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.

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.
