[Classification of strains of foot-and-mouth disease virus according to the relationship-dominance model for a better understanding of the concept of serologic and immunologic subtype].

The homologous and heterologous serological titers of a specific serum can be integrated in a bidimensional system which characterizes the criteria of relationship and dominace. This bidimensional classification specifies more precisely the serological properties of each strain compared with the others (taxonomic purpose) and allows eventual guidance in the choice of vaccinal strains (epizootiologic and prophylactic purposes).
