Genetic Characterization of Genogroup I Norovirus in Outbreaks of Gastroenteritis

Norovirus genogroup II gastroenteritis in hospitalized children in South India.

The distribution of norovirus (NoV) genogroup II in children < 5 years of age admitted to a south Indian hospital with diarrhea was investigated. Viral RNA extracted from 282 stool samples were screened for NoV GII and positive amplicons sequenced. Twenty-eight (9.9%) had NoV GII infection with a median age of 6 months, with more severe episodes of diarrhea among infected (median Vesikari score...

Molecular Evolution of the Capsid Gene in Norovirus Genogroup I

We studied the molecular evolution of the capsid gene in all genotypes (genotypes 1-9) of human norovirus (NoV) genogroup I. The evolutionary time scale and rate were estimated by the Bayesian Markov chain Monte Carlo (MCMC) method. We also performed selective pressure analysis and B-cell linear epitope prediction in the deduced NoV GI capsid protein. Furthermore, we analysed the effective popu...

بررسی فراوانی عفونت نوروویروسی و ژنوگروه غالب آن در کودکان مبتلا به گاستروانتریت حاد مراجعین به دو بیمارستان تخصصی کودکان تهران در 1388-1387

Abstract Background: One of the most important pathogens responsible for acute gastroenteritis is Human Norovirus (NoV), causing >85% of all nonbacterial outbreaks of gastroenteritis reported in Europe. NoVs are members of the Family Caliciviridae. There are three infectious genogroups genogroups I and II are recognized as the major cause of NoVs infections in humans. The aim of this study w...

Molecular Characteristics of Noroviruses Genogroup I and Genogroup II Detected in Patients With Acute Gastroenteritis

Noroviruses are the leading cause of epidemic gastroenteritis, including foodborne outbreak, in Korea. The prevalence of human noroviruses was studied in diarrheal stool samples of patients with acute gastroenteritis by conventional duplex reverse transcription (RT)-PCR. Diarrheal stool samples were collected from 1,685 patients from the local hospitals in Seoul. The prevalence of the norovirus...
