What is the cure for Staphylococcus aureus infection?

The treatment of choice for S. aureus infection is penicillin. In most countries, S. aureus strains have developed a resistance to penicillin due to production of an enzyme by the bacteria called penicillinase.

What is a colonized staph infection?

When staph is present on or in the body without causing illness, it is called colonization. Because staph is so often present on skin, it is the leading cause of skin and soft tissue infections. Twenty percent of the population is colonized with S.

What antibiotic kills Staphylococcus aureus?

Rifampin and ciprofloxacin have been shown to be the most effective intraphagocytic killing agents, while clindamycin and erythromycin were inactive in these in vitro assays.

Is staph aureus positive?

Staphylococcus aureus is the most dangerous of all of the many common staphylococcal bacteria. These gram-positive, sphere-shaped (coccal) bacteria (see figure How Bacteria Shape Up) often cause skin infections but can cause pneumonia, heart valve infections, and bone infections.

Can you get over a staph infection without antibiotics?

Most of the time, minor staph infections can be successfully eliminated. But serious cases may require powerful medicines. Most of the time, minor staph infections can be successfully eliminated.

What are the genes of Staphylococcus aureus USA300?

Isolates of USA300 usually carry the genes encoding the Panton–Valentine leucocidin and the arginine catabolic mobile element, but rarely carry staphylococcal enterotoxin genes.

What kind of PFGE is USA300 MRSA?

All except USA900 and USA1200 are MRSA. The MRSA PFGE type USA300 emerged within S. aureus MLST clonal complex (CC) 8.

What kind of disease does ST8 USA300 cause?

“ST8:USA300”. ST8:USA300 is a strain of community-associated methicillin-resistant Staphylococcus aureus (MRSA) that has emerged as a particularly antibiotic resistant epidemic that is responsible for rapidly progressive, fatal diseases including necrotizing pneumonia, severe sepsis and necrotizing fasciitis.

When did methicillin resistant Staphylococcus aureus ( MRSA ) emerge?

In the United States, methicillin-resistant Staphylococcus aureus (MRSA) with the USA300 pulsed-field gel electrophoresis type causes most community-associated MRSA infections and is an increasingly common cause of health care–associated MRSA infections. USA300 probably emerged during the early 1990s.
