BatR: A novel regulator of antibiotic tolerance in Pseudomonas aeruginosa biofilms

This study identifies PA3049, renamed BatR, as a key regulator of antibiotic tolerance in Pseudomonas aeruginosa biofilms, showing its role in stress response and antimicrobial resistance.

Investigating how Salmonella colonise alfalfa using a whole genome screen.

This study uses a whole genome screen to identify genes involved in Salmonella biofilm formation on alfalfa and glass surfaces, revealing distinct mechanisms for each.

Common food preservatives impose distinct selective pressures on Salmonella Typhimurium planktonic and biofilm populations

This study shows how four food preservatives exert distinct selective pressures on Salmonella Typhimurium planktonic and biofilm populations, leading to mutations in stress response regulators and trade-offs between biofilm formation and growth.

Efflux only impacts drug accumulation in actively growing cells

This study shows that efflux pumps only limit drug accumulation in actively growing cells, while envelope permeability is the main factor in stationary phase.

Antibiotics select for novel pathways of resistance in biofilms

This study shows biofilms of Salmonella Typhimurium rapidly evolve resistance to antibiotics through novel mechanisms, with fitness costs associated with adaptation.

Increased usage of antiseptics is associated with reduced susceptibility in clinical isolates of S. aureus

This study shows increased chlorhexidine use in hospitals correlates with higher resistance in S. aureus isolates, while octenidine resistance was less common and not linked to cross-resistance.
