Relationship Between Inactivation and Genome Damage of Human Enteroviruses Upon Treatment by UV254, Free Chlorine, and Ozone

Tamar Kohn, Virginie Bachmann, Jason Robert Torrey, Suzanne Marie Young

Quantitative PCR (qPCR) is a convenient tool for monitoring virus concentrations in water and wastewater treatment trains, though it only informs about virus presence, but not infectivity. This limitation can be overcome if the relationship between infecti ...

Inhibition of influenza virus activity by the bovine seminal plasma protein PDC-109

Christian Sieben

A number of viruses causing sexually transmissible diseases are transmitted via mammalian seminal plasma. Several components of seminal plasma have been shown to influence those viruses and their physiological impact. To unravel whether components of semin ...

Differential immunodominance hierarchy of CD8+ T cell responses in HLA-B27:05 and B27:02-mediated control of HIV-1 infection

Jacques Fellay

The well-characterised association between HLA-B27:05 and protection against HIV disease progression has been linked to immunodominant HLA-B27:05-restricted CD8+ T-cell responses towards the conserved Gag 263-272 ('KK10') and Pol 901-909 'KY9' epitopes. ...

Dissecting HIV Virulence: Heritability of Setpoint Viral Load, CD4+ T Cell Decline and Per-Parasite Pathogenicity

Jacques Fellay

Pathogen strains may differ in virulence because they attain different loads in their hosts, or because they induce different disease-causing mechanisms independent of their load. In evolutionary ecology, the latter is referred to as" per-parasite pathogen ...

Viral genetic variation accounts for a third of variability in HIV-1 set-point viral load in Europe

Jacques Fellay

HIV-1 set-point viral load-the approximately stable value of viraemia in the first years of chronic infection-is a strong predictor of clinical outcome and is highly variable across infected individuals. To better understand HIV-1 pathogenesis and the evol ...

On the Analysis of Intrahost and Interhost Viral Populations: Human Cytomegalovirus as a Case Study of Pitfalls and Expectations

Jeffrey David Jensen, Susanne Petra Pfeifer, Sebastian Matuszewski

Intrahost and interhost assessments of viral diversity are often treated as measures of separate and distinct evolutionary processes, with numerous investigations reporting seemingly incompatible results between the two. For example, in human cytomegalovir ...

The Combined Effect of Oseltamivir and Favipiravir on Influenza A Virus Evolution

Jeffrey David Jensen, Claudia Bank, Sebastian Matuszewski, Nicky Louise Ormond

Influenza virus inflicts a heavy death toll annually and resistance to existing antiviral drugs has generated interest in the development of agents with novel mechanisms of action. Favipiravir is an antiviral drug that acts by increasing the genome-wide mu ...

Experimental adaptation of human echovirus 11 to ultraviolet radiation leads to tolerance to disinfection and resistance to ribavirin

Tamar Kohn, Jeffrey David Jensen, Anna Carratala Ripolles, Virginie Bachmann, Qingxia Zhong, Hyunjin Shim

Ultraviolet light in the UVC range is a commonly used disinfectant to control viruses in clinical settings and water treatment. Here, we employed an experimental evolution approach to investigate the adaptation of human echovirus 11 to disinfection by UVC, ...
