Norovirus could spread through SHOPPING TROLLEYS, NHS staff warn

A matron at Swansea Bay University Health Board said people can catch norovirus from surfaces in busy areas like supermarkets and should wash their hands with soap and water to avoid it.

AbstractWe modeled Group A Rotavirus (RVA) and Norovirus genogroup II (GII NoV) transport experiments in standardized (crystal quartz sand and deionized water with adjusted pH and ionic strength) and natural soil matrix-water systems (MWS). On the one hand, in the standardized MWS, Rotavirus and Norovirus showed very similar breakthrough curves (BTCs), showing a removal rate of 2 and 1.7 log10, respectively. From the numerical modeling of the experiment, transport parameters of the same order of magnitude were obtained for both viruses. On the other hand, in the natural MWS, the two viruses show very different BTCs. The No...

Environmental factors contribute to Type 1 diabetes (T1D) susceptibility. The gut microbiome, which includes bacteria, viruses, and fungi, contributes to this environmental influence, and can induce immunological changes. The gut viral component of the microbiome, related to T1D has mostly focused on coxsackieviruses and rotavirus. The role of norovirus, another common enteric virus, in susceptibility to T1D was hitherto unknown. Norovirus is highly infectious and encountered by many children. We studied the mouse norovirus 4 (MNV4), related to human noroviruses, in the Non-obese diabetic (NOD) mouse model, to determine it...

zevic Human noroviruses (NoVs) are a genetically diverse, constantly evolving group of viruses. Here, we studied the effect of NoV pre-existing immunity on the success of NoV vaccinations with genetically close and distant genotypes. A sequential immunization as an alternative approach to multivalent NoV virus-like particles (VLPs) vaccine was investigated. Mice were immunized with NoV GI.3, GII.4-1999, GII.17, and GII.4 Sydney as monovalent VLPs or as a single tetravalent mixture combined with rotavirus VP6-protein. Sequentially immunized mice were primed with a trivalent vaccine candidate (GI.3 + GII.4-1999 + VP6) an...

Publication date: Available online 31 October 2019Source: Meta GeneAuthor(s): Yoshiyuki Suzuki, Maho Nishimura, Tatsuya Inoue, Yuki KobayashiAbstractDue to the progress in the sequencing technology, the number of nucleotide sequences for pathogens deposited in the public databases has been increasing rapidly. Consequently, in the molecular evolutionary analyses of pathogens, it may occasionally be difficult to include all the available sequences and necessary to reduce the number of sequences to accomplish computation within a realistic time frame. Here several methods for reducing the number of sequences were evaluated us...

Abstract In Japan, from 2000 to 2018, for Vibrio parahaemolyticus and Salmonella food poisonings, the annual number of the outbreaks and that of the patients decreased exponentially though the size of the individual outbreaks (the number of patients per outbreak) tended to become larger. For food poisonings caused by Campylobacter, the annual number of the outbreaks increased exponentially while the outbreak size became smaller and the annual number of the patients remained almost unchanged. For food poisoning caused by norovirus, both the number of the outbreaks and that of the patients remained high throughout. ...

ena Gutiérrez-Escolano It is known that levels of the anti-apoptotic protein survivin are reduced during Murine norovirus MNV-1 and Feline calicivirus (FCV) infection as part of the apoptosis establishment required for virus release and propagation in the host. Recently, our group has reported that overexpression of survivin causes a reduction of FCV protein synthesis and viral progeny production, suggesting that survivin may affect early steps of the replicative cycle. Using immunofluorescence assays, we observed that overexpression of survivin, resulted in the reduction of FCV infection not only in transfected...
