Isolation and characterization of a diagnostic polysaccharide antigen from larval Echinococcus multilocularis.
A diagnostic antigen, C-antigen, was evaluated in serodiagnosis of alveolar hydatid disease by Western blotting. The C-antigen migrated diffusely to the region of 30-35 kDa in 8% polyacrylamide-SDS gel electrophoresis. We isolated this antigen from a crude metacestode extract by a simple method of phenol/chloroform extraction. The isolated antigen was resistant to boiling, proteolysis and acid ...
متن کاملMolecular cloning of a vaccine antigen against infection with the larval stage of Echinococcus multilocularis.
Alveolar and cystic hydatidosis are caused by infection with the larval stages of Echinococcus multilocularis and Echinococcus granulosus, respectively. A host-protective antigen has been identified in E. granulosus. Here we identify the presence of a closely related protein in E. multilocularis, characterize and express a cDNA encoding the antigen (designated EM95), determine the structure of ...
متن کاملIsolation 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 major Echinococcus multilocularis antigen is a mucin-type glycoprotein.
The metacestode of Echinococcus multilocularis is surrounded by a carbohydrate-rich laminated layer, which plays a key role in the establishment of the infection in the mammalian host. A major component of the laminated layer is an antigen referred to as Em2(G11). This highly species-specific antigen has been used for serodiagnoses of alveolar echinococcosis and is suggested to contain carbohyd...
متن کاملEchinococcus multilocularis in Estonia
To the Editor: Alveolar echinoco-ccosis (AE) caused by Echinococcus multilocularis is one of the most important emerging zoonosis in Europe. The fatality rate is >90% in untreated patients (1). In Europe, the distribution range of the zoonotic tapeworm E. multilocularis has expanded over the last few decades, and the parasite attracts increasing awareness as a public health issue (2–5). In 2003...
