  • Description: <jats:title>Significance</jats:title> <jats:p> Comparative analysis of multiple strains within a species is a powerful way to uncover pathoadaptive genetic acquisitions. Hundreds of genome sequences are now available for the human pathogen <jats:italic>Staphylococcus aureus,</jats:italic> mostly known for its antibiotic-resistant variants that threaten the emergence of panresistant superbugs. In this study, genome-scale models of metabolism are used to analyze the shared and unique metabolic capabilities of this pathogen and its strain-specific variants. The models are used to distinguish <jats:italic>S. aureus</jats:italic> strains responsible for severe infections based solely on growth capabilities and presence of different virulence factors. The results identify metabolic similarities and differences between <jats:italic>S. aureus</jats:italic> strains that provide insights into the epidemiology of <jats:italic>S. aureus</jats:italic> and may help to combat its spread. </jats:p>
