Global emergence and evolution of <i>Staphylococcus aureus</i> clonal complex 59

The prevalence and propagation of <i>Staphylococcus aureus</i> clonal complex 59 (CC59) in Asia are serious public health concerns. To understand its adaptation to hosts and worldwide evolutionary success, we analyzed the genomic population structure of all CC59 isolates and traced their evolutionary history. Our research indicates that CC59 lineages developed through unique evolutionary routes that vary across time and space, highlighting their adaptation to diverse ecological environments. This study presents a comprehensive genomic epidemiology framework that integrates extensive metadata analysis with evolutionary assessment. It serves as a model for future <i>S. aureus</i> monitoring and provides insights into potential targets for interventions focused on reducing virulence.
