Mechanism ofcyclic beta-glucan export by ABC transporter Cgt of Brucella

Henning Paul-Julius Stahlberg, Dongchun Ni

Polysaccharides play critical roles in bacteria, including the formation of protective capsules and biofilms and establishing specific host cell interactions. Their transport across membranes is often mediated by ATP-binding cassette (ABC) transporters, wh ...

Pilus production in Acinetobacter baumannii is growth phase dependent and essential for natural transformation

Melanie Blokesch, Nina Vesel

Acinetobacter baumannii is a severe threat to human health as a frequently multidrug-resistant hospital-acquired pathogen. Part of the danger from this bacterium comes from its genome plasticity and ability to evolve quickly by taking up and recombining ex ...

Phototransformation kinetics of cyanobacterial toxins and secondary metabolites in surface waters

Sandro Marcotullio

Background Cyanobacteria and their toxins occur in high concentrations during the so-called bloom events in surface waters. To be able to assess the risks associated with cyanobacterial blooms, we need to understand the persistence and fate processes of th ...

The influence of the crowding assumptions in biofilm simulations

Vassily Hatzimanikatis, Liliana Angeles Martinez

Author summary In nature, many organisms grow in crowded biofilms that protect against stressful conditions, making their control/eradication a challenge. Modeling these microbial systems is a valuable tool for studying the interactions among cells and exp ...

Soft-probe-scanning electrochemical microscopy reveals electrochemical surface reactivity of E. coli biofilms

Hubert Girault, Emad Oveisi, Andreas Stephan Lesch, Horst Pick, Sorour Darvishi

Investigating and understanding dynamic biofilm growth mechanisms is challenging, often because state-of-the-art optical characterization tools provide limited information. Micrometric electrochemical imaging of Escherichia coli biofilms using Soft-Probe-S ...

Adaptation of Pseudomonas aeruginosa to constant sub-inhibitory concentrations of quaternary ammonium compounds

Giovanni Dietler, Urs von Gunten, Sandor Kasas, Florian Frédéric Vincent Breider, Leonardo Venturelli, Margaux Océane Voumard

Quaternary ammonium compounds (QACs) are widely used in consumer products for disinfection purposes. QACs are frequently detected in aquatic systems at sub-inhibitory concentrations and were found to affect the development of antimicrobial resistance if ba ...

Iron sequestration by transferrin 1 mediates nutritional immunity in Drosophila melanogaster

Bruno Lemaitre, Jean Philippe Boquete, Alice Marra, Igor Iatsenko

Iron sequestration is a recognized innate immune mechanism against invading pathogens mediated by iron-binding proteins called transferrins. Despite many studies on antimicrobial activity of transferrins in vitro, their specific in vivo functions are poorl ...

Biofilms deform soft surfaces and disrupt epithelia

Alexandre Louis André Persat, Tamara Rossy, Alice Cont, Zaïnebe Dhirani

During chronic infections and in microbiota, bacteria predominantly colonize their hosts as multicellular structures called biofilms. A common assumption is that biofilms exclusively interact with their hosts biochemically. However, the contributions of me ...

Genomic Characterization of Mycobacterium lepraeto Explore Transmission Patterns Identifies New Subtype in Bangladesh

Stewart Cole, Andrej Benjak, Charlotte Avanzi

Mycobacterium leprae, the causative agent of leprosy, is an unculturable bacterium with a considerably reduced genome (3.27 Mb) compared to homologues mycobacteria from the same ancestry. In 2001, the genome ofM. lepraewas first described and subsequently ...
