Toxic shock syndrome (TSS) is a condition caused by bacterial toxins. [1] Symptoms may include fever , rash , skin peeling , and low blood pressure . [ 1 ] There may also be symptoms related to the specific underlying infection such as mastitis , osteomyelitis , necrotising fasciitis , or pneumonia .
Toxic shock syndrome toxin-1 (TSST-1) is a superantigen with a size of 22 kDa [1] produced by 5 to 25% of Staphylococcus aureus isolates. It causes toxic shock syndrome (TSS) by stimulating the release of large amounts of interleukin-1, interleukin-2 and tumor necrosis factor.
It causes a major inflammatory response in the host via superantigenic properties, and is the causative agent of toxic shock syndrome. It functions as a superantigen through activation of a significant fraction of T-cells (up to 20%) by cross-linking MHC class II molecules with T-cell receptors .

The best-characterized superantigens are those produced by the strains of Staphylococcus aureus and Streptococcus pyogenes that cause toxic shock syndrome. Superantigens bridge the MHC class II protein on antigen-presenting cells with the T-cell receptor on the surface of T cells with a particular Vβ chain.
At Baptist Integris Hospital he was diagnosed with streptococcal toxic shock syndrome – a rare, but very serious, ... "Seeing them cry, I am like, 'Don't, cause you're going to make me cry.' And ...
In streptococcal toxic shock syndrome (StrepTSS), speA produced by infected streptococcal strains acts as a superantigen and interacts with human monocytes and T lymphocytes, inducing T-cell proliferation and production of monokines (e.g. tumor necrosis factor α, interleukin 1, interleukin 6), and lymphokines (e.g. tumor necrosis factor β ...
