[Antigenic structure of the foot-and-mouth virus. VI. Functional segments of the immunodominant region of the VP1 protein of foot-and-mouth virus strains O1K and A22].

B- and T-epitopes have been localized within the protective fragments of VP1 protein, viz., 136-152 of the O1K strain and 135-159 of the A22 strain of the foot-and-mouth disease virus (FMDV). Antibodies eliciting after immunization of various animals with the 135-159 A22 peptide are directed to different sites of the peptide.
