New strains of the superbug methicillin-resistant Staphylococcus aureus (MRSA) have emerged in the community, causing severe, sometimes fatal infections in otherwise healthy people. These strains, called community-acquired MRSA produce a toxin (Panton-Valentine leukocidin). This project will provide important information about how this toxin promotes disease, and how the immune system responds to the toxin, providing the basis for the development of immunotherapies against this new superbug.
