This study uses RNA-Seq to show that Pseudomonas aeruginosa adjusts its gene expression based on growth medium and competition signals from Burkholderia cenocepacia.

This study investigates how virulence and competitive interactions among bacterial species affect host mortality in polymicrobial infections, finding that the most virulent species determines host survival regardless of combination.

The paper examines 61 QS mutants of Pseudomonas aeruginosa to determine how mutations in the quorum sensing regulon affect virulence and social traits, finding that some mutations lead to loss of function while others modulate network activity.

This study uses single-cell imaging to show that Staphylococcus aureus outcompetes Pseudomonas aeruginosa on surfaces through resource and interference competition.

This study shows that strain background, species frequency, and environmental conditions influence competition between Pseudomonas aeruginosa and Staphylococcus aureus, affecting their co-existence and dominance.

The paper examines trait linkage in natural Pseudomonas communities and finds that positive correlations between social traits are common, with most isolates showing a continuum of social behavior rather than specialized repertoires.

This study shows that spatial structure in non-host environments reduces virulence in Pseudomonas aeruginosa by selecting against secreted virulence factors.

This study shows that re-evolving cooperation is constrained in Pseudomonas aeruginosa, as evolved cheats do not revert to full cooperation even under conditions favoring cooperation.

The paper investigates the physical limits of siderophore sharing between surface-attached Pseudomonas aeruginosa cells, showing that sharing is most effective between nearby cells on soft surfaces.
