Norovirus Recombination in ORF1/ORF2 Overlap
Norovirus (NoV) genogroups I and II (GI and GII) are now recognized as the predominant worldwide cause of outbreaks of acute gastroenteritis in humans. Three recombinant NoV GII isolates were identified and characterized, 2 of which are unrelated to any previously published recombinant NoV. Using data from the current study, published sequences, database searches, and molecular techniques, we i...
متن کاملEvidence of recombination in the norovirus capsid gene.
Noroviruses are single-stranded RNA viruses with high genomic variability. They have emerged in the last decade as a major cause of acute gastroenteritis. It remains so far unclear whether norovirus evolution is driven by sequence mutation and/or recombination. In this study, we have assessed the occurrence of recombination in the norovirus capsid gene. For this purpose, 69 complete capsid sequ...
متن کاملThe importance of intergenic recombination in norovirus GII.3 evolution.
Norovirus genotype II.3 (GII.3) strains are a major cause of sporadic gastroenteritis. Intergenic recombination between the capsid and RNA-dependent RNA polymerase (RdRp) genes is common and results in the acquisition of an alternative RdRp genotype. This study aimed to explore the evolution of the GII.3 capsid gene, focusing on the influence of intergenic recombination. The capsid genes from s...
متن کاملEvidence for recombination between pandemic GII.4 norovirus strains New Orleans 2009 and Sydney 2012.
During 2012, a novel pandemic GII.4 norovirus variant, Sydney 2012, emerged worldwide. A signature of the variant was a GII.Pe ORF1, in association with GII.4 Apeldoorn 2008-like ORF2-ORF3 genes. We report the detection of recombinant GII.4 Sydney 2012 strains, possessing the ORF1 gene of the former pandemic variant New Orleans 2009.
متن کاملEpidemiology of Rotavirus-Norovirus Co-Infection and Determination of Norovirus Genogrouping among Children with Acute Gastroenteritis in Tehran, Iran
Background: Enteric viruses, particularly human rotavirus and norovirus, have been shown to replace bacteria and parasites, as the most common pathogens responsible for acute diarrhea. However, there are still few epidemiological data on the simultaneous occurrence of these viruses in Iran. In this regard, the aim of this study was to assess the useful epidemiological data on the gastroenteriti...
