Dataset Summary
TitlePathogen-pathogen interactions in the microbiome, a way to soothe virulence?
DescriptionThe rise of multi-drug resistance in bacterial pathogens imposes the need to study these organisms from new angles. A little explored outset is to scrutinize bacterial niche adaptations and interactions among pathogenic and commensal bacteria, because they can provide a better understanding of the fitness of pathogens in their human host. We have previously shown that co-culturing of the pathogen Staphylococcus aureus with co-resident Klebsiella oxytoca or Bacillus thuringiensis wound isolates resulted in reduced levels of virulence factor secretion, suggesting that the presence of these co-resident bacteria would modulate S. aureus virulence. In the present study, we performed an in-depth investigation of changes in S. aureus gene expression upon co-cultivation with K. oxytoca and B. thuringiensis under infection-mimicking conditions. To this end, we profiled the cellular proteomes of the co-existing bacteria with special focus on S. aureus. In parallel, we employed RNA sequencing to highlight global changes in staphylococcal behaviour. The results imply that co-colonizing bacteria from chronic wounds can pacify S. aureus, and this conclusion was verified in a Galleria mellonella infection model. Altogether, our findings show that the presence of K. oxytoca and B. thuringiensis leads to massive rearrangements in S. aureus physiology and substantial reduction in virulence.
