Interactions between pili affect the outcome of bacterial competition driven by the type VI secretion system

Melanie Blokesch, Anne-Florence Raphaëlle Bitbol, Alexandre Lemopoulos, Richard Marie Servajean, Simon Bernhard Otto

The bacterial type VI secretion system (T6SS) is a widespread, kin-discriminatory weapon capable of shaping microbial communities. Due to the system’s dependency on contact, cellular interactions can lead to either competition or kin protection. Cell-to-ce ...

Host-derived organic acids enable gut colonization of the honey bee symbiont Snodgrassella alvi

Anders Meibom, Stéphane Laurent Escrig

Diverse bacteria can colonize the animal gut using dietary nutrients or by engaging in microbial crossfeeding interactions. Less is known about the role of host-derived nutrients in enabling gut bacterial colonization. Here we examined metabolic interactio ...

Aptamer-functionalized capacitive biosensors

Nako Nakatsuka

The growing use of aptamers as target recognition elements in label-free biosensing necessitates corresponding transducers that can be used in relevant environments. While popular in many fields, capacitive sensors have seen relatively little, but growing ...

Recent advances in therapeutic targets identification and development of treatment strategies towards Pseudomonas aeruginosa infections

Grazia Vizzarro

The opportunistic human pathogen Pseudomonas aeruginosa is the causal agent of a wide variety of infections. This non-fermentative Gram-negative bacillus can colonize zones where the skin barrier is weakened, such as wounds or burns. It also causes infecti ...

Material Substrate Physical Properties Control Pseudomonas aeruginosa Biofilm Architecture

Alexandre Louis André Persat, Alice Cont

The biofilm lifestyle is the most widespread survival strategy in the bacterial world. Pseudomonas aeruginosa biofilms cause chronic infections and are highly recalcitrant to antimicrobials. The genetic requirements allowing P. aeruginosa to grow into biof ...

Biofilm formation on human immune cells is a multicellular predation strategy of Vibrio cholerae

Alexandre Louis André Persat, Sofya Mikhaleva

Biofilm formation is generally recognized as a bacterial defense mechanism against environmental threats, including antibiotics, bacteriophages, and leukocytes of the human immune system. Here, we show that for the human pathogen Vibrio cholerae, biofilm f ...

Archaeal type IV pili stabilize Haloferax volcanii biofilms in flow

Alexandre Louis André Persat, Lorenzo Anton-Louis Talà, Pascal Damian Odermatt

Multicellular communities of contiguous cells attached to solid surfaces called biofilms represent a common microbial strategy to improve resilience in adverse environments.1-3 While bacterial biofilms have been under intense investigation, whether archaea ...

Two antagonistic response regulators control Pseudomonas aeruginosa polarization during mechanotaxis

Alexandre Louis André Persat, Lorenzo Anton-Louis Talà, Xavier Jean-Yves Pierrat, Joanne Netter Engel, Marco Julian Kühn

The opportunistic pathogen Pseudomonas aeruginosa adapts to solid surfaces to enhance virulence and infect its host. Type IV pili (T4P), long and thin filaments that power surface-specific twitching motility, allow single cells to sense surfaces and contro ...
