Methicillin-resistant Staphylococcus aureus ( MRSA ) is a serious bacterial infection that is resistant to standard antibiotic treatment. It often causes mild, blistering sores on the skin.

Sometimes MRSA causes serious infections. In these cases, it can spread through the bloodstream and infect other organs, such as the lungs or urinary tract.

Symptoms of an MRSA infection depend on the part of the body infected and can include redness, swelling, pain, pus, or fever. Some MRSA infections look like other bacterial skin infections and can even be mistaken for a spider bite.

Laboratory tests are usually required to accurately diagnose MRSA. If left untreated, MRSA can be easily passed from person to person and can become infected in the hospital after surgery.


Bacterial skin infections are common and difficult to differentiate. While most of them are not dangerous, they need treatment, and some can lead to serious and even life-threatening complications.

If you notice that in your opinion there may be a skin infection in yourself or a loved one, be sure to see a doctor for the correct diagnosis and treatment.
