“…In the current study, the phylogenetic analysis revealed differences in the VP7 genetic lineages among Korean G1 strains. All Korean G1 strains circulating in recent years [Moon et al, 2007;Le et al, 2008] grouped into VP7 genetic lineage I. A Korean G1 strain (Kor-64), which was detected from an infant with diarrhea in 1988 [Jin et al, 1996], belonged to VP7 genetic lineage IV, providing evidence of genetic variation over the years.…”

“…Until 1997, G1 was the most prevalent strain, regardless of geographic area or season [Kim et al, 1990[Kim et al, , 1999Kim, 1993;Seo and Sim, 2000]. Since 1997, the predominant G type strain shifted to G4 Song et al, 2003;Kang et al, 2005], to G2 Moon et al, 2007], and then to G9 . More recently, our data from a 2-year investigation indicated that the G1 strain has become the most common [Le et al, 2008].…”

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 electropherotype, 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[8]-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.

“…The finding that G-type prevalence fluctuated markedly, depending on the year studied, confirms previous reports. 15,16 Although largely recognized as a cause of asymptomatic infection among newborns, P [6] genotype rotaviruses are emerging as a frequent cause of diar- rhea among children. 17,18 This strain was detected for the first time in Lanzhou in 1.4% of stool samples in this study.…”

“…Other combinations, such as P [6] or P [9] with any G type, circulated with low frequency, while they were dominant in some areas of the world during some seasons. [14][15][16][17][18][19][20] As P [6] and P [9] are associated with infections in pigs and cats, these genogroups may arise from the interspecies transmission or animal-human reassortments. 21 Our findings indicated the diversity of circulating rotavirus strains from 2001 to 2005 in Shanghai.…”
