Cloning and expression of a novel synthetic gene containing VP1 and 3A in Bacillus subtilis as a vaccine candidate against foot-and-mouth disease virus.

In this study the bioinformatics characteristics of VP1 [141-160 and 23-42] and 3A [21-35] of Iranian serotypes O, A and Asia 1 was obtained using on-line predicting software. Then the sequence VP1 [141-160]-GS-VP1 [23-42]-GS-3A [21-35]-GS were codon-optimized and cloned onpHT43shuttle vector and finally expressed in Bacillus subtilis WB600 strain. We could predict VP1 [141-160] as a B cell epitope, VP1 [23-42] as a CTL epitope and 3A [21-35] as a Th cell epitope. The 20KD recombinant protein expressed by Bacillus subtilis were detected by SDS-PAGE. The results showed that this recombinant protein had epitope characteristics and it could be useful as a vaccine candidate to control all serotypes of FMD in Iran.
