Purpose: Efficacy of the new rotavirus vaccines (Rotarix, RotaTeq) recently developed can be affected by the rotavirus genotypes prevalent in communities. We performed this study to identify the recent distribution of rotavirus genotypes prevalent in Jeju.

Methods: Genotyping of human rotaviruses was performed using 81 samples collected from 154 inpatients and outpatients with rotavirus gastroenteritis at Cheju National University Hospital between July 2005 and June 2006. All six (1, 2, 3, 4, 8, 9) G serotypes were identified by amplification of segments of the gene for VP7 using the reverse transcription-polymerase reaction (RT- PCR).

Results: The results of RT-PCR for 81 samples were all positive. G typing of the VP7 protein showed that G1 was the most dominant circulating genotype (65.5%) followed by G2 (14.8%), G3 (13.6%), G8 (1.2%), G9 (1.2%), G4 (0%), and a combination of G1/G3 (3.7%).

Conclusion: This distribution of rotavirus VP7 genotypes in Jeju is different from that in other domestic areas; the most dominant circulating genotype was G1. (Korean J Pediatr Gastroenterol Nutr 2006; 9: 147¢¦152)
