study of different immunogenic antigens of echinococcus granulosus on immunization against hydatid cyst in sheep

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...

Antibody response against hydatid fluid, protoscolex and whole body of Echinococcus granulosus antigens in lambs

In this study, the immunogenicity of three types of antigens (hydatid fluid, protoscolices and whole body of E. granulosus) was investigated in lambs by ELISA. Sixteen 4–6-month-old lambs of mixed sexes were divided into 4 groups of 4 lambs (three immunized and one control group). Twelve lambs as immunized groups received 2 mg of hydatid fluid, protoscolices and whole body of E. granulosus ant...

Chemical Composition of Hydatid Cyst Fluid of Echinococcus granulosus

Immunization of sheep against Echinococcus granulosus with protoscolex tegumental surface antigens

AIM Cystic echinococcosis (CE) has potential economic effects to both animal products and human health. A vaccine to protect livestock against CE can be effective in reducing economic costs and increasing the livestock products. Protoscolex tegumental surface antigens (PSTSA) used to induce the production of specific antibodies against Echinococcus granulosus in sheep. The tegumental antigens w...

Immunization of dog with proteins under 30 kDa molecular weight of hydatid cyst fluid and protoscoleces of Echinococcus granulosus

The aim of the present study was to assess the immunogenicity of under 30kDa molecular weight proteins of hydatid cyst fluid and protoscoleces in dogs experimentaly Infected with Echinococcus granulosus. Isolation of under 30 kDa proteins performed using Millipore filter. Six dogs were used in three groups: 2 dogs with under 30 kDa proteins of hydatid cyst fluid (Group I); 2 dogs with proteins ...

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...
