Investigating Biofilm Formation Mechanisms in Salmonella on Fresh Produce Using TraDIS-Xpress

This study investigates the mechanisms employed by Salmonella to colonise and establish itself on fresh produce at critical timepoints following infection. We established an alfalfa infection model and compared the findings to those obtained from glass surfaces. Our research revealed dynamic changes in the pathways associated with biofilm formation over time, with distinct plant-specific and glass-specific mechanisms for biofilm formation, alongside the identification of shared genes playing pivotal roles in both contexts.
