Update on Interfacial Charge Transfer (IFTC) Processes on Films Inactivating Viruses/Bacteria under Visible Light: Mechanistic Considerations and Critical Issues

Juan Kiwi, Sami Rtimi

This review presents an update describing binary and ternary semiconductors involving interfacial charge transfer (IFCT) in composites made up by TiO2, CuO, Ag2O and Fe2O3 used in microbial disinfection (bacteria and viruses). The disinfection mechanism, k ...

Pilus production in Acinetobacter baumannii is growth phase dependent and essential for natural transformation

Melanie Blokesch, Nina Vesel

Acinetobacter baumannii is a severe threat to human health as a frequently multidrug-resistant hospital-acquired pathogen. Part of the danger from this bacterium comes from its genome plasticity and ability to evolve quickly by taking up and recombining ex ...

Antiviral Screen against Canine Distemper Virus-Induced Membrane Fusion Activity

Gerardo Turcatti, Marc Chambon, Jonathan Patrice Vesin

Canine distemper virus (CDV), a close relative of the human pathogen measles virus (MeV), is an enveloped, negative sense RNA virus that belongs to the genus Morbillivirus and causes severe diseases in dogs and other carnivores. Although the vaccination is ...

Novel broad-spectrum virucidal antivirals

Matteo Gasbarri

The current COVID-19 pandemic has showed the threats that viruses can cause to the whole world. Over 200 million infections and over 4.5 million deaths and enormous socio-economic impact were the output of the emergence of a single new pathogen: SARS-CoV-2 ...

Resist or perish: Fate of a microbial population subjected to a periodic presence of antimicrobial

Anne-Florence Raphaëlle Bitbol, Loïc Marrec

The evolution of antimicrobial resistance can be strongly affected by variations of antimicrobial concentration. Here, we study the impact of periodic alternations of absence and presence of antimicrobial on resistance evolution in a microbial population, ...

Fast antimicrobial susceptibility testing onEscherichia coliby metabolic heat nanocalorimetry

Martinus Gijs, Thomas Lehnert, Yang Liu

Fast spreading of antimicrobial resistance is now considered a major global health threat. New technologies are required, enabling rapid diagnostics of bacterial infection combined with fast antimicrobial susceptibility testing (AST) for evaluating the eff ...

Adaptation of Pseudomonas aeruginosa to constant sub-inhibitory concentrations of quaternary ammonium compounds

Urs von Gunten, Giovanni Dietler, Sandor Kasas, Florian Frédéric Vincent Breider, Leonardo Venturelli, Myriam Borgatta, Margaux Océane Voumard

Quaternary ammonium compounds (QACs) are widely used in consumer products for disinfection purposes. QACs are frequently detected in aquatic systems at sub-inhibitory concentrations and were found to affect the development of antimicrobial resistance if ba ...

Biodegradation and Antimicrobial Properties of Zinc Oxide-Polymer Composite Materials for Urinary Stent Applications

Lorenzo Lucherini

Research advancements in the field of urinary stents have mainly been in the selection of materials and coatings to address commonly faced problems of encrustation and bacterial adhesion. In this study, polylactic acid (PLA) and polypropylene (PP) were eva ...

Modified cyclodextrins as broad-spectrum antivirals

Francesco Stellacci, Natalia Gasilova, Daniel Ortiz Trujillo, Valeria Cagno, Matteo Gasbarri, Samuel Thomas Jones, Matej Janecek

Viral infections kill millions of people and new antivirals are needed. Nontoxic drugs that irreversibly inhibit viruses (virucidal) are postulated to be ideal. Unfortunately, all virucidal molecules described to date are cytotoxic. We recently developed n ...
