Can Staphylococcus aureus cause bacteremia?
INTRODUCTION Staphylococcus aureus is a leading cause of community-acquired and hospital-acquired bacteremia. Patients with S. aureus bacteremia can develop a broad array of complications that may be difficult to recognize initially and can increase morbidity.
What is Staphylococcus aureus bacteraemia?
SAB is a type of infection often associated with healthcare. It occurs when Staphylococcus aureus bacteria (‘Golden staph’) cause an infection of the bloodstream (bacteraemia). When associated with healthcare procedures, these infections are considered to be potentially preventable.
What is the difference between MRSA and Staphylococcus aureus?
Staphylococcus aureus refers to a bacterium that commonly grows on the skin. If this bacterium grows out of control, a person may develop a staph infection. Methicillin-resistant Staphylococcus aureus (MRSA) causes one type of staph infection that can be difficult to treat due to its antibiotic resistance.
What is the most effective antibiotic against Staphylococcus aureus?
The antibiotics most effective against all S aureus cultures for outpatients were linezolid (100%), trimethoprim sulfamethoxazole (95%) and tetracyclines (94%). Linezolid (100%), trimethoprim sulfamethoxazole (100%) were most effective against MRSA isolates.
How do you get staph bacteremia?
What Causes MSSA Bacteremia? Staph bacteremia occurs when MSSA enters the bloodstream. If you develop a staph infection, it is probably from staph bacteria that you’ve been carrying around for a while. Staph bacteria can also be spread from person to person.
How is Staphylococcus aureus bacteremia treated?
aureus bacteremia should be treated with at least 2 weeks of antibiotic therapy. According to consensus guidelines, patients with uncomplicated S. aureus bacteremia (Box 1) may be treated with 2 weeks of antibiotic therapy. All other patients should be treated with at least 4 weeks of antibiotic therapy.
How did I get Staphylococcus aureus?
S. aureus is most often spread to others by contaminated hands. The skin and mucous membranes are usually an effective barrier against infection. However, if these barriers are breached (e.g., skin damage due to trauma or mucosal damage due to viral infection) S.
What happens if you have Staphylococcus aureus?
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 is S. aureus bacteremia treated?
We recommend vancomycin or daptomycin as first-line therapy for MRSA bacteremia. Patients with uncomplicated S aureus bacteremia should be treated for at least 14 days from the first negative blood culture. Patients with complicated S aureus bacteremia should be treated for 4 to 6 weeks.
How serious is staph infection in blood?
If staph bacteria invade your bloodstream, you may develop a type of infection that affects your entire body. Called sepsis, this infection can lead to septic shock. This is a life-threatening episode when your blood pressure drops to an extremely low level.
How serious is bacteremia?

What is the symptoms of Staphylococcus aureus?
Symptoms include redness, swelling, and pain at the site of infection.
- S. aureus can also cause serious infections such as pneumonia (infection of the lungs) or bacteremia (bloodstream infection).
- If you suspect you may have an infection with S. aureus contact your health care provider.
What causes staph bacteremia?
What organ system does Staphylococcus aureus infect?
Staphylococcus aureus , a Gram-positive bacterium colonizing nares, skin, and the gastrointestinal tract, frequently invades the skin, soft tissues, and bloodstreams of humans. Even with surgical and antibiotic therapy, bloodstream infections are associated with significant mortality.
