Abstract

Unusual DS-1-like intergenogroup reassortant rotaviruses with a bovine-like G8 genotype (DS-1-like G8P [8] rotaviruses) have emerged and rapidly spread in several countries. In this study, the nucleotide sequences of seven human rotavirus G8P [8] strains in 2017 and 2019 in Japan were determined using viral metagenomics. Its genomic constellation (VP7-VP4-VP6-VP1-VP2-VP3-NSP1-NSP2-NSP3-NSP4-NSP5 genes) was defined as G8-P [8]-I2-R2-C2-M2-A2-N2-T2-E2-H2. Our genetic analysis revealed that the Japanese G8P [8] rotavirus strains in 2017 and 2019 were classified into the same lineages G8-5 and P [8]-3, but they were phylogenetically located on separate branches and belonged to distinct clusters. Our study is the first attempt to investigate the evolution of emerging rotavirus G8P [8] in Japan.
