Campylobacterjejuni is the most common cause of bacterial food-borne gastroenteritis in the developed world and is most commonly associated with the consumption of contaminated poultry.To cause disease in humans,Campylobacter must survive both in the food chain and transit within the gastrointestinal tract.This talk focuses on adaptive behaviours used by Campylobacter to survive.In particular,the talk will focus on chemotaxis and biofilm formation and draw a connection between these two adaptive behaviours.Chemotaxis is the ability of an organism to sense the environment and alter swimming accordingly.A model of chemotaxis in C.jejuni is presented and questions arising discussed.Biofilms are surface-adhered communities of bacteria surrounded by an extra-cellular matrix.Insights into biofilm formation by C.jejuni will be discussed in relation to food-grade models and novel interventions.
