Question: are all skin boils mrsa?
Answer: Image courtesy of CDC/Bruno Coignard, M.D.; Jeff Hageman, M.H.S. Even though MRSA most often shows up as blisters or boils, not all blisters or boils are from MRSA. Other forms of Staphylococcus aureus, as well as group A Streptococcus bacteria, cause skin infections that look very similar.
