Abstract
Reovirus type 3 variants with mutations in the major neutralization domain of the σ1 protein have attenuated neurovirulence and restricted neurotropism. We devised a variation of the rapid RNA sequencing technique to facilitate the analysis of double-stranded RNA. We sequenced the S1 double-stranded RNA segment, which encodes the σ1 protein, of five attenuated reovirus type 3 variants. Four of the variants have changes in codon 419, and a fifth variant has a change at codon 340, all of which resulted in amino acid substitutions in the σ1 protein. We identified two sites on the reovirus type 3 σ1 protein that play a critical role in neurovirulence.
