Evidence for a mouse pathogenicity locus in certain temperature-sensitive mutants of foot-and-mouth disease virus.

RESUMO

Serial tissue culture passaging of three foot-and-mouth disease temperature-sensitive mutants demonstrated the stability of their temperature sensitivity and mouse avirulence characteristics. Recovery of mouse-virulent temperature-sensitive viruses after passage of the mutants in mice suggested that these were not covariant expressions of the same locus, but were under the control of different genes.
