What Causes Staph Infections, and How Can You Avoid Them?
Oct 24, · The staphylococcus bacteria, which is all around us, causes staph infections. Find out more about types of staph infections and when they’re cause for worry. Sep 09, · A staph infection is caused by the bacteria Staphylococcus aureus. Staph can cause boils, food poisoning, cellulitis, toxic shock syndrome, MRSA, and various other illnesses and infections. Most staph infections are transmitted from person to person.
Staph infections are caused by staphylococcus bacteria, types of germs commonly found on the skin or in the nose of even healthy individuals. Most of the time, these bacteria cause no problems or result in relatively minor skin infections. But staph infections can turn deadly if the bacteria invade deeper into your body, entering your bloodstream, joints, bones, lungs or heart. A growing number of otherwise healthy people are developing life-threatening staph infections.
Treatment usually involves antibiotics and drainage of the infected area. However, some staph infections no longer respond to common antibiotics. MRSA infections start out as small red bumps that can quickly turn into deep, painful abscesses.
Staph infections can range from minor skin problems to endocarditis, a life-threatening infection of the inner lining of your heart endocardium. Because of this, signs and symptoms of staph infections vary widely, depending on the location and how to copy a song onto a cd of the infection. 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.
Staph bacteria are one of the most common causes of food poisoning. Symptoms come on quickly, usually within hours of eating a contaminated food.
Symptoms usually disappear quickly, too, often lasting just half a day. A staph infection in food usually doesn't cause a fever. Signs and symptoms you can expect with this type of staph infection include:.
Also known as a bloodstream infection, bacteremia occurs when staph bacteria enter a person's bloodstream. A fever and low blood pressure are signs of bacteremia. The bacteria can travel to locations deep within your body, to produce infections affecting:. This life-threatening condition results from toxins produced by some strains of staph bacteria and has been linked to certain types of tampons, skin wounds and surgery. It usually develops suddenly with:.
Septic arthritis is often caused by a staph infection. The bacteria often target the knees, shoulders, hips, and fingers or toes. Signs and symptoms may include:. Many people carry staph bacteria and never develop staph infections.
However, if you develop a staph infection, there's a good chance that it's from bacteria you've been carrying around for some time. These bacteria can also be transmitted from person to person. Because staph bacteria are so hardy, they can live on objects such as pillowcases or towels long enough to transfer to the what food did knights eat in the middle ages person who touches them.
A variety of factors — including the status of your immune system to the types of sports you play — can increase your risk of developing staph infections. Certain disorders or the medications used to treat them can make you more susceptible to staph infections.
People who may be more likely to get a staph infection include those with:. Despite vigorous attempts to eradicate them, staph bacteria remain present in hospitals, where they attack the most vulnerable, including people with:.
Staph bacteria can travel along the medical tubing that connects the outside world with your internal organs. Examples include:. Staph bacteria can spread easily through cuts, abrasions and skin-to-skin contact.
Staph infections may also spread in the locker room through shared razors, towels, uniforms or equipment. Food handlers who don't properly wash their hands can transfer staph from their skin to the food they're preparing.
Foods that are contaminated with staph look and taste normal. 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 — a life-threatening episode with extremely low blood pressure.
Wash your hands. Careful hand-washing is your best defense against germs. Wash your hands with soap and water briskly for at least 20 seconds. Then dry them with a disposable towel and use another towel to turn off the faucet.
If your hands aren't visibly dirty, you can use an alcohol-based hand sanitizer. Wash your hands with soap and water regularly, such as before, during and after making food; after handling raw meat or poultry; before eating; after using the bathroom; and after touching an animal or animal waste.
Wash clothing and bedding in hot water. Staph bacteria can survive on clothing and bedding that isn't properly washed. To get bacteria off clothing and sheets, wash them in hot water whenever possible. Also, use bleach on any bleach-safe materials. Drying in the dryer is better than air-drying, but staph bacteria may survive the clothes dryer.

Feb 12, · Staph 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.

Dec 04, · According to Mayo Clinic, the most common cause of a sore throat is a virus. Although far less common, bacteria can cause some sore throats (bacterial pharyngitis).Author: Jacob Clarke.
Methicillin-resistant Staphylococcus aureus MRSA infection is caused by a type of staph bacteria that's become resistant to many of the antibiotics used to treat ordinary staph infections. Most MRSA infections occur in people who've been in hospitals or other health care settings, such as nursing homes and dialysis centers. HA-MRSA infections usually are associated with invasive procedures or devices, such as surgeries, intravenous tubing or artificial joints. HA-MRSA can spread by health care workers touching people with unclean hands or people touching unclean surfaces.
Another type of MRSA infection has occurred in the wider community — among healthy people. It's usually spread by skin-to-skin contact. At-risk populations include groups such as high school wrestlers, child care workers and people who live in crowded conditions. MRSA infections start out as small red bumps that can quickly turn into deep, painful abscesses. Staph skin infections, including MRSA , generally start as swollen, painful red bumps that might look like pimples or spider bites.
The affected area might be:. These red bumps can quickly turn into deep, painful boils abscesses that require surgical draining. Sometimes the bacteria remain confined to the skin. But they can also burrow deep into the body, causing potentially life-threatening infections in bones, joints, surgical wounds, the bloodstream, heart valves and lungs.
Keep an eye on minor skin problems — pimples, insect bites, cuts and scrapes — especially in children. If wounds appear infected or are accompanied by a fever, see your doctor.
Different varieties of Staphylococcus aureus bacteria, commonly called "staph," exist. Staph bacteria are normally found on the skin or in the nose of about one-third of the population.
The bacteria are generally harmless unless they enter the body through a cut or other wound, and even then they usually cause only minor skin problems in healthy people.
MRSA is the result of decades of often unnecessary antibiotic use. For years, antibiotics have been prescribed for colds, flu and other viral infections that don't respond to these drugs. Even when antibiotics are used appropriately, they contribute to the rise of drug-resistant bacteria because they don't destroy every germ they target.
Bacteria live on an evolutionary fast track, so germs that survive treatment with one antibiotic soon learn to resist others. Because hospital and community strains of MRSA generally occur in different settings, the risk factors for the two strains differ.
MRSA infections can resist the effects of many common antibiotics, so they're more difficult to treat. This can allow the infections to spread and sometimes become life-threatening. MRSA infections may affect your:. Visitors and health care workers caring for people in isolation may need to wear protective garments. They also must follow strict hand hygiene procedures. For example, health care workers can help prevent HA-MRSA by washing their hands with soap and water or using hand sanitizer before and after each clinical appointment.
Hospital rooms, surfaces and equipment, as well as laundry items, need to be properly disinfected and cleaned regularly. Mayo Clinic does not endorse companies or products.
