Toxic shock syndrome is caused by which organism?

Toxic shock syndrome is driven by toxins produced by Staphylococcus aureus, especially TSST-1. These toxins act as superantigens, triggering widespread T-cell activation and a massive cytokine release that leads to fever, hypotension, a diffuse rash, and potential organ failure. While Streptococcus pyogenes can cause a toxic shock–like syndrome, the classic and most well-known cause of TSS is Staphylococcus aureus. Pseudomonas aeruginosa and Escherichia coli do not produce the specific superantigen responsible for classic TSS.
