The paper investigates how freshwater microbial communities influence viral inactivation, finding that specific bacterial taxa, rather than community diversity, drive differences in virus removal rates.

The paper investigates the inactivation kinetics and mechanisms of three enteric viruses in lakewater, showing differences in their decay rates and the role of microbial proteases and capsid integrity.

The paper develops ICC-NanoporeSeq to detect and quantify infectious Enterovirus B types in environmental samples, enabling type-resolved infectivity assessment.

The paper identifies a single capsid residue in Echovirus 11 that determines its susceptibility to proteolytic inactivation in freshwater.

This study demonstrates the ability to detect and discriminate microcystin congeners at sub-nanomolar concentrations using aerolysin nanopores, with applications for environmental monitoring.

This study examines how zooplankton affect virus inactivation under sunlight and darkness, finding species-specific impacts on virus removal rates.

This study shows that the rate of osmotic pressure change during droplet evaporation predicts bacterial inactivation in drying respiratory droplets.

The paper characterizes proteolytic activity in Lake Geneva, identifying cleavage preferences and protease types contributing to peptidic contaminant degradation.

The paper compares nasal and bronchial mucus from human airway cultures to identify components that influence influenza A virus inhibition.

This study shows lognormal distributions accurately model enteric virus concentrations in wastewater, outperforming other distributions, and suggests weekly monitoring for effective and cost-effective tracking.

This study investigates how relative humidity and aerosol composition affect influenza A virus infectivity in aerosol particles, finding that low humidity and efflorescence preserve infectivity longer than intermediate humidity conditions.

This study quantifies how salt concentration affects influenza A virus inactivation in drying droplets and explains airborne virus transmission mechanisms.

This study examines how organic compounds affect the stability of influenza A virus in droplets, finding that proteins enhance virus stability by altering drying dynamics and efflorescence RH.

This study shows that respiratory commensal bacteria enhance the stability of influenza A virus in droplets and aerosols, suggesting the microbiota may influence viral transmission risks.

This study investigates how amino acid substitutions in coxsackievirus B5 capsid proteins affect sensitivity to free chlorine and heat, finding that capsid changes have a minor role in chlorine sensitivity but reduce heat sensitivity in specific mutants.
