Variability in Disinfection Resistance between Currently Circulating Enterovirus B Serotypes and Strains

Tamar Kohn, Simon Meister, Matthew Eric Verbyla

The susceptibility of waterborne viruses to disinfection is known to vary between viruses and even between closely related strains, yet the extent of this variation is not known. Here, different enteroviruses (six strains of coxsackievirus B5, two strains ...

Ozone and chlorine reactions with dissolved organic matter - Assessment of oxidant-reactive moieties by optical measurements and the electron donating capacities

Urs von Gunten

Oxidation processes are impacted by the type, concentration and reactivity of the dissolved organic matter (DOM). In this study, the reactions between various types of DOM (Suwannee River fulvic acid (SRFA), Nordic Reservoir NOM (NNOM) and Pony Lake fulvic ...

Genotypic, phenotypic and mechanistic insights into viruses with resistance to common water disinfectants

Qingxia Zhong

Infectious diseases caused by waterborne viruses contribute to the global disease burden. An effective barrier to prevent the discharge of waterborne viruses is a disinfection step, yet disinfection is not always efficient at inactivating viruses. This the ...

Cross-resistance of UV- or chlorine dioxide-resistant echovirus 11 to other disinfectants

Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann, Qingxia Zhong

The emergence of waterborne viruses with resistance to disinfection has been demonstrated in the laboratory and in the environment. Yet, the implications of such resistance for virus control remain obscure. In this study we investigate if viruses with resi ...

Resistance of echovirus 11 to ClO2 is associated with enhanced host receptor use, altered entry routes and high fitness

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

Waterborne viruses can exhibit resistance to common water disinfectants, yet the mechanisms that allow them to tolerate disinfection are poorly understood. Here, we generated echovirus 11 (E11) with resistance to chlorine dioxide (ClO2) by experimental evo ...

Genetic, structural and phenotypic properties of MS2 coliphage with resistance to ClO2 disinfection

Tamar Kohn, Anna Carratala Ripolles, Petr Leiman, Virginie Bachmann, Sergey Nazarov, Qingxia Zhong, Ricardo Cesar Guerrero Ferreira

Common water disinfectants like chlorine have been reported to select for resistant viruses, yet little attention has been devoted to characterizing disinfection resistance. Here, we investigated the resistance of MS2 coliphage to inactivation by chlorine ...

Solid oxide fuel cell anode degradation by the effect of hydrogen chloride in stack and single cell environments

Christian Ludwig, Jan Van Herle, Stefan Diethelm, Hossein Madi

The poisoning effect by hydrogen chloride (HCl) on state-of-the-art Ni anode-supported solid oxide fuel cells (SOFCs) at 750 degrees C is evaluated in either hydrogen or syngas fuel. Experiments are performed on single cells and short stacks and HCl concen ...
