Human and camel cystic echinococcosis - a polyclonal antibody-based sandwich ELISA for its serodiagnosis with molecular identification.

ABSTRACT: Cystic echinococcosis (CE) is an emergent neglected disease affecting human and animals in Egypt with a wide distribution and incidence. This study aimed to evaluate the use of a polyclonal antibody-based sandwich ELISA in the detection of Echinococcus granulosus antigen in human and camel sera. Hydatid cyst protoscoleces antigen (PsAg) was isolated from hydatid cysts collected from naturally infected camel livers and lungs. PsAg was used for immunization of rabbits to raise IgG polyclonal antibodies (IgG PsAb). IgG PsAb were then precipitated, purified using Protein-A Sepharose gel and labeled with horseradish peroxidase enzyme. We assayed the purity of the IgG PsAb, and the two prepared E. granulosus antigens CPsAg from camel cysts and HPsAg from human cysts by Sodium dodecyl-sulfate pol
