IL-17 signalling is critical for controlling subcutaneous adipose tissue dynamics and parasite burden during chronic Trypanosoma brucei infection

Population genetics of Glossina palpalis gambiensis in the sleeping sickness focus of Boffa (Guinea) before and after eight years of vector control: no effect of control despite a significant decrease of human exposure to the disease

The study assesses the impact of vector control on Glossina palpalis gambiensis population genetics in Guinea, finding no genetic change despite reduced tsetse density and disease prevalence.

Molecular characterization of extended-spectrum beta-lactamase-producing extra-intestinal pathogenic Escherichia coli isolated in a university teaching hospital Dakar-Senegal

This study characterizes ESBL-producing ExPEC isolates from a hospital in Dakar-Senegal, identifying blaCTX-M and blaOXA-1 as prevalent ESBL genes and highlighting resistance patterns.

Culture and genomic analysis of Symbiopectobacterium purcellii, gen.nov. sp. nov., isolated from the leafhopper Empoasca decipiens

This paper describes the isolation and genomic analysis of a new bacterial symbiont, Symbiopectobacterium purcellii, from the leafhopper Empoasca decipiens, highlighting its unique genomic features and metabolic capabilities.

Disruption of the Pseudomonas aeruginosa Tat system perturbs PQS-dependent quorum sensing and biofilm maturation through loss of the Rieske cytochrome bc1 sub-unit

This study identifies the Pseudomonas aeruginosa Tat pathway's role in PQS-dependent quorum sensing and biofilm maturation by showing that disruption of the Rieske cytochrome bc1 subunit impairs virulence factor production and eDNA release.

NirA is an alternative nitrite reductase from Pseudomonas aeruginosa with potential as an anti-virulence target

This paper identifies PA4130 as a nitrite reductase in Pseudomonas aeruginosa, named NirA, which shows reduced virulence in multiple models and may serve as an anti-virulence target.

Pseudomonas aeruginosa biofilms display carbohydrate ligands for CD206 and CD209 that interfere with their receptor function

This paper identifies CD206 and CD209 as receptors for Pseudomonas aeruginosa biofilm carbohydrates, showing they interfere with receptor function and may modulate immune responses.

The analysis of the role of MexAB-OprM on quorum sensing homeostasis shows that the apparent redundancy of Pseudomonas aeruginosa multidrug efflux pumps allows keeping the robustness and the plasticity of this intercellular signaling network

This study shows that overexpression of MexAB-OprM in Pseudomonas aeruginosa impairs quorum sensing by reducing intracellular octanoate, not by extruding the QS signal, highlighting the distinct mechanisms of efflux pump redundancy.

Cross-kingdom signalling regulates spore germination in the moss Physcomitrella patens

This study shows that AHLs affect spore germination in the moss Physcomitrella patens and that sporophytes are associated with AHL-producing bacteria.
