The recently developed human norovirus (HuNoV) B cell culture and mouse models hold promise for drug discovery and development but their suitability for antiviral studies has not been assessed. We demonstrate the inhibitory effect of the nucleoside analogue 2'-C-methylcytidine (2CMC) on HuNoV replication in the human B cell BJAB cell line and in Balb/c Rag/gamma chain-deficient (Rag-γc(-/-)) mice. These data suggest the applicability of both models for future study and development of antiviral drugs for the treatment of HuNoV infections.

Capsid Integrity qPCR (CI-qPCR) assays offer a promising alternative to cell culture-based infectivity assays for assessing pathogenic human virus viability in wastewater. This study compared three CI-qPCR methods: two novel (Crosslinker, TruTiter) and one established (PMAxx dye). These methods were evaluated on heat-inactivated and non-heat-inactivated 'live' viruses spiked into phosphate-buffered saline (PBS) and wastewater, as well as on viruses naturally present in wastewater samples.

Background: Human norovirus (HuNoV) is a major cause of enteric infectious gastroenteritis and is classified into several genotypes based on its capsid protein amino acid sequence and nucleotide sequence of the polymerase gene. Among these, GII.4 is the major genotype worldwide.

Background: Many viruses can cause persistent infection and/or viral shedding in immunocompromised hosts. This is a well-described occurrence not only with SARS-CoV-2 but for many other viruses as well. Understanding how viruses evolve and mutate in these patients and the global impact of this phenomenon is critical as the immunocompromised population expands.

Norovirus (NoV) infection is a leading cause of gastroenteritis and poses global health threats, with increasing incidence reported in immunocompromised individuals, which is further exacerbated by the globalization of the food industry. Eumelanin has demonstrated its potential in antiviral treatments, but its role in preventing viral infections remains underexplored. Therefore, in this study, we investigated the antiviral properties and potential mechanisms of self-assembled eumelanin nanoparticles (EmNPs) against Tulane virus (TuV), a surrogate with a similar infection mechanism to NoVs.
