Objectives: The purpose of this study was to examine the diversity of the G and P types of human rotavirus strains isolated in South Korea during 2000 to 2004. Methods: We selected 38 Group A rotavirus isolates among 652 fecal samples, which were collected from infants and children < 5 years of age with acute gastroenteritis or diarrhea admitted in 8 hospitals representative of five provinces of South Korea between 2000 and 2004. Rotavirus P- and G-genotypes were determined by nucleotide sequencing and phylogenetic analysis was performed. Results: One G1P consisted G1-Id-P-V; one G1P consisted G1-Id-P-Ia; nine G1P consisted G1-Ib-P-Ia (n=3), G1-Ic-P-Ia (n=1), and G1-Id-P-Ia (n=5); 13 G2P consisted G2-V-P-V; two G3P consisted G3-IIId-P-V; five G3P consisted G3-IIId-P-Ia; four G4P consisted G4-Ie-P-Ia; two G4P consisted G4-Ie-P-II; one G9P consisted G9. -III-P-Ia. Conclusions: A considerable amount of rotavirus genotypic diversity was detected in South Korea from 2000 to 2004. These findings are important to develop the effective vaccines and to undertake epidemiologic studies. © 2012.
