Molecular characterization of norovirus GII strains identified in Albania.
Noroviruses (NoVs) are considered as the leading cause of diarrheal diseases in all groups of age. In the last decade the number of NoV outbreaks worldwide is increasing. Data published by the systems of NoV surveillance show the GII.4 strain as the human predominant genotype circulating worldwide and new genetic variants of GII.4 were associated with epidemic events. In Albania the economy tra...
متن کاملMarked genomic diversity of norovirus genogroup I strains in a waterborne outbreak.
Marked norovirus (NoV) diversity was detected in patient samples from a large community outbreak of gastroenteritis with waterborne epidemiology affecting approximately 2,400 people. NoV was detected in 33 of 50 patient samples examined by group-specific real-time reverse transcription-PCR. NoV genotype I (GI) strains predominated in 31 patients, with mixed GI infections occurring in 5 of these...
متن کاملNorovirus 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...
متن کاملMolecular 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...
متن کاملSeroprevalence of Norovirus Genogroup IV Antibodies among Humans, Italy, 2010–2011
Noroviruses (NoVs) of genogroup IV (GIV) (Alphatron-like) cause infections in humans and in carnivorous animals such as dogs and cats. We screened an age-stratified collection of serum samples from 535 humans in Italy, using virus-like particles of genotypes GIV.1, circulating in humans, and GIV.2, identified in animals, in ELISA, in order to investigate the prevalence of GIV NoV-specific IgG a...
