耐甲氧西林金黄色葡萄球菌检测
California state law requires hospitals to test some patients for a germ called methicillin-resistant 金黄色葡萄球菌, 或耐甲氧西林金黄色葡萄球菌. If you're admitted to the hospital at UCSF Medical Center for surgery and you're considered susceptible f或耐甲氧西林金黄色葡萄球菌 infection, you will be tested for this germ.
金黄色葡萄球菌, pronounced staff-ill-oh-KOK-us AW-ree-us, or "staph" are a common bacteria. MRSA is a type of staph that isn't killed by penicillin or similar antibiotics, the drugs most commonly used to treat staph infections. It is resistant to many antibiotics, making it more difficult to treat.
About one out of every three people has staph on his or her skin or in the nose without it causing any problem, and about one out of every 100 people carry MRSA without getting sick. However, in some cases staph 或耐甲氧西林金黄色葡萄球菌 can cause an infection. An infection may look like any of the following:
- Sores that look and feel like spider bites
- Red, painful bumps under the skin
- Swollen, hot pus-filled cut
- Blisters filled with fluid or red skin with a honey-colored crust, usually on the face
- Area of red, warm firm skin that's painful and gets larger, usually on the legs
Infections caused by MRSA don't look any different from infections caused by ordinary staph.
What your test results mean
