Detection of antibodies against norovirus genogroup GIV in carnivores.
Noroviruses (NoVs) resembling human NoV genotype GIV (Alphatron-like) have recently been detected in carnivores. By using an enzyme-linked immunosorbent assay based on baculovirus-expressed capsid protein VP1 of lion strain GGIV.2/Pistoia/387/06/ITA, NoV-specific antibodies were detected in cats (16.11%) and dogs (4.8%), demonstrating that these animals are exposed to infections caused by NoVs.
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...
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 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 کاملIdentification of Genogroup I and Genogroup II broadly reactive epitopes on the norovirus capsid.
Norwalk virus, a member of the family Caliciviridae, is an important cause of acute epidemic nonbacterial gastroenteritis. Norwalk and related viruses are classified in a separate genus of Caliciviridae called Norovirus, which is comprised of at least three genogroups based on sequence differences. Many of the currently available immunologic reagents used to study these viruses are type specifi...
