Bactericidal 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 ...
2024Material 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 ...
AMER SOC MICROBIOLOGY2023Biofilm formation on human immune cells is a multicellular predation strategy of Vibrio cholerae
Alexandre Louis André Persat, Sofya Mikhaleva
Biofilm formation is generally recognized as a bacterial defense mechanism against environmental threats, including antibiotics, bacteriophages, and leukocytes of the human immune system. Here, we show that for the human pathogen Vibrio cholerae, biofilm f ...
CELL PRESS2023Biofilm morphogenesis on soft hydrogels
Bacteria often colonize their environment in the form of surface attached multicellular communities called biofilms. Biofilms grow from surface-attached cells that undergo division while self-embedding in a viscoelastic matrix. Biofilms grow at the surface ...
EPFL2023A Rapidly Responsive Sensor for Wireless Detection of Early and Mature Microbial Biofilms
Hubert Girault, Wanderson Oliveira Da Silva, Andreas Stephan Lesch, Bhawna Nagar
Biofilm-associated infections, which are able to resist antibiotics, pose a significant challenge in clinical treatments. Such infections have been linked to various medical conditions, including chronic wounds and implant-associated infections, making the ...
WILEY-V C H VERLAG GMBH2023The Effects of Spatial Organization and Fluid Flow on the Social Interactions in Microbial Communities
Bacteria often engage in social interactions with neighbouring bacteria. Ecosystems which are subjected to social interactions have been widely studied in well mixed settings such as test tubes, allowing us to identify the cellular components contributingt ...
EPFL2023Engineering extracellular electron transfer for enhanced energy harvesting in microbial electrochemical devices
Microorganisms known as exoelectrogens evolved the ability of transporting electrons across insulating biological membranes. In a physiological context, this enables respiration on extracellular electron acceptors and electron transfer to other organisms. ...
EPFL2023Recent advances in therapeutic targets identification and development of treatment strategies towards Pseudomonas aeruginosa infections
The opportunistic human pathogen Pseudomonas aeruginosa is the causal agent of a wide variety of infections. This non-fermentative Gram-negative bacillus can colonize zones where the skin barrier is weakened, such as wounds or burns. It also causes infecti ...
BMC2023Electrochemical imaging of metabolic activity in tissue and biofilms
Non-invasive and semi-invasive bioimaging is of great interest for the rapid diagnosis and efficient as well as specific treatments of biological systems affecting human health, such as cancer tissue and biofilms. Electrochemical bioimaging is one of the d ...
EPFL2022Advances in the Sensing and Treatment of Wound Biofilms
Hubert Girault, Sorour Darvishi
Wound biofilms represent a particularly challenging problem in modern medicine. They are increasingly antibiotic resistant and can prevent the healing of chronic wounds. However, current treatment and diagnostic options are hampered by the complexity of th ...
