Comparison of Three Viral Nucleic Acid Preamplification Pipelines for Sewage Viral Metagenomics

Viral metagenomics is a useful tool for detecting multiple human viruses in urban sewage. However, more refined protocols are required for its effective use in disease surveillance. In this study, we investigated the performance of three different preampli ...

Joint host-pathogen genomic analysis identifies hepatitis B virus mutations associated with human NTCP and HLA class I variation

Jacques Fellay, Bruno Emanuel Ferreira De Sousa Correia, Zhi Ming Xu, Andreas Scheck, Dylan Lawless, Olivier Noël Marie Naret, Arne Schneuing, David Gfeller, Thomas Junier, Sina Rüeger

Evolutionary changes in the hepatitis B virus (HBV) genome could reflect its adaptation to host -induced selective pressure. Leveraging paired human exome and ultra -deep HBV genome-sequencing data from 567 affected individuals with chronic hepatitis B, we ...

Ligand concentration determines antiviral efficacy of silica multivalent nanoparticles

Francesco Stellacci, Paulo Henrique Jacob Silva, Quy Ong Khac, Xufeng Xu, Rémi Andréa La Polla, Heyun Wang

We have learned from the recent COVID-19 pandemic that the emergence of a new virus can quickly become a global health burden and kill millions of lives. Antiviral drugs are essential in our fight against viral diseases, but most of them are virus-specific ...

Viral Genetic Determinants of Prolonged Respiratory Syncytial Virus Infection Among Infants in a Healthy Term Birth Cohort

Jacques Fellay, Zhi Ming Xu, Dylan Lawless, Thomas Junier

Background. Respiratory syncytial virus (RSV) is associated with acute respiratory infection. We sought to identify RSV variants associated with prolonged infection. Methods. Among healthy term infants we identified those with prolonged RSV infection and c ...

Susceptibility of enveloped and non-enveloped viruses to ultraviolet light-emitting diode (UV-LED) irradiation and implications for virus inactivation mechanisms

Shotaro Torii

Ultraviolet (UV) light-emitting diodes (UV-LEDs), a disinfection technology, efficiently inactivate pathogens in water. However, the assessment of UV-LED treatment and the mechanisms of UV inactivation on viruses (especially enveloped viruses) are limited. ...

Phylogenetic estimation of the viral fitness landscape of HIV-1 set-point viral load

Jacques Fellay, Luca Ferretti

Set-point viral load (SPVL), a common measure of human immunodeficiency virus (HIV)-1 virulence, is partially determined by viral genotype. Epidemiological evidence suggests that this viral property has been under stabilising selection, with a typical opti ...

Viral diversity is linked to bacterial community composition in alpine stream biofilms

Tom Ian Battin, Hannes Markus Peter, Paraskevi Pramateftaki, Meriem Bekliz

Biofilms play pivotal roles in fluvial ecosystems, yet virtually nothing is known about viruses in these communities. Leveraging an optimized sample-to-sequence pipeline, we studied the spatiotemporal turnover of dsDNA viruses associated with stream biofil ...

Risk assessment of waterborne viruses for recreational sites in Lake Geneva

Tamar Kohn, Xavier Fernandez Cassi, Chaojie Li, Timothy R. Julian

Norovirus is the most acute species among the viruses studied according to the simulations while enterovirus poses the least danger. The relative distance to the contamination sources, wind conditions as well as inactivation rates are essential in determin ...

Effect of wastewater treatment and environmental exposure on an enterovirus population

Odile Marie Clotilde Hervás de Nalda-Larivé

The presence of viruses in recreational water can present a risk for human health and wastewater effluent is a source of virus in the environment. Their persistence in the environment influences their probability to find a new host. Studies have shown that ...

Genotype-Dependent Kinetics of Enterovirus Inactivation by Free Chlorine and Ultraviolet (UV) Irradiation

Tamar Kohn, Shotaro Torii

Inactivation kinetics of enterovirus by disinfection is often studied using a single laboratory strain of a given genotype. Environmental variants of enterovirus are genetically distinct from the corresponding laboratory strain, yet it is poorly understood ...
