Molecular evolution of the VP7 gene of Japanese G2 rotaviruses before vaccine introduction

Molecular evolution of the VP7 gene of Japanese G2 rotaviruses before vaccine introduction Changes in the prevalence of G2 rotavirus after vaccine introduction are an important issue. However, such changes in a given country should be interpreted in the global context over time. We determined 35 Japanese G2 sequences and compared them with 508 globally collected G2 sequences. The D96N substitution, a substitution known to be associated with an abrupt increase in G2 strains and antigenic changes, emerged in those strains that formed a nascent lineage outside of the currently predominant lineage (sublineage IVa). Further studies are warranted to monitor the potential of their global spread, since they also appeared in Europe and Australia. Archives of Virology Springer Journals
