Abstract

Bioterrorism, the deliberate release of microbial agents or other agents which can cause various illness or death in living things. Egg yolk immunoglobulin (IgY) was prepared against cholera, by immunizing hens with formalin killed V. cholera serotype ogawa. Booster injections of the antigen were subsequently given to the chicken. Using polyethylene glycol and ammonium sulfate precipitation method the antibodies produced were purified. Further Diethylaminoethyl (DEAE) cellulose ion-exchange column chromatography was also carried out. From the egg yolk the IgY fraction was separated and each step of the separation was viewed on Sodium Dodecyl Sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). The specificity and reactivity of V. cholera was confirmed by ELISA method. The highest titer of antibody at the dilution of 1:10000 was observed at the 21st week of vaccination and the serum agglutination test also showed a positive result. So it can be suggested that anti- V. cholera produced had a high specificity towards V. cholera O1. As a result anti- V. cholerae IgY may be utilized as preventive agent against Cholera infection.
