Dr. Martin’s research interests include an understanding of how the environment in which a pathogen grows influences its virulence. The bacterium currently under investigation is the foodborne pathogen Listeria monocytogenes. This microorganism can cause serious infection and even death following consumption of contaminated food. Several enzymes have been identified as being important in listerial virulence: listeriolysin O, phospholipase C, catalase and superoxide dismutase. Dr. Martin’s laboratory group has found that the growth environment influences the amounts of these enzymes produced, and is currently examining flagella formation in this bacterium.
