Two defence systems eliminate plasmids from seventh pandemic Vibrio cholerae

Melanie Blokesch, David William Adams, Milena Jadwiga Jaskolska

Horizontal gene transfer can trigger rapid shifts in bacterial evolution. Driven by a variety of mobile genetic elements—in particular bacteriophages and plasmids—the ability to share genes within and across species underpins the exceptional adaptability o ...

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 ...

Microfluidic Platforms for the Study of Bacterial Metabolism and Antimicrobial Susceptibility Testing

Yang Liu

Fast spreading antimicrobial resistance (AMR) is an emerging major public health issue. New therapeutic and diagnostic paradigms must be implemented to counteract this evolution. In this respect, fast antimicrobial susceptibility testing (AST) plays an imp ...

Microtissue models for studying the dynamics of host-pathogen interactions in the urinary bladder

Kunal Sharma

Urinary tract infections (UTIs) are amongst the most common bacterial infections and are the second-most frequent reason for antibiotic prescriptions. Moreover, in about 25% of all treated cases, recurrence of infection occurs. Uropathogenic Escherichia co ...

Fabrication and characterization of cuminaldehyde-loaded electrospun gliadin fiber mats

Niloufar Sharif

This work's objective was to develop a novel type of gliadin electrospun fiber with antibacterial properties by incorporating cuminaldehyde in the fibrous structure. Gliadin fibers containing various concentrations of cuminaldehyde were fabricated via an e ...

Antimicrobial susceptibility testing by measuring bacterial oxygen consumption on an integrated platform

Martinus Gijs, Thomas Lehnert, Yang Liu

Cellular respiration is a fundamental feature of metabolic activity and oxygen consumption can be considered as a reliable indicator of bacterial aerobic respiration, including for facultative anaerobic bacteria like E. coli. Addressing the emerging global ...
