Immunodiagnosis of Echinococcus granulosus infection in dogs by counter immunoelectrophoresis (CIEP).

The present study was undertaken for the detection of Echinococcus granulosus specific antibodies in dogs by counter immunoelectrophoresis (CIEP) with two different antigens viz., somatic and excretory secretory (E/S) antigens of E. granulosus adult worm. Totally 100 field serum samples were examined for the detection of anti-E. granulosus antibodies using somatic and E/S antigens of E. granulosus. The CIEP can able detect nine and eight E. granulosus specific antibodies with E/S and somatic antigen of E. granulosus, respectively. The sensitivity was found to be 90 and 80 % and the specificity was 100 % with E/S and somatic antigen of E. granulosus, respectively.
