how does staphylococcus aureus cause toxic shock syndrome
Toxic shock syndrome TSS is caused by bacteria of either the Streptococcus pyogenes or Staphylococcus aureus type.[1] Streptococcal toxic shock syndrome (STSS) is sometimes referred to as toxic shock-like syndrome (TSLS).[1] The underlying mechanism involves the production of superantigens during an invasive streptococcus infection or a localized staphylococcus infection.[1] Risk factors for the staphylococcal type include the use of very absorbent tampons and skin lesions in young children.[1] Diagnosis is typically based on symptoms.[1]
Staphylococcus aureus Staphylococcus aureus is a Gram-positive, round-shaped bacterium that is a member of the Firmicutes, and it is a member of the normal flora of the body, frequently found in the nose, respiratory tract, and on the skin. It is often positive for catalase and nitrate reduction and is a facultative anaerobe that can grow without the need for oxygen.[1] Although S. aureus is not always pathogenic (and can commonly be found existing as a commensal), it is a common cause of skin infections including abscesses, respiratory infections such as sinusitis, and food poisoning. Pathogenic strains often promote infections by producing virulence factors such as potent protein toxins, and the expression of a cell-surface protein that binds and inactivates antibodies. The emergence of antibiotic-resistant strains of S. aureus such as methicillin-resistant S. aureus (MRSA) is a worldwide problem in clinical medicine. Despite much research and development, no vaccine for S. aureus has been approved.
