Abstract

Listeria monocytogenes is a gram-positive bacillus that is commonly associated with foodborne illness. It is a facultative intracellular pathogen responsible for causing the listeriosis infection in humans which is particularly dangerous to immunocompromised individuals. L. monocytogenes pathogenesis occurs through a series of complex interactions between host and bacterial cellular machinery. The wild-type strain as well as a cardiotropic strain with high affinity for infecting cardiac tissue were used to investigate pathogenesis in L. monocytogenes. Specifically, the Listeriolysin O protein that is critical for virulence was investigated. Aerobic and anaerobic growth environments as well as short-chain fatty acid supplementation were utilized to understand how growth conditions affect the pathogenic ability of L. monocytogenes.
