Adhesion of Is Increased in Association with Foodborne Bacteria.

The aim of this study was to evaluate NTCT 11168 adhesion to abiotic and biotic surfaces when grown in co-culture with ATCC 11229 and/or 4b. Adhesion of C. jejuni to polystyrene and to Caco-2 cells and castellanii was lower for at least 3 log CFU/mL compared to E. coli and L. monocytogenes. Electron micrographs of ultrathin sections revealed interactions of with host cells. In co-culture with and , adhesion of C. jejuni to all tested surfaces was significantly increased for more than 1 log CFU/mL. There was 10% higher aggregation for than for other pathogens, and high co-aggregation of co-cultures of C. jejuni with and . These data show that in co-cultures with and present significantly higher risk than as mono-cultures, which need to be taken into account in risk evaluation. adhesion is a prerequisite for their colonization, biofilm formation, and further contamination of the environment. survival under adverse conditions as a factor in their pathogenicity and depends on their adhesion to different surfaces, not only as individual strains, but also in co-cultures with other bacteria like and .
