What toxin causes toxic shock syndrome?

What toxin causes toxic shock syndrome?

Bacteriology. Toxic shock syndrome (TSS) is caused from intoxication by one of several related Staphylococcus aureus exotoxins. The most commonly implicated toxins include TSS toxin type-1 (TSST-1) and Staphylococcal enterotoxin B.

Which type of contraception is associated with toxic shock syndrome?

Two birth control methods, the contraceptive sponge and the diaphragm, have been linked to TSS. Toxic shock syndrome also can affect someone with any type of staph infection, including: pneumonia.

What is the mechanism of action for the toxic shock syndrome toxin?

Toxic shock syndrome toxin 1 (TSST-1), a prototype superantigen secreted by a Staphylococcus aureus bacterium strain in susceptible hosts, acts on the vascular system by causing inflammation, fever, and shock.

What is Septicaemia and toxic shock syndrome?

Septic shock and toxic shock syndrome (TSS) in children are both related to bacterial infections. Whereas septic shock follows an overwhelming immune response to the infection, TSS is the result of exotoxins of the bacteria themselves.

What is the pathophysiology of toxic shock syndrome?

Toxic shock syndrome (TSS) is caused from intoxication by one of several related Staphylococcus aureus exotoxins. The most commonly implicated toxins include TSS toxin type-1 (TSST-1) and Staphylococcal enterotoxin B. Almost all cases of menstrual TSS and half of all the nonmenstrual cases are caused by TSST-1.

When can toxic shock syndrome occur?

In general, TSS symptoms can develop as soon as 12 hours after a surgical procedure. Symptoms usually develop in 3 to 5 days in women who are menstruating and using tampons. If you experience the above symptoms after using tampons or after a surgery or skin injury, contact your health care provider immediately.

What is toxic shock syndrome and what are its symptoms?

Toxic shock syndrome (TSS) is a cluster of symptoms that involves many systems of the body. Certain bacterial infections release toxins into the bloodstream, which then spreads the toxins to body organs. This can cause severe damage and illness.

What is the meaning of toxic shock syndrome?

Toxic shock syndrome is a sudden, potentially fatal condition. It’s caused by the release of toxins from an overgrowth of bacteria called Staphylococcus aureus, or staph, which is found in many women’s bodies. Toxic shock syndrome affects menstruating women, especially those who use super-absorbent tampons.

Why does tampons cause toxic shock syndrome?

Tampons (especially super-absorbent varieties) that are left in the vagina for a long time may encourage the bacteria to grow. Tampons can stick to the vaginal walls, especially when blood flow is light, causing tiny abrasions when they are removed.

What are the long term effects of toxic shock syndrome?

Most patients make a full recovery, but since TSS is rare, there is little information about the long-term effects. There have been reports of persistent muscle weakness and psychological effects, such as difficulty concentrating, memory loss, and emotional changes.
