title: Evidence for recombination between two different immunological types of foot-and-mouth disease virus.
abstract: Recombination was observed between temperature-sensitive (ts) mutants of two immunological types of foot-and-mouth disease virus which were distinguishable by two marker characteristics in addition to their antigenic type. Putative ts+ recombinants were isolated and the segregation patterns of their marker characteristics examined. The results are discussed in terms of the origin of new sub-type strains.
