CcpA promotes Staphylococcus aureus virulence by directly controlling staphyloxanthin production

mLife, Volume 4, Issue 6, Page 651-663, December 2025.
Abstract Staphylococcus aureus is a notorious opportunistic pathogen with remarkable adaptability, enabling it to infect virtually every human tissue. Staphyloxanthin (STX), a critical virulence factor, contributes to S. aureus oxidative damage. However, the regulatory mechanism of STX production is incompletely understood.
