Attenuation of Venezuelan equine encephalitis virus strain TC-83 is encoded by the 5'-noncoding region and the E2 envelope glycoprotein
1 Mar 1993
Abstract excerpt
The virulent Trinidad donkey (TRD) strain of Venezuelan equine encephalitis (VEE) virus and its live attenuated vaccine derivative, TC-83 virus, have different neurovirulence characteristics. A full-length cDNA clone of the TC-83 virus genome was constructed behind the bacteriophage T7 promoter in the polylinker of plasmid pUC18. To identify the genomic determinants of TC-83 virus attenuation, TRD virus-specific...
