Uptake without inactivation of human adenovirus type 2 by Tetrahymena pyriformis ciliates

Human adenoviruses are ubiquitous contaminants of surface water. Indigenous protists may interact with adenoviruses and contribute to their removal from the water column, though the associated kinetics and mechanisms differ between protist species. In this ...

Toward biocontrol of waterborne pathogens: contributions of protists to virus removal and associated mechanisms

Margot Ninon Lauren Olive

Human viruses are widespread in the water environment and pose a risk to human health. Wastewater effluents represent the main source of viruses discharge in the environment, leading to contamination of aquatic ecosystems. Viral pathogens can persist on th ...

Control of Waterborne Human Viruses by Indigenous Bacteria and Protists Is Influenced by Temperature, Virus Type, and Microbial Species

Tamar Kohn, Margot Ninon Lauren Olive, Anna Carratala Ripolles

Human viruses are ubiquitous contaminants in surface waters, where they can persist over extended periods of time. Among the factors governing their environmental persistence, the control (removal or inactivation) by microorganisms remains poorly understoo ...

Viral Transfer and Inactivation through Zooplankton Trophic Interactions

Tamar Kohn, Virginie Bachmann, Xavier Fernandez Cassi, Margot Ninon Lauren Olive

Waterborne viruses are responsible for numerous diseases and are abundant in aquatic systems. Understanding the fate of viruses in natural systems has important implications for human health. This research quantifies the uptake of bacteriophage T4 and the ...

Monitoring particulate fouling of North Sea water with SDI and new ASTM MFI0.45 test

Margot Ninon Lauren Olive

For assessing the particulate fouling of water, the modified fouling index (MFI0.45) is a superior test to the silt density index (SDI). There is a need to compare both tests in terms of sensitivity, how they are affected by the filter material and the typ ...
