early diagnosis of human hydatid disease by detecting the specific antibodies in patients’ sera is considered as an important step in treatment of infection. but the diagnostic efficiencies of assays greatly depend on the characteristics of antigen that is used and various conditions in performance. in present study, we tried to standardize an indirect haemagglutination test, using antigen b fo...

Hydatid antigen was demonstrated for the first time in the urine of patients with hydatid disease by countercurrent immunoelectrophoresis (CIEP). The antigen was detected in the concentrated urine of 7 of 16 (43.75% positive) patients with surgically confirmed hydatid disease, 4 of 10 (40% positive) patients with ultrasound-proven hydatid disease (daughter cysts or prominent septation and hydat...

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...

○ INTRODUCTION Hydatidosis is a silent, cyclozoonotic and oldest infection of man and domestic animals and is caused by larvae of the cestode, Echinococcus (Bhatia and Pathak, 1990). The infected human beings and animals loose their normal functional capacities leading to huge economic losses. The diagnosis of hydatid disease is based on clinical, radiological, microscopical and immunological m...

background: echinococcosis is a parasitic disease with worldwide distribution which is caused by the tapeworms echinococcus granulosus . diagnosis of the disease relies on imaging techniques, but the techniques are not able to differentiate the cyst from benign or malignant tumors; hence, appropriate serologic methods are required for the differential diagnosis of the infection. materials and m...

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...

Background: Hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of Echinococcus granulosus. Diagnosis of hydatidosis is still an unresolved problem. Serological tests using crude antigens for diagnosis of E. granulosus are sensi-tive, however their specificity are not satisfactory. Therefore, WHO recommended spe-cific serological methods using specific antigens,...

background: cystic echinococcosis caused by the metacestode of echinococcus granulosus is a major problem in both humans and domestic animals health. there-fore, a standardized and approachable diagnostic tool (rapid tests) for the serodiag-nosis of cystic echinococcosis (ce) is still needed. methods: in the present work, antigen b labeled with gold nanoparticles was used to detect antibodies a...

Diagnosis of hydatid disease in humans relies on the detection of specific antibodies against antigens of the metacestode from Echinococcus granulosus. The specificity and sensitivity of current immunological techniques based on specific serum IgG rely on the way antigens are purified. We used Western immunoblotting to detect specific IgG, IgE, and IgA antibodies in serum from patients with hyd...
