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, ...

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 ...

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 ...

Tracking the signaling cargo of extracellular symbionts into host tissues

Anders Meibom, Julia Marie Jeanne Yvonne Bodin, Stéphanie Kéren Cohen

Animal-microbe symbioses are fundamental to animal physiology but the precise nature of molecular exchange between partners remains largely elusive. The mutualistic association between the Hawaiian bobtail squid, Euprymna scolopes and its luminous bacteriu ...

Tracking the signaling cargo of extracellular symbionts into host tissues

Anders Meibom, Julia Marie Jeanne Yvonne Bodin, Stéphanie Kéren Cohen

Animal-microbe symbioses are fundamental to animal physiology but how and where bacteria interact with their host, remain largely elusive. The mutualistic association between the Hawaiian bobtail squid, Euprymna scolopes and its luminous bacterium Vibrio f ...

Dynamic Persistence of Antibiotic-Stressed Mycobacteria

John McKinney, Neeraj Dhar, François Signorino-Gelo, Katrin Esther Schneider

Exposure of an isogenic bacterial population to a cidal antibiotic typically fails to eliminate a small fraction of refractory cells. Historically, fractional killing has been attributed to infrequently dividing or nondividing "persisters." Using microflui ...

From Luminescent Lanthanide Complexes to Color Reproduction and Optical Document Security with Invisible Luminescent Inks

Julien Alexandre Andres

The present thesis deals with luminescent compounds based on lanthanide complexes that are suitable for color reproduction and optical document security with invisible luminescent inks. This thesis is divided in two distinct fields: chemistry, which produc ...
