Characterization of foot-and-mouth disease virus types Ο and Asia 1 RNA.

Poly (A) RNA was isolated from foot-and-mouth disease virus-infected cells by oligo (dT)-cellulose chromatography. One-dimensional oligonucleotide mapping of virusinduced poly (A) RNA indicated major differences between virus types Ο and Asia 1. Base composition analysis of virus-induced RNA showed no significant differences between types O and Asia 1.
