Listeria monocytogenes is the causative agent of listeriosis, which is one of the leading causes of death from food-borne pathogens. It is especially harmful in pregnant women, newborns, the elderly, and immunocompromised individuals. An interesting characteristic of Listeria monocytogenes is that it can survive in a wide range of stressful environments, including macrophages that produce reactive oxygen species, high salt environments, refrigerated temperatures, and the low pH of a stomach. These environments typically are harmful to microorganisms since they induce DNA damage or destroy the cell wall. The aim of my laboratory is to understand how Listeria monocytogenes is able to adapt, replicate, and infect in these extreme conditions.
