Vibrio 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 ...

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 ...

Machine learning and its impact on psychiatric nosology: Findings from a qualitative study among German and Swiss experts

The increasing integration of Machine Learning (ML) techniques into clinical care, driven in particular by Deep Learning (DL) using Artificial Neural Nets (ANNs), promises to reshape medical practice on various levels and across multiple medical fields. Mu ...

A Robotic Surgery Platform for Automated Tissue Micromanipulation in Zebrafish Embryos

Andrew Charles Oates, Mahmut Selman Sakar, Ece Özelçi, Laurel Ann Rohde, Erfan Etesami

Microsurgical manipulations are key experimental techniques in life science research, particularly in embryology. These techniques are most often performed manually by highly skilled scientists, posing limitations on speed, precision, and reproducibility. ...

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 ...

Solving the mystery of the missing plasmids in seventh pandemic Vibrio cholerae strains

Melanie Blokesch

The pathogen responsible for the continuing seventh cholera pandemic typically lacks self-replicating plasmids. Genetics, cell biology and bioinformatics analyses have identified two DNA-defence systems that protect bacterial populations from plasmids and ...

Human- and machine-centred designs of molecules and materials for sustainability and decarbonization

Sokseiha Muy, Tian Xie

Data-driven approaches based on high-throughput capabilities and machine learning hold promise in revolutionizing human-centred materials discovery for sustainability and decarbonization. This Review examines the strengths and limitations of different trad ...

Advances 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 ...

Neighbor predation linked to natural competence fosters the transfer of large genomic regions in Vibrio cholerae

Melanie Blokesch, Nicolas Jean Philippe Guex, Christian Iseli, Sandrine Stutzmann, Candice Stoudmann, Noémie Matthey

Natural competence for transformation is a primary mode of horizontal gene transfer. Competent bacteria are able to absorb free DNA from their surroundings and exchange this DNA against pieces of their own genome when sufficiently homologous. However, the ...

Genetics of human susceptibility to active and latent tuberculosis: present knowledge and future perspectives

Jacques Fellay, Nimisha Chaturvedi

Tuberculosis is an ancient human disease, estimated to have originated and evolved over thousands of years alongside modern human populations. Despite considerable advances in disease control, tuberculosis remains one of the world's deadliest communicable ...
