MRSA (Methicillin Resistant Staphylococcus Aureus)


MRSA (methicillin-resistant Staphylococcus aureus) is a strain of staph bacteria that can cause infection. Staph bacteria are normal on your skin and in your nose. They do not usually cause infection. The bacteria can cause an infection if they get inside your body through a break in your skin. Usually, antibiotics are used to kill bacteria. MRSA bacteria are resistant to the common antibiotics used to treat Staph infections. MRSA infections are most common as skin infections. You can also have MRSA bacteria in your blood, lungs, heart, and bone.

  • Blood and urine tests may be done to see if MRSA bacteria are inside of your body.
  • Wound or mucus cultures may be done to find the bacteria causing your infection. The results may show healthcare providers what medicines will treat your infection.
  • A chest x-ray is a picture of your lungs and heart. The x-ray will show if your infection has spread to your lungs. It may also show abnormal changes to the area around your heart.


  • IV antibiotics that are effective against your MRSA infection may be given. You may need to continue antibiotics after you are discharged from the hospital.


  • Incision and drainage of boils, sores, or an abscess may be done to open and drain infected fluid and pus. The fluid causes bacteria to stay in your wound and keeps it from healing.


MRSA infection can destroy deeper skin layers and tissues. The infection may spread to other parts of your body through your blood. MRSA may lead to infection of your lungs (pneumonia). You may develop a bone infection or an infection in your heart. These infections can become life-threatening.
