How dangerous is Staphylococcus aureus?
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.
Is Staphylococcus aureus a sexually transmitted disease?
Although S. aureus is not traditionally defined as a sexually-transmitted pathogen, these populations may be united through their increased prevalence of S. aureus carriage at multiple body sites, including the genitals, and may consequently be at elevated risk of infection.
What can kill staphylococcus aureus?
Methicillin-resistant Staphylococcus aureus (MRSA) is highly resistant to treatment with antibiotics. These include oxacillin, flucloxacillin, and dicloxacillin.
Where is Staphylococcus aureus found?
Life History and Characteristics: Staphylococcus aureus is a gram positive bacterium that is usually found in the nasal passages and on the skin of 15 to 40% of healthy humans, but can also survive in a wide variety of locations in the body. This bacterium is spread from person to person or to fomite by direct contact.
Does Staph stay in your body forever?
As a result, the body does not develop long-term immunity and remains vulnerable to that particular staph infection throughout life. While certain staph bacteria cause mild skin infections, other strains of staph bacteria can wreak havoc in the bloodstream and bones, sometimes leading to amputations.
What is the best antibiotic for Staphylococcus aureus?
Some of the antibiotics that have been used to treat staph infections are cefazolin, cefuroxime, cephalexin, nafcillin (Nallpen), oxacillin (Bactocill), dicloxacillin, vancomycin, clindamycin (Cleocin), rifampin, and telavancin (Vibativ). Combinations of antibiotics and other antibiotics can also be used.
How long does it take to cure Staphylococcus aureus?
How long it takes for a staph skin infection to heal depends on the type of infection and whether it’s treated. A boil, for example, may take 10 to 20 days to heal without treatment, but treatment may speed up the healing process. Most styes go away on their own within several days.
How do you know if you have Staphylococcus aureus?
The most common type of staph infection is the boil, a pocket of pus that develops in a hair follicle or oil gland. The skin over the infected area usually becomes red and swollen. If a boil breaks open, it will probably drain pus. Boils occur most often under the arms or around the groin or buttocks.
How long does it take to treat staphylococcus aureus?
Traditionally, prolonged courses (4 to 6 weeks) of intravenous antibiotics have been recommended for Staphylococcus aureus bacteremia, largely because of concerns that infective endocarditis or other complications, such as deep infection foci or metastatic infections, might be present but undiagnosed (1, 2).
What kills staph infection naturally?
Alternative Remedies Some people apply substances with reported antimicrobial properties, such as tea tree oil, apple cider vinegar, coconut oil, eucalyptus essential oil, oregano essential oil, and others to skin infections to help them heal.
Can Staphylococcus aureus be cured?
Antibiotic resistanceStaph bacteria are very adaptable, and many varieties have become resistant to one or more antibiotics. For example, only about 10 percent of today’s staph infections can be cured with penicillin.
Who is most at risk for Staphylococcus aureus?
Populations at risk for Staphylococcus aureus infectionAnyone can develop a staph infection, although certain groups of people are at greater risk, including people with chronic conditions such as diabetes, cancer, vascular disease, eczema, lung disease, and people who inject drugs.
What is Staphylococcus aureus caused by?
Staph infection factsStaph infections may cause disease due to direct infection or due to the production of toxins by the bacteria. Boils, impetigo, food poisoning, cellulitis, and toxic shock syndrome are all examples of diseases that can be caused by Staphylococcus.
