Biofilm 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 ...

System for automated and dynamic cell culture

Julia Tischler

The present relates to a system for automated cell culture, the system comprising an inflow module, a cell culture plate and an outflow module, said inflow module being in fluid connection with the outflow module via the cell culture plate, the inflow modu ...

Sporadic type VI secretion in seventh pandemic Vibrio cholerae

Melanie Blokesch, Sandrine Stutzmann, Nicolas René Chiaruttini, Alexis Joseph Proutière, Loriane Bader, Lisa Christina Metzger, Natalia Carolina Drebes Dorr, Sandrine Natacha Isaac

Vibrio cholerae is a pathogen that causes disease in millions of people every year by colonizing the small intestine and then secreting the potent cholera toxin. How the pathogen overcomes the colonization barrier created by the host’s natural microbiota i ...

PDMS filter structures for size-dependent larval sorting and on-chip egg extraction of C. elegans

Martinus Gijs, Hüseyin Baris Atakan, Furkan Ayhan

C. elegans-based assays require age-synchronized populations prior to experimentation to achieve standardized sets of worm populations, due to which age-induced heterogeneous phenotyping effects can be avoided. There have been several approaches to synchro ...

Comparison of chitin‐induced natural transformation in pandemic Vibrio cholerae O1 El Tor strains

Melanie Blokesch, Sandrine Stutzmann

The human pathogen Vibrio cholerae serves as a model organism for many important processes ranging from pathogenesis to natural transformation, which has been extensively studied in this bacterium. Previous work has deciphered important regulatory circuits ...

Automated Platform for Long-Term Culture and High-Content Phenotyping of Single C. elegans Worms

Johan Auwerx, Martinus Gijs, Matteo Cornaglia, Laurent Mouchiroud, Rongrong Xiang, Elena Katsyuba, Hüseyin Baris Atakan

The nematode Caenorhabditis elegans is a suitable model organism in drug screening. Traditionally worms are grown on agar plates, posing many challenges for long-term culture and phenotyping of animals under identical conditions. Microfluidics allows for ' ...

Highly Reduced Genome of the New Species Mycobacterium uberis, the Causative Agent of Nodular Thelitis and Tuberculoid Scrotitis in Livestock and a Close Relative of the Leprosy Bacilli

Stewart Cole, Andrej Benjak, Charlotte Avanzi

Nodular thelitis is a chronic enzootic infection affecting dairy cows and goats. The causative agent was recently shown to be related to the leprosy-causing bacilli Mycobacterium leprae and Mycobacterium lepromatosis. In this study, the genome of this path ...

Detection of antimicrobial resistance-associated proteins by titanium dioxide-facilitated intact bacteria mass spectrometry

Hubert Girault, Horst Pick, Natalia Gasilova, Liang Qiao, Milica Jovic, Yingdi Zhu

Titanium dioxide-modified target plates were developed to enhance intact bacteria analysis by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The plates were designed to photocatalytically destroy the bacterial envelope struct ...

Insight into the catalyst/photocatalyst microstructure presenting the same composition but leading to a variance in bacterial reduction under indoor visible light

César Pulgarin, Juan Kiwi, Sami Rtimi

Insight into two different uniform atomic-scale microstructures of Cu-and Ti-oxides sputtered on polyethylene (PET) presenting different redox properties and a distinct bacterial inactivation dynamics. Co-sputtered (CuOx-TiO2-PET) consists mainly of CuO. I ...
