Stability of influenza A virus in droplets and aerosols is heightened by the presence of commensal respiratory bacteria

Tamar Kohn, Athanasios Nenes, Ghislain Gilles Jean-Michel Motos, Htet Kyi Wynn, Kalliopi Violaki, Céline Terrettaz, Aline Laetitia Schaub, Walter Hugentobler, Shannon Christa David, Laura José Costa Henriques, Daniel Scott Nolan, Marta Augugliaro

Aerosol transmission remains a major challenge for control of respiratory viruses, particularly those causing recurrent epidemics, like influenza A virus (IAV). These viruses are rarely expelled alone, but instead are embedded in a consortium of microorgan ...

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 ...

Resolving bacterial cell biology: from replisome dynamics to cell wall synthesis

Chen Zhang

Bacteria are ubiquitous single cellular organisms. Compared to eukaryotic cells, bacteria have two unique characteristics: the membrane-less nucleoid and the cell wall built of peptidoglycan (PG). In most bacteria, a single circular chromosome is compacted ...

CSF-contacting neurons respond to Streptococcus pneumoniae and promote host survival during central nervous system infection

Ludovic Pierre Gustave Keiser, Laura Desban

The pathogenic bacterium Streptococcus pneumoniae (S. pneumoniae) can invade the cerebrospinal fluid (CSF) and cause meningitis with devastating consequences. Whether and how sensory cells in the central nervous system (CNS) become activated during bacteri ...

Characterization of Pseudomonas aeruginosa mechanosensing through label-free imaging of type IV pili

Lorenzo Anton-Louis Talà

Bacteria are ubiquitously found in all sorts of environment. They're found in the ocean, soil, or even in our guts or on our skin. Independently of their niche, they can transition from a planktonic state were they freely swim in an aqueous environment to ...

Irreversible inactivation of carbapenem-resistant Klebsiella pneumoniae and its genes in water by photo-electro-oxidation and photo-electro-Fenton- Processes action modes

César Pulgarin

Carbapenem-resistant Klebsiella pneumoniae is a critical priority pathogen according to the World Health Organization's classification. Effluents of municipal wastewater treatment plants (EWWTP) may be a route for K. pneumoniae dissemination. Herein, the i ...

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 ...

Identification of a Dps contamination in Mitomycin-C–induced expression of Colicin Ia

Henning Paul-Julius Stahlberg

Colicins are bacterial toxins targeting Gram-negative bacteria, including E. coli and related Enterobacteriaceae strains. Some colicins form ion-gated pores in the inner membrane of attacked bacteria that are lethal to their target. Colicin Ia was the firs ...

A high-content image-based drug screen of clinical compounds against cell transmission of adenovirus

Gerardo Turcatti, Fabien Kuttler

Human adenoviruses (HAdVs) are fatal to immuno-suppressed individuals, but no effective anti-HAdV therapy is available. Here, we present a novel image-based high-throughput screening (HTS) platform, which scores the full viral replication cycle from virus ...

cis-regulatory variation modulates susceptibility to enteric infection in the Drosophila genetic reference panel

Bart Deplancke, Vincent Roland Julien Gardeux, Maroun Bou Sleiman, Virginie Sandra Braman, Riccardo Dainese, Maria Litovchenko, Michael Vincent Frochaux, Dani Osman, Brian Dennis Hollis, Tommaso Andreani

Background: Resistance to enteric pathogens is a complex trait at the crossroads of multiple biological processes. We have previously shown in the Drosophila Genetic Reference Panel (DGRP) that resistance to infection is highly heritable, but our understan ...

Occurrence and ecological determinants of the contamination of floodplain wetlands with Klebsiella pneumoniae and pathogenic or antibiotic-resistant Escherichia coli

François Gillet, Charles Pierre Roger Henriot

The survival and multiplication of human pathogenic and antibiotic-resistant bacteria in ecosystems is of increasing concern but has been little explored. Wetlands can be contaminated by water fluxes from rivers and may present environmental conditions lea ...

Population Structure, Molecular Epidemiology, and beta-Lactamase Diversity among Stenotrophomonas maltophilia Isolates in the United States

Luciano Andres Abriata

Stenotrophomonas maltophilia is a Gram-negative, nonfermenting, environmental bacillus that is an important cause of nosocomial infections, primarily associated with the respiratory tract in the immunocompromised population. Aiming to understand the popula ...

Analysis of antibiotic multi-resistant bacteria and resistance genes in the effluent of an intensive shrimp farm (Long An, Vietnam)

Pierre Rossi, Luiz Felippe De Alencastro

In Vietnam, intensive shrimp farms heavily rely on a wide variety of antibiotics (ABs) to treat animals or prevent disease outbreak. Potential for the emergence of multi-resistant bacteria is high, with the concomitant contamination of adjacent natural aqu ...

Bacterial traps and advances in nanobiotechnology for atomic force microscopy

Oliver Peric

The atomic force microscope (AFM) allows the analysis of living microorganisms in physiological conditions on the nanometer scale. The observation of bacteria in physiological aqueous medium necessitates a robust immobilization of the bacterium to the surf ...

Solar photo-Fenton disinfection of 11 antibiotic-resistant bacteria (ARB) and elimination of representative AR genes. Evidence that antibiotic resistance does not imply resistance to oxidative treatment

César Pulgarin, Stefanos Giannakis, Truong-Thien Melvin Le

The emergence of antibiotic resistance represents a major threat to human health. In this work we investigated the elimination of antibiotic resistant bacteria (ARB) by solar light and solar photo-Fenton processes. As such, we have designed an experimental ...
