Taillefer et al. show that a bacterial type VI secretion system is lost or attenuated during experimental evolution when it provides no competitive advantage but is maintained in the presence of susce...

Paillat et al. show that Flavobacterium johnsoniae combines type VI and type IX secretion systems with gliding motility to efficiently kill diverse bacterial competitors. They demonstrate that nutrien...

In a preclinical breast cancer metastasis model, the same bacteria strain, when present intracellularly versus extracellularly, exerts opposing effects on tumor immunity by inducing divergent neutroph...

Communications Biology - Bacteroidota use the Type IX secretion system to secrete proteins with a conserved C-terminal domain (CTD) secretion signal domain. Type B CTDs require specific shuttle...

Surprise discovery could pave the way for new treatments against drug-resistant infections.

Applications for European research grants increased in 2025. Scientists say they’re feeling the competition.
