The Prevalence and Distribution of the P and G Genotypes of a Group A Rotavirus Detected in Acute Gastroenteritis Patients from Incheon

Rotavirus is the main cause of severe diarrhea in infants and young children of the world. However, the frequency of genetic alterations makes it hard to control the prophylaxis. Therefore, continuous monitoring of the rotavirus’s genetic change is inevitable to prevent disease prevalence and is useful in inventing an efficient vaccine. From January 2005 to December 2010, we investigated 11,607 stool samples of acute gastroenteritis patients in the Incheon metropolitan area. About 13.18 % (1,530 stool samples) of all samples had a positive reaction against rotavirus using an antigen capture en-zyme-linked immunosorbent assay (ELISA). Then, the 160 stool samples were searched for subtypes of group A rotavirus by using a reverse transcription polymerase chain reaction (RT-PCR) and a nest-ed multiplex RCR. In P sub-typing, P8 (56.3%) was an extremely prevalent genotype, followed by P6 (21.3%), and P1A (10.0%). G1 (39.4%) was most widespread in the G subtype, followed by G4 (25.0%) and G3 (18.8%). G1P8 (35.5%) was the most common G and P subtype combination, followed by G4P6 (19.3%) and G3P8 (13.1%). These results might be useful data for understanding the epidemiologica
