Title: Intra- and inter-species interactions within biofilms of important foodborne bacterial pathogens
Issue Date: 2015
Abstract: A community-based sessile life style is the normal mode of growth and survival formany bacterial species. Under such conditions, cell-to-cell interactions are inevitableand ultimately lead to the establishment of dense, complex and highly structuredbiofilm populations encapsulated in a self-produced extracellular matrix and capable ofcoordinated and collective behavior. Remarkably, in food processing environments, avariety of different bacteria may attach to surfaces, survive, grow, and form biofilms.Salmonella enterica, Listeria monocytogenes, Escherichia coli, and Staphylococcusaureus are important bacterial pathogens commonly implicated in outbreaks offoodborne diseases, while all are known to be able to create biofilms on both abioticand biotic surfaces. Particularly challenging is the attempt to understand the complexityof inter-bacterial interactions that can be encountered in such unwanted consortia, suchas competitive and cooperative ones, together with their impact on the final outcomeof these communities (e.g., maturation, physiology, antimicrobial resistance, virulence,dispersal). In this review, up-to-date data on both the intra- and inter-species interactionsencountered in biofilms of these pathogens are presented. A better understandingof these interactions, both at molecular and biophysical levels, could lead to novelintervention strategies for controlling pathogenic biofilm formation in food processingenvironments and thus improve food safety.
