Abstract

A set of monoclonal antibodies was used to isolate nonneutralizable foot-and-mouth disease virus variants, and the RNAs of the variants were sequenced. Cross-neutralization studies and mapping of the amino acid changes indicated two major antigenic sites. The first site was trypsin sensitive and included the VP1 140 to 160 sequence. The second site was trypsin insensitive and included mainly VP3 residues. Two minor sites were located near VP1 169 and on the C terminus of VP1. Comparison with poliovirus type 1 and human rhinovirus 14 showed a similarity in the immunogenicity of comparable sites on the viruses.

摘要

使用一组单克隆抗体分离不可中和的口蹄疫病毒变体,并对这些变体的RNA进行测序。交叉中和研究和氨基酸变化图谱显示了两个主要抗原位点。第一个位点对胰蛋白酶敏感,包括VP1的140至160序列。第二个位点对胰蛋白酶不敏感,主要包括VP3残基。两个次要位点位于VP1 169附近和VP1的C末端。与1型脊髓灰质炎病毒和人鼻病毒14的比较表明,这些病毒上可比位点的免疫原性具有相似性。
