Purification and Immunobiochemical Characterization of Sheep Hydatid Cyst Fluid Antigen
In the present study, sheep crude hydatid cyst fluid antigen (SCHCFA) was prepared by ammonium sulfate precipitation, centrifugation and dialysis. SDS-PAGE of SCHCFA showed seven polypeptides of 72.8 kDa, 66.5 kDa, 60.2 kDa, 41 kDa, 25.1 kDa, 19 kDa and 8 kDa when stained with Coomassie briliant Blue R-250. The initial part of the ascending loop of the first peak (PI) when resolved by gel filtr...
متن کاملClinical evaluation of a complement fixation test using human hydatid cyst fluid antigen for the detection of Echinococcus granulosus antibody
Complement fixation (CF) is a commonly used serodiagnostic test for hydatid disease, especially recommended for the evaluation of cure after surgery or for checking on treatment with antihelminthic drugs (9). However, the absence of an FDA-approved standardized antigen makes it difficult to assess the performance of different CF tests by using published studies. The objectives of this study wer...

Isolation and purification of Echinococcus granulosus antigen B from hydatid cyst fluid using three different methods
Hydatid cyst, the larval stage of cestodes Echinococcus spp., is recognized as a zoonotic infection in the world. The World Health Organization (WHO) has recently classified echinococcosis in a group of neglected tropical diseases.The prevalence of Echinococcus granulosus infection is high in Iran due to the presence of various intermediate hosts in this country. Considering the rising trend of...
متن کاملA NOVEL METHOD OF PURIFICATION OF SPECIFIC HYDATID CYST ANTIGEN
Hydatid cyst fluid has been used as a source of antigen for the serodiagnosis of Echinococcus granulosus infection. Due to cross-reactions with antigens shared by other helminthes, the specific antigen from hydatid cyst fluid was purified by many workers. We used a relatively simple technique for purification of specific antigen from sheep hydatid cyst fluid. Isopycnic ultracentrifugation w...
