Staphylococci bacteria are commonly found living on the skin and in the noses of humans, often causing no adverse affects. Many different strains of the bacteria exist, but Staphylococcus aureus---also known as staph---is the one usually responsible for causing infection. Skin infections are the most common, although the staph bacteria can infect other organs as well.
Significance
Almost everyone has a strain of staph bacteria living on their skin or in their bodies right now. Most of the time, this causes no problems, as the immune system keeps the bacteria at bay. The bacteria are a hardy breed and can be spread either from person to person or via contaminated pillowcases or towels. Staph bacteria can survive extreme temperatures, high levels of salt and even cooking.
Infections
The most common skin infections caused by staph bacteria are boils and abscesses. Boils occur when a hair follicle becomes infected with staph bacteria, and often becomes red and tender. An abscess develops when a cavity fills with pus, which can result from a large boil or other injury. A contagious and painful rash called impetigo can also develop from staph bacteria, and features large blisters that ooze and crust over.
Diagnosis
Many skin infections and conditions look very similar, so your doctor will most likely order a test to determine the exact cause of your infection. A sample or swab of the infected area can be tested for the presence of staph bacteria. A blood sample may also be used to determine the source of your infection.
Treatment
Some varieties of staph bacteria have become resistant to certain antibiotics, so it's important to identify the specific bacteria causing the infection to ensure proper treatment. For some infections, a simple round of antibiotics will clear things up, while for others, a stronger antibiotic---or a number of them---may help.
Prevention/Solution
The best way to avoid developing any infections from staph bacteria is to observe proper hygiene procedures, such as regular hand washing. Keep any wounds covered with clean, dry bandages until they heal. Do not share personal items, such as razors or towels; also, wash towels and linens in hot water with detergent and bleach.
