Systematic mapping of antibiotic cross-resistance and collateral sensitivity with chemical genetics

Camille Véronique Bernadette Goemans, Florian Huber

By acquiring or evolving resistance to one antibiotic, bacteria can become resistant to a second one, due to shared underlying mechanisms. This is called cross-resistance (XR) and further limits therapeutic choices. The opposite scenario, in which initial ...

Homogeneous vs. heterogeneous photo-Fenton elimination of antibiotic-resistant bacteria bearing intracellular or extracellular resistance: Do resistance mechanisms interfere with disinfection pathways?

César Pulgarin, Stefanos Giannakis, Truong-Thien Melvin Le, Jérémie Decker

The present study aimed to fill the knowledge gap between the implications of intracellular and extracellular antibiotic resistance mechanisms may inflict on the inactivation pathways of the photo-Fenton process under mild conditions. It was thus designed ...

Capsular Polysaccharide Restrains Type VI Secretion in Acinetobacter baumannii

Melanie Blokesch, Loriane Bader, Mary-Claude Croisier-Coeytaux, Nicolas Olmo Flaugnatti

The type VI secretion system (T6SS) is a sophisticated, contact-dependent nanomachine involved in interbacterial competition. To function effectively, the T6SS must penetrate the membranes of both attacker and target bacteria. Structures associated with th ...

Accurate and rapid antibiotic susceptibility testing using a machine learning-assisted nanomotion technology platform

Sandor Kasas, Anthony Vocat, Gino Cathomen, Eric Delarze, Florian Tagini, Laura Munch

Antimicrobial resistance (AMR) is a major public health threat, reducing treatment options for infected patients. AMR is promoted by a lack of access to rapid antibiotic susceptibility tests (ASTs). Accelerated ASTs can identify effective antibiotics for t ...

Simple optical nanomotion method for single-bacterium viability and antibiotic response testing

Sandor Kasas, María Inés Villalba, Allan Bonvallat, Eugenia Rossetti

Antibiotic resistance is nowadays a major public health issue. Rapid antimicrobial susceptibility tests (AST) are one of the options to fight this deadly threat. Performing AST with single-cell sensitivity that is rapid, cheap, and widely accessible, is ch ...

Ozonation of organic compounds in water and wastewater: A critical review

Urs von Gunten, Sung Eun Lim

Ozonation has been applied in water treatment for more than a century, first for disinfection, later for oxidation of inorganic and organic pollutants. In recent years, ozone has been increasingly applied for enhanced municipal wastewater treatment for eco ...

Photodynamic treatment of multidrug-resistant bacterial infection using indium phosphide quantum dots

Francesco Stellacci, Inyoung Yonah Lee

Infections caused by multidrug-resistant (MDR) bacteria pose an impending threat to humanity, as the evolution of MDR bacteria outpaces the development of effective antibiotics. In this work, we use indium phosphide (InP) quantum dots (QDs) to treat infect ...

Probing the growth and mechanical properties of Bacillus subtilis biofilms through genetic mutation strategies

Chen Zhang, Lei Wang

Bacterial communities form biofilms on various surfaces by synthesizing a cohesive and protective extracellular matrix, and these biofilms protect microorganisms against harsh environmental conditions. Bacillus subtilis is a widely used experimental specie ...

Seasonal and spatial variability of antibiotic resistance genes and Class I integrons in the rivers of the Mekong delta, Vietnam

Pierre Rossi, Florian Frédéric Vincent Breider, Emmanuelle Rohrbach

Aquaculture activities are steadily expanding in Vietnam, covering an estimated 700,000 ha, with 89% of these culture ponds located in the Mekong Delta. Since 2009, large-scale bacterial epidemics have spread in response to this intensive cultivation. Anti ...
