Stability of influenza A virus in droplets and aerosols is heightened by the presence of commensal respiratory bacteria
Athanasios Nenes, Tamar Kohn, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos, Aline Laetitia Schaub, Shannon Christa David, Walter Hugentobler, Htet Kyi Wynn, Céline Terrettaz, 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 ...
2024Using Negative Control Populations to Assess Unmeasured Confounding and Direct Effects
Sometimes treatment effects are absent in a subgroup of the population. For example, penicillin has no effect on severe symptoms in individuals infected by resistant Staphylococcus aureus, and codeine has no effect on pain in individuals with certain polym ...
Lippincott Williams & Wilkins2024Microfluidic systems for infectious disease diagnostics
Microorganisms, encompassing both uni- and multicellular entities, exhibit remarkable diversity as omnipresent life forms in nature. They play a pivotal role by supplying essential components for sustaining biological processes across diverse ecosystems, i ...
Cambridge2024Dangerous acquaintances: the interplay between type IV pili and the type VI secretion system during Vibrio cholerae's environmental lifestyle
Cholera, caused by the bacterium Vibrio cholerae, has affected humanity throughout history and still impacts millions of people every year. Apart from being a human pathogen, V. cholerae is a common member of the aquatic environment. Due to this natural re ...
EPFL2024Vibrio cholerae pathogenicity island 2 encodes two distinct types of restriction systems
Melanie Blokesch, David William Adams, Alexandre Lemopoulos, Grazia Vizzarro
In response to predation by bacteriophages and invasion by other mobile genetic elements such as plasmids, bacteria have evolved specialised defence systems that are often clustered together on genomic islands. The O1 El Tor strains of Vibrio cholerae resp ...
2024Interactions between pili affect the outcome of bacterial competition driven by the type VI secretion system
Melanie Blokesch, Anne-Florence Raphaëlle Bitbol, Alexandre Lemopoulos, Richard Marie Servajean, Simon Bernhard Otto
The bacterial type VI secretion system (T6SS) is a widespread, kin-discriminatory weapon capable of shaping microbial communities. Due to the system’s dependency on contact, cellular interactions can lead to either competition or kin protection. Cell-to-ce ...
2024Homogeneous 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 ...
London2024Electrospun zein incorporating phycocyanin and Spirulina extract: Fabrication, characterization, and potential application
Electrospinning was used to develop zein fibers containing phycocyanin and aqueous-ethanolic extract of Spirulina (AEES) for elucidating the potent packaging properties of phycocyanin and AEES on walnut samples. Morphological results revealed that using th ...
Amsterdam2023The tip protein PAAR is required for the function of the type VI secretion system
Bacteria are constantly competing to colonize crowded ecological niches, such as the human gut. The type VI secretion system (T6SS) is a critical bacterial weapon in this warfare. It resembles a crossbow with a poisoned arrow allowing bacteria to inject to ...
Washington2023Material Substrate Physical Properties Control Pseudomonas aeruginosa Biofilm Architecture
Alexandre Louis André Persat, Alice Cont
The biofilm lifestyle is the most widespread survival strategy in the bacterial world. Pseudomonas aeruginosa biofilms cause chronic infections and are highly recalcitrant to antimicrobials. The genetic requirements allowing P. aeruginosa to grow into biof ...
