Abstract

Variants of type A FMD virus from the Eastern Mediterranean region over the years 1964–72 have been shown to belong to a group distinct from the Western European strains as represented by A5 Westerwald. This group appears to derive from the A22 strain first recognized in 1964 and indicates the possibility of new strains supplanting old in the field.
