Population genetics and the evolution of virulence in Staphylococcus aureus
Abstract
Staphylococcus aureus is one of the most important human pathogens, causing life-threatening infection in the community and hospital setting. The population genetics of S. aureus and the evolution of virulence is the focus of this review. We describe the various techniques in determining S. aureus population structure and discuss the insights gained from whole genome sequencing of various S. aureus strains. The emergence of community-acquired, methicillin-resistant S. aureus provides a framework for the discussion on evolution of virulence, and the role of horizontal gene transfer in the development of virulence and antibiotic resistance is explored. The knowledge generated from population genetics has the potential to inform strategies to assist in the prevention or treatment of this highly successful human pathogen.
Keywords: Methicillin-resistant S. aureus; Molecular epidemiology; Multi-locus sequence typing; S. aureus.
