What is an interesting fact about Staphylococcus aureus?

Interesting Facts: The ‘aureus’ is from its golden colour. Many people carry S. aureus and even antibiotic resistant variants such as Methicillin/Multi resistant Staphylococcus aureus (MRSA), a superbug, on their skin and mucous membranes. Up to 20% of the human population may be a carrier of this bacteria.

How long can Staphylococcus aureus live?

Methicillin-resistant Staphylococcus aureus (MRSA) can survive on some surfaces, like towels, razors, furniture, and athletic equipment for hours, days, or even weeks. It can spread to people who touch a contaminated surface, and MRSA can cause infections if it gets into a cut, scrape, or open wound.

Where is Staphylococcus aureus most commonly found?

S. aureus is commonly found in the environment (soil, water and air) and is also found in the nose and on the skin of humans. S. aureus is a Gram-positive, non-spore forming spherical bacterium that belongs to the Staphylococcus genus.

What does Staphylococcus aureus live on?

Staphylococcus aureus (S. aureus) is a common bacterium that lives on the skin and in some people’s noses.

What temperature kills staph?

The same degree of destruction is achieved in similarly contaminated foods when held at 140 F for 78 to 83 min. On the basis of the calculation procedures employed, it is estimated that 45-min exposure at 140 F would be necessary to reduce 1,000 organisms per gram to nondetectable levels.

What does Staphylococcus aureus do?

It is the leading cause of skin and soft tissue infections such as abscesses (boils), furuncles, and cellulitis. Although most staph infections are not serious, S. aureus can cause serious infections such as bloodstream infections, pneumonia, or bone and joint infections.

How does Staphylococcus aureus grow?

S. aureus is a facultative anaerobe that grows by aerobic respiration or by fermentation, which yields principally lactic acid. The bacterium metabolizes glucose via the pentose phosphate pathway (Reizer et al., 1998).

What does Staphylococcus aureus eat?

“Staph” bacteria feed on blood. They need the iron that’s hidden away inside red blood cells to grow and cause infections.

Is Staphylococcus aureus helpful?

aureus has a beneficial effect on EAE, indicating a dual role of infection in the pathogenesis of MS. We also showed that secretion of Eap by S. aureus plays a major role in preventing autoimmune inflammation of the CNS. Moreover, we identified Eap as a factor responsible for this protective effect.

How fast does Staphylococcus aureus grow?

S. aureus grows rapidly in rich medium (doubling time 20 min) and yields a yellow colony on plate owing to the production of the carotenoid pigment staphyloxanthin.
