title: [Subtypes of foot-and-mouth disease virus type A. Genetic markers of clones obtained from 4 strains isolated in Argentina between 1961 and 1970].
abstract: The results obtained studying the genetic markers g, t and rtc of different clones of subtypes of foot-and-mouth disease virus type A are presented in this paper. The subtypes were isolated during outbreaks of foot and mouth disease in Argentine. No significative differences among the subtypes were observed with the t marker. For the other markers, the results seem to indicate a gradual change related with the serological variation. Because of their sensibility to guanidine hidrochloride, it is possible to conclude that the studied clones do not belong to the so called European strains.
