Molecular Responses to Stress in Food-borne Bacterial Pathogens

Molecular Responses to Stress in Food-borne Bacterial Pathogens

Dr O’Byrne’s research group focuses on two model food-borne bacterial pathogens, Listeria monocytogenes and Escherichia coli. The emphasis of the work is on understanding the mechanisms that allow these organisms sense and respond to environmental stresses. Understanding how pathogenic bacteria sense and respond to changes in their environment is critical if we are to devise rational strategies to prevent their entry into the food chain and to prevent infections from arising in the human population.
