Interactions 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 ...
2024Dangerous 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 ...
EPFL2024Resolving bacterial cell biology: from replisome dynamics to cell wall synthesis
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 ...
EPFL2024Host-derived organic acids enable gut colonization of the honey bee symbiont Snodgrassella alvi
Anders Meibom, Stéphane Laurent Escrig
Diverse bacteria can colonize the animal gut using dietary nutrients or by engaging in microbial crossfeeding interactions. Less is known about the role of host-derived nutrients in enabling gut bacterial colonization. Here we examined metabolic interactio ...
Berlin2024Bactericidal effect of tetracycline in E. coli strain ED1a may be associated with ribosome dysfunction
Camille Véronique Bernadette Goemans, Christian Eugen Zimmerli, Martin Beck
Ribosomes translate the genetic code into proteins. Recent technical advances have facilitated in situ structural analyses of ribosome functional states inside eukaryotic cells and the minimal bacterium Mycoplasma. However, such analyses of Gram-negative b ...
2024Stability 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 ...
2024Machine learning method for the classification of the state of living organisms' oscillations
Sandor Kasas, María Inés Villalba
The World Health Organization highlights the urgent need to address the global threat posed by antibiotic-resistant bacteria. Efficient and rapid detection of bacterial response to antibiotics and their virulence state is crucial for the effective treatmen ...
Frontiers Media Sa2024The microbial genomics of glacier-fed streams: adaptations to an extreme ecosystem
Glacier-fed streams are the cold, ultra-oligotrophic, and unstable streams that are fed by glacial meltwater. Despite these extreme conditions, they harbour a diverse and abundant microbial diversity that develops into biofilms, covering the boulders and s ...
EPFL2024Human alveolar lining fl uid from the elderly promotes Mycobacterium tuberculosis intracellular growth and translocation into the cytosol of alveolar epithelial cells
Vivek Vijay Thacker, Richa Mishra
The elderly population is highly susceptible to developing respiratory diseases, including tuberculosis, a devastating disease caused by the airborne pathogen Mycobacterium tuberculosis ( M.tb ) that kills one person every 18 seconds. Once M.tb reaches the ...
Elsevier Science Inc2024Homogeneous 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 ...
