Abstract
Norovirus (NoV) is a major cause of nonbacterial acute gastroenteritis worldwide. New strains emerge partly due to viral recombination. In Thailand, there is a lack of data on NoV recombinants among clinical isolates. We screened stool samples from pediatric diarrheal patients for norovirus by RT-PCR and found GII.4 to be the most prevalent genotype. Phylogenetic and SimPlot analyses detected seven intra-genogroup recombinant strains: three GII.21/GII.3, two GII.12/GII.3, and two GII.12/GII.1 recombinants. Maximum chi-square analysis indicated that all had similar breakpoints near the ORF1/ORF2 junction (p < 0.001), either slightly upstream within the C-terminus of RdRp or downstream within the N-terminal domain of VP1.Entities:
