a Detection of FMDV specific antibody response in serum analyzed by competition ELISA assay at day 42 post-immunization. The PI (%) means the percent inhibition. [PI = 100–100 × (OD₄₅₀ of sample serum/OD₄₅₀ of negative control)]. Negative and positive controls were satisfied with standard recommending of manufacturer manual. Each symbol represents the value for individual animals. Horizontal lines describe the mean value for each group of animals. **: P < 0.01; ***: P < 0.001, one way ANOVA. b Antibody response to each peptide in 5BT in serum analyzed by ELISA assay at day 42 post-immunization. Antibody titers were expressed as the reciprocal log10 of the last dilution calculated by interpolation to give an absorbance. Error bars represent standard deviation
