Predominance of DS-1-like G8P[8] rotavirus reassortant strains in children hospitalized with acute gastroenteritis in Thailand, 2018-2020.

Rotavirus A (RVA) is an important cause of acute gastroenteritis (AGE) in children. This study aims to investigate the molecular epidemiology of RVA in children hospitalized with AGE in Chiang Rai, Thailand in 2018-2020 by reverse transcription polymerase chain reaction. Of 302 samples, RVA was detected in 11.

Emergence of G9P[8] rotaviruses in children with acute gastroenteritis in Thailand, 2015-2016.

Human group A rotavirus is a major contagious virus causing gastroenteritis in children. Molecular epidemiological study of group A rotavirus infections in hospitalized children was performed by multiplex RT-PCR during 2015-2016 in Chiang Rai, Thailand. G- and P-genotypes of positive rotavirus samples were further analyzed by one-step and two-step multiplex RT-PCR methods.

Molecular epidemiology of norovirus associated with gastroenteritis and emergence of norovirus GII.4 variant 2012 in Japanese pediatric patients.

In late 2012, an outbreak of acute gastroenteritis due to norovirus variant Sydney_2012 occurred and have been reported from many counties. In this study, we described surveillance study of the incidence of norovirus infections among Japanese pediatric patients in association with gastroenteritis and investigated the antigenic change of the new variant Sydney_2012 circulated in Japanese populations. A total of 2381 fecal specimens collected from children with acute gastroenteritis in Hokkaido, Tokyo, Shizuoka, Kyoto, Osaka, and Saga from 2009 to 2013 were examined for norovirus and further analyzed molecularly.

Genetic analysis and homology modeling of capsid protein of norovirus GII.14.

In this study, a more detailed genetic characterization of the VP1 capsid protein of uncommon norovirus (NoV) GII.14 strains reported previously in Japan and China was performed using sequence analyses and homology modeling technique. The result of genetic comparison with the M7 prototype strain of GII.

Emergence of norovirus GII/4 2006a and 2006b variants in hospitalized children with acute gastroenteritis in Thailand.

Background: Norovirus (NoV) is recognized as a significant cause of acute gastroenteritis in infants and young children worldwide. This study investigated the prevalence of NoV infection in hospitalized children with gastroenteritis in Chiang Mai, Thailand in 2006.

Methods: A total of 156 fecal specimens were collected from children with diarrhea admitted to McCormick Hospital in 2006.
