- Abstract
- The human rotavirus G1P[8] strain is one of the most common rotaviruses worldwide, including Korea. Six Korean G1P[8] human rotaviruses, isolated using cell culture techniques, were characterized on the basis of sequence differences in VP7, VP4, VP6, and NSP4 genes to elucidate the evolutionary relationships in the community. All strains had a long RNA electro-pherotype, supported by VP6 gene analysis, clearly associated with subgroup II specificity. The phylogenetic analysis of VP7 gene sequences showed that they all clustered into lineage I, as reported for G1 strains in Japan, China, Vietnam, and Thailand. In addition, phylogenetic analysis of the VP4 gene showed that they belong to two distinct lineages, P[8]-II and P[81-III. With respect to the NSP4 gene, all strains belonged to genotype B. An understanding of the ecology and molecular evolution of rotaviruses circulating in the country is very important for the development of vaccines and vaccination strategies. This study provides new information concerning the genetic variability of the rotavirus strain G1P[8] occurring most commonly as a vaccine candidate. Med. Virol. 82:886-896,2070.
