A subcellular biochemical model for T6SS dynamics reveals winning competitive strategies

The type VI secretion system (T6SS) is a broadly distributed interbacterial weapon that can be used to eliminate competing bacterial populations. Although unarmed target populations are typically used to study T6SS function in vitro, bacteria most likely e ...

Tracking the cargo of extracellular symbionts into host tissues with correlated electron microscopy and nanoscale secondary ion mass spectrometry imaging

Anders Meibom, Stéphane Laurent Escrig, Stéphanie Kéren Cohen

Extracellular bacterial symbionts communicate biochemically with their hosts to establish niches that foster the partnership. Using quantitative ion microprobe isotopic imaging (nanoscale secondary ion mass spectrometry [NanoSIMS]), we surveyed localizatio ...

Insights into flagellar function and mechanism from the squid-vibrio symbiosis

Stéphanie Kéren Cohen

Flagella are essential and multifunctional nanomachines that not only move symbionts towards their tissue colonization site, but also play multiple roles in communicating with the host. Thus, untangling the activities of flagella in reaching, interacting, ...

Two nanomachines drive evolution in diverse Vibrio species

Noémie Matthey

Horizontal gene transfer (HGT) has a major impact on bacterial evolution, leading to acquisition or deletion of genes and gene clusters, including those encoding antibiotic resistances and virulence factors. HGT therefore contributes to pathogen emergence, ...

Label-free Bacteria Quantification in Blood Plasma by a Bioprinted Microarray Based Interferometric Point-of-Care Device

Hatice Altug, Filiz Yesilköy, Alexander Belushkin

Existing clinical methods for bacteria detection lack speed, sensitivity, and, importantly, point-of-care (PoC) applicability. Thus, finding ways to push the sensitivity of clinical PoC biosensing technologies is crucial. Here we report a portable PoC devi ...

Bacterial type VI secretion system facilitates niche domination

Melanie Blokesch, Natalia Carolina Drebes Dorr

Over the last few decades humanity has experienced a series of tremendous technological advances, especially in the realm of basic science. A plethora of new approaches has allowed us to appreciate life in previously unimaginable detail, prompting the real ...

Eco-Evolutionary Dynamics Linked to Horizontal Gene Transfer in Vibrios

Melanie Blokesch, Frédérique Marie Jeanne Le Roux

Vibrio is a genus of ubiquitous heterotrophic bacteria found in aquatic environments. Although they are a small percentage of the bacteria in these environments, vibrios can predominate during blooms. Vibrios also play important roles in the degradation of ...

Visualizing chemical transport from extracellular symbionts into squid host tissues using NanoSIMS

Stéphanie Kéren Cohen

Chemical communication is the basis of host-microbe interaction. Insights into this communication will provide a deeper understanding of the mechanisms that govern these complex associations, in beneficial as well as pathogenic contexts. In this dissertati ...

Bioluminescence for Assessing Drug Potency against Nonreplicating Mycobacterium tuberculosis

Stewart Cole, Neeraj Dhar, Claudia Sala, Ruben Hartkoorn, Ming Zhang, Benoit Lechartier, Anthony Vocat

Targeting dormant Mycobacterium tuberculosis represents a challenge to antituberculosis drug discovery programs. We previously reported and validated the use of the streptomycin (STR)-dependent M. tuberculosis 18b strain as a tool for assessing drug potenc ...

The emergence of Vibrio pathogens in Europe: ecology, evolution, and pathogenesis (Paris, 11–12th March 2015)

Melanie Blokesch, Frédérique Marie Jeanne Le Roux

Global change has caused a worldwide increase in reports of Vibrio-associated diseases with ecosystem-wide impacts on humans and marine animals. In Europe, higher prevalence of human infections followed regional climatic trends with outbreaks occurring dur ...
