Antagonistic response regulators spatially regulate receptor methylation in the Pseudomonas aeruginosa Pil-Chp surface sensing system

Alexandre Louis André Persat, Marco Julian Kühn

Most bacterial chemosensory systems encode enzymes that are predicted to methylate and demethylate their chemoreceptors to control signaling activity. Here, we show that a predicted methyltransferase (PilK) and methylesterase (ChpB) methylate and demethyla ...

Automatic identification of atmospheric bioaerosol using real-time imaging and fluorescence

Sophie Catherine Erb

Since the 1960s, the prevalence of pollen allergy has increased worldwide in developed countries and this trend is continuing, exacerbated by climate change. In the 20th century, operational pollen monitoring networks have been set-up to respond to the nee ...

Mapping Brain Morphology with Micro-CT and Topological Data Analysis: From Drosophila to General Applications

Samuel Sagar Kumar

Few organisms offer a window as precise and tractable into the exploration of biological form as Drosophila melanogaster. Yet the extraordinary natural variation in its brain morphology has remained largely uncharted, restrained by limitations in imaging, ...

Discovery and Biosynthesis of Persiathiacins: Unusual Polyglycosylated Thiopeptides Active Against Multidrug Resistant Tuberculosis

Stewart Cole, Anthony Vocat

Thiopeptides are ribosomally biosynthesized and post-translationally modified peptides (RiPPs) that potently inhibit the growth of Gram-positive bacteria by targeting multiple steps in protein biosynthesis. The poor pharmacological properties of thiopeptid ...

3D Silver Dendrites for Single-molecule Imaging by Surface-enhanced Raman Spectroscopy

Siarhei Zavatski

Discovery of surface-enhanced Raman scattering (SERS) followed by evolution of optical systems and nanoengineering approaches has paved a path to detection of essential organic molecules on solid SERS-active substrates from solutions at concentrations attr ...

Occurrence and ecological determinants of the contamination of floodplain wetlands with Klebsiella pneumoniae and pathogenic or antibiotic-resistant Escherichia coli

François Gillet, Charles Pierre Roger Henriot

The survival and multiplication of human pathogenic and antibiotic-resistant bacteria in ecosystems is of increasing concern but has been little explored. Wetlands can be contaminated by water fluxes from rivers and may present environmental conditions lea ...

An intracellular replication niche for Vibrio cholerae in the amoeba Acanthamoeba castellanii

Melanie Blokesch, Catherine Maclachlan, Charles Ulric V Van der Henst

Vibrio cholerae is a human pathogen and the causative agent of cholera. The persistence of this bacterium in aquatic environments is a key epidemiological concern, as cholera is transmitted through contaminated water. Predatory protists, such as amoebae, a ...

Cell Morphology and Intracellular Ionic Homeostasis explored with a Multimodal Approach combining Epifluorescence and Digital Holographic Microscopy

Pierre Magistretti, Pierre Marquet, Christian Depeursinge, Jonas Kühn, Nicolas Pavillon, Pascal Jourdain, Daniel Boss, Aleksandr Benke

The authors have developed a live-cell multimodality microscope combining epifluorescence with digital holographic microscopy; it has been implemented with a decoupling procedure allowing to separately measure from the quantitative phase important cell par ...
