Dr. Cheung's major research interests are regulation of virulence gene in Staphylococcus aureus, a major human pathogen both in the community and in hospital settings. My lab has four separate but related directions: 1) regulation of virulence determinants by global regulatory in S. aureus; 2) expression of virulence genes in vivo; 3) development of novel targets for antimicrobial therapy; 4) role of sRNA in virulence in S. aureus.
The stringent response contributes to persistent methicillin-resistant Staphylococcus aureus endovascular infection through the purine biosynthetic pathway.
