cases. Therefore, 193 serum samples were collected from clinically healthy horses at 9 race clubs in Kerman, Yazd and Golestan provinces, Iran. According to the results, antibodies against hydatidosis were detected in 6 sera (3.11 %) among 193 samples. Results showed two male and four female horses were sero-positive against hydatidosis. In conclusion, present study shows that antibodies against hydatidosis have been detected in Iran equine population. Therefore, it seems that Iranian horse clubs should improve their management and health levels to increase their proficiencies.

“…Although abattoir surveys have limitations, they are an economical way of gathering information on livestock disease. Also, a feedback from the slaughterhouse to the individual farm is of great value in the field of preventive medicine (Azami et al 2013).…”

A retrospective survey of liver flukes in livestock based on abattoir data in Kermanshah, west of Iran

A retrospective study was carried from 2008 to 2013 to estimate the prevalence of liver flukes in ruminants slaughtered at the abattoir of Kermanshah province, west of Iran. A total of 663,633 animals slaughtered in the 5-year period and totally 1.95 % of livers were condemned due to liver flukes. Fasciolosis were responsible for 0.8, 0.7 and 1.5 % of liver condemnations, whereas 1, 0.8 and 1 % of liver were condemned because of Dicrocoelium dendriticum infection in the sheep, goats and cattle, respectively. A significant difference in the prevalence of liver flukes were observed among studied animals (p \ 0.001) and the highest and lowest prevalence were detected in cattle and goats, respectively. Data showed significant seasonal pattern for distomatosis in sheep and goat (p \ 0.001). Liver condemnations due to fasciolosis were prevalent in sheep and goats and cattle slaughtered during winter, summer and autumn, respectively, whereas dicrocoeliosis were common in autumn season for sheep and cattle and in winter for goats. This survey provides baseline data for the future monitoring of these potentially important parasitic infections in the region.
