DETECTION OF IGG ANTIBODIES AGAINST HYDATID CYST DISEASE IN HUMAN SERUM BY ELISA

Echinococcosis is a zoonotic infection caused by developmental stages (larvae, hydiatid,metacetodes) of two kinds of tapeworms, Echinococcus granulosus and Echinococcus multilocularis, Sources of infection are final hosts (i.e. dogs for E. granulosus and mainly foxes for E. multilocularis) and food contaminated with parasite eggs. After oral ingestion of parasite eggs by humans (intermediate hosts) and hematogenous distribution inside the host, E. granulosus larvae (oncospheres) begin to vesiculate mainly in the liver and lungs and in other organs. The difficulty and the similarity of clinical symptoms with other diseases, the disease is diagnosed Serological ways including ELISA test.82 serum samples collected from some hospitals in Baghdad randomly. To detect the Human Hydatid Cyst disease non-visible symptoms in humans and used the ELISA test. results showed 18.29% positive case.
