چکیده مقاله:
Foot-and-mouth disease is an extremely infectious and occasionally fatal viral disease with a rapid onset and a short course that affects cloven-hoofed animals and results in considerable financial losses. Today, Foot-and-mouth disease is controlled by traditional inactivated vaccines. Due to the short duration of immunity, a study was conducted for proteins of the virus as well as obtaining immunodominant proteins to design more efficient vaccines against Foot-and-mouth disease virus. This research aims to study the profile of Foot-and-mouth disease virus protein by electrophoresis and identification of the immunodominant proteins. The purified Foot-and-mouth disease virus was purchased then the protein concentration of that solution was measured by Lowry method. SDS-PAGE was done to achieve the protein profiles of the virus and immunization of ۵ guinea pigs was done, then blood samples were taken for obtaining serum. Finally, serology tests; double immunodiffusion, ELISA, and western blotting were used to evaluate antigen response to antibodies (antigenic immunization). The protein concentration was ۳.۵ mg/ml. In SDS-PAGE with ۱۰% gel, the protein profile of the virus was observed. After immunization, by conducting double immunodiffusion tests, the sediment lines between the serum antibody and the antigen of the virus were formed. Also, The ELISA test showed that the antibodies were formed against the antigens. In the western blot test, two immunodominant proteins of the FMD virus were obtained. According to the results, the immunodominant proteins of the FMD virus were determined. These proteins can be used in immunological diagnostic methods and also novel vaccines.
