چکیده

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 methods: in this investigation, different sheep hydatid cyst antigens probed with thirty sera of patients with hydatid cyst and also thirty human normal sera using western immunoblotting technique. considering results of surgery as gold standard, sensitivity and specificity of western blotting was estimated. results: sera of 29, 26, and 16 patients with hydatid cyst reacted with specific bands of hydatid cyst fluid (hcf), protoscolex crude antigen, and cyst wall crude antigen, respectively. however, none of the normal human sera reacted with those specific bands. conclusion: a 20 kda band of sheep hcf is an appropriate antigen for serodiagnosis of hydatid cyst infection.

Immunological follow-up of hydatid cyst cases.

Hydatid disease is caused by Echinococcus granulosus. In this study, we aimed to investigate the benefit of monitoring cases with hydatid cyst by means of immune components in patients in a long-term follow-up after surgery. Eighty-four preoperative and postoperative serum samples from 14 cases undergoing surgery for hydatid disease were evaluated in terms of immune parameters, such as total an...

Antibody response to glycan antigens of hydatid cyst fluid, laminated layer and protoscolex of Echinococcus granulosus

Background: Hydatid disease is characterized by long-term growth of hydatid cysts in the human. The glycan antigens have an important role in the immunology of hydatid cyst. In this study immunological reaction of host sera to different glycan antigens of the cyst, has been investigated. Methods: The antibody responses were tested to glycoprotein and glycolipid of the laminated layer (LL), c...

Analysis of western blotting (immunoblotting) technique in diagnosis of congenital syphilis.

The diagnosis of congenital syphilis in apparently healthy infants continues to be problematic. Immunoglobulin M antibodies specific for a subset of Treponema pallidum antigens have been detected by Western blotting (immunoblotting). In the present study we investigated the sensitivity and specificity of this method. We tested 26 infants aged 0 to 4 months who fulfilled the accepted criteria fo...
