title: Evaluation of the antigenic variation within type-A foot and mouth disease virus isolates from Asia.
abstract: The serological interrelationships among 17 type A FMD virus strains from eight Asian countries were studied by the two-dimensional microneutralization test. Complex direct and indirect relationships were observed. Overall, however, the virus strains studied could be classified as belonging to the A22 group on the basis of r value differentiation at P less than 0.01.
