Clinical Information

  • Infections with bacteria of the genus staphylococcus.
  • Infections with bacteria of the genus staphylococcus; includes staphylococcal pneumonia, staph skin infections, furunculosis, carbuncle, impetigo, ritter disease, scalded skin syndrome, etc.
  • Staph is short for staphylococcus, a type of bacteria. There are over 30 types, but staphylococcus aureus causes most staph infections (pronounced “staff infections”), including
    • skin infections
    • pneumonia
    • food poisoning
    • toxic shock syndrome
    • blood poisoning (bacteremia)
    skin infections are the most common. They can look like pimples or boils. They may be red, swollen and painful, and sometimes have pus or other drainage. They can turn into impetigo, which turns into a crust on the skin, or cellulitis, a swollen, red area of skin that feels hot.anyone can get a staph skin infection. You are more likely to get one if you have a cut or scratch, or have contact with a person or surface that has staph bacteria. The best way to prevent staph is to keep hands and wounds clean. Most staph skin infections are easily treated with antibiotics or by draining the infection. Some staph bacteria such as mrsa (methicillin-resistant staphylococcus aureus) are resistant to certain antibiotics, making infections harder to treat.
