Type IV pili mechanochemically regulate virulence factors in Pseudomonas aeruginosa

Alexandre Louis André Persat, Joanne Netter Engel

Bacteria have evolved a wide range of sensing systems to appropriately respond to environmental signals. Here we demonstrate that the opportunistic pathogen Pseudomonas aeruginosa detects contact with surfaces on short timescales using the mechanical activ ...

Structure and properties of the C-terminal beta-helical domain of VgrG protein from Escherichia coli O157

Petr Leiman

The bacterial Type 6 secretion system (T6SS) translocates protein toxins (also called effectors) from the cytosol of a T6SS-carrying cell to a target cell by a syringe-like supramolecular complex resembling a contractile tail of bacteriophages. Valine-glyc ...

Ultra-soft cantilevers and 3-D micro-patterned substrates for contractile bundle tension measurement in living cells

Jean-Jacques Meister, Niccolo Piacentini, Chiara Gabella, Benoît Vianay

Actin-myosin microfilament bundles or stress-fibers are the principal tension-generating structures in the cell. Their mechanical properties are critical for cell shape, motion, and interaction with other cells and extracellular matrix, but were so far dif ...

Combined scanning transmission X-ray and electron microscopy for the characterization of bacterial endospores

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Paul Pao-Yun Shao, Imrich Barak, Jan Jamroskovic

Endospores (also referred to as bacterial spores) are bacterial structures formed by several bacterial species of the phylum Firmicutes. Spores form as a response to environmental stress. These structures exhibit remarkable resistance to harsh environmenta ...

In situ structural analysis of the Yersinia enterocolitica injectisome

Henning Paul-Julius Stahlberg, Matteo Dal Peraro, Marco Stenta, Matteo Thomas Degiacomi

Injectisomes are multi-protein transmembrane machines allowing pathogenic bacteria to inject effector proteins into eukaryotic host cells, a process called type III secretion. Here we present the first three-dimensional structure of Yersinia enterocolitica ...

Movement of Artificial Bacterial Flagella in Heterogeneous Viscous Environments at the Microscale

Lei Zhang

Swimming microrobots have the potential to be used in medical applications such as targeted drug delivery. The challenges for navigating microrobots in the human body lie not only in the viscosity of body fluids but also in the existence of different types ...

Taxonomic characterisation of Pseudomonas strain L48 and formal proposal of Pseudomonas entomophila sp nov.

Bruno Lemaitre

An entomopathogenic, Gram-negative bacterium isolated from a female specimen of the fruit fly Drosophila melanogaster was taxonomically characterised. Strain L48(T) was strictly aerobic, non-fermentative, oxidase and catalase positive, rod-shaped, and moti ...

Locomotion through Reconfiguration based on Motor Primitives for Roombots Self-Reconfigurable Modular Robots

Auke Ijspeert, Massimo Vespignani, Alexander Spröwitz, Rico Möckel, Stéphane Bonardi

We present the hardware and reconfiguration experiments for an autonomous self-reconfigurable modular robot called Roombots (RB). RB were designed to form the basis for self-reconfigurable furniture. Each RB module contains three degrees of freedom that ha ...

Biogrout propagation in soils

Lyesse Laloui

Microbial Induced Calcite Precipitation (MICP) is an innovative technique for soil grouting in which injected bacteria supplemented with chemicals lead to calcite precipitation in soils. A comprehensive research work is carried out to better understand and ...

Highly Diverse and Seasonally Dynamic Protist Community in a Pristine Peat Bog

Edward Mitchell, Enrique Lara

Culture-independent molecular methods based on the amplification, cloning and sequencing of small-subunit ribosomal RNA genes (SSU rDNAs) are powerful tools to study the diversity of microorganisms. Despite so, the eukaryotic microbial diversity of many ec ...
