What does Staphylococcus aureus cause?

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.

What can MRSA lead to?

Methicillin-resistant Staphylococcus aureus (MRSA) Staph bacteria are usually harmless, but they can cause serious infections that can lead to sepsis or death.

What toxins are produced by Staphylococcus aureus?

Amongst the more common toxins secreted by S. aureus are hemolysin, leukotoxin, exfoliative toxin, enterotoxin, and toxic-shock syndrome toxin-1 (TSST-1). Aside from toxins, staphylococcal virulence factors also include enzymes and surface proteins.

Which of the following is typically due to a staphylococcal infection?

Staphylococcus aureus is the most pathogenic; it typically causes skin infections and sometimes pneumonia, endocarditis, and osteomyelitis. It commonly leads to abscess formation. Some strains elaborate toxins that cause gastroenteritis, scalded skin syndrome, and toxic shock syndrome.
