Campylobacter spp. cause food-borne illnesses worldwide due to contaminated food and cross-contamination. This is at least partly the consequence of Campylobacter resistance during the food-production chain, as modern food production facilitates emergence and spread of resistance through intensive use of antimicrobial agents and international trade in raw materials and food products. In additiona, the incidence and prevalence of campylobacteriosis is still increasing, which is mainly associated with consumption of undercooked poultry meat products, and with outbreaks arising from contaminated water. Campylobacter adhesion and biofilm formation has major implications in the food industry, where biofilms can create persistent sources of contamination while conferring survival benefits to Campylobacter through industrial processes and transmission to the next host. Novel strategies are needed to reduce bacterial contamination and to control Campylobacter in foods. In his project we will use Campylobacter as our model to develop novel strategies to combat contamination and infection, through targeting the mechanisms of action that are not sensitive to the ever-increasing repertoire of bacterial resistance mechanisms. The proposed project specifically addresses the issue of understanding the mechanisms by which Campylobacter adhere to surfaces, which is crucial for the application of novel antimicrobial strategies
