title: [Antigenic structure of foot-and-mouth virus. IV. Synthesis and immunogenic properties of new fragments of the VP1 protein of food-and-mouth virus strain A22].
abstract: A synthesis of new fragments of VP1 protein with the specificity of A22 strain of foot-and-mouth disease virus is described. Immunization with the free 136-152 peptide and KLH-conjugates of the peptides 136-152 and 197-213 induced 60-80% protection of guinea pigs against challenge with the A22 virus. Synthetic peptides corresponding to the 10-24, 50-69 and 175-189 sequences of VP1 did not show any protective activity. We have found that uncoupled peptides 175-189 and 197-213 are able to induce antipeptide antibodies. However, these antibodies did not possess any neutralizing activity. Immunization of animals with the mixture of (136-152)O1K and (175-189)A22 has led to inhibition of the immune response to the (136-152)O1K fragment.
