Fasciolosis is a disease caused by liver fluck of the genus of fasciola. Diagnosis of fasciolosis has been challenging for a long period due to low sensitivity of the coprological diagnostic method. In this study, an in-house Dot-ELISA method; using excretion–secretory (ES Ag) and Crude (Cr Ag) antigens of fasciola was described for diagnosis of fasciolosis in cattle. For this purpose, the sera specimens of slaughtered cattle were taken and examined for fasciola infection. Sera from two groups of cattle, one infected with fasciola (n = 60) and the other non-infected with fasciola (n = 60), were used in the Dot- ELISA test. All sera were tested and evaluated. Except specificity, other parameters such as, sensitivity, accuracy, positive and negative predictive values of Dot- ELISA with ES Ag were better than those of Dot- ELISA with Cr Ag. In conclusion, excretory–secretory antigen dependent Dot-ELISA can be used as a reliable sero-diagnostic test for fasciola infection in cattle.

Fasciolosis and dicrocoeliosis are endemic parasitic diseases in Middle East especially Iran, which making significant economic problems. This retrospective survey has been done to evaluate contamination rate of slaughtered animals with fasciolosis and dicrocoeliosis at Meisam abattoir, in Tehran, Iran. In this survey, prevalence rate of fasciolosis and dicrocoeliosis in slaughtered animals in a three-year period (2005-2008) has been analyzed. The prevalence rates of fasciolosis and dicrocoeliosis in cattle were 2.20 % and 2.5 %, and the rates in sheep were 2.01 % and 5.83 %, respectively. The average annual direct economic loss incurred as a result of condemnation of ovine and bovine infected livers due to fasciolosis and dicrocoeliosis were estimated as high as 227,907 USD. The results of current survey revealed the rate of dicrocoeliosis is higher than fasciolosis. Our work proved that the highest frequency rate of the fasciolosis and dicrocoeliosis in cattle was in summer and spring, respectively. Whereas winter and autumn had the highest prevalence rate of fasciolosis and dicrocoeliosis in sheep.
