MRSA is a Staphyloccus and it is not a Streptococcus. They can look somewhat similar on the body sometimes, (but not on a petri dish!). MRSA is Methicillin Resistant Staphylococcus aureus (MRSA). It is called that because this type of Staph is resistant to methicillin plus several other antibiotics. So it is harder to treat because there are less antibiotics available to treat it with. That doesn't mean they don't have any. They have developed other antibiotics to treat it. However, they are stronger antibiotics and can be harder to take. Staph in general (MRSA or not) causes boils, impetigo, furuncles and mostly other skin and wound problems. Sometimes eye infections and other issues. Sometimes with impetigo you can get a mixture of staph and strep in the wound and you get a crusty sore which is easily spread. It also can produce blisters at first then become crusty. What does your infection look like? Be careful not to touch it without washing your hands and anything you touched wipe down surfaces and the water handle etc. with disinfectant wipes. Wash towels and washrags if you used them after touching the wound or sore. Don't share towels. If you think you have this you can try a triple antibiotic ointment like Neosporin or a generic version. If this doesn't work see your doctor. Boils are another matter. You don't want to open these yourself. You can put a hot clean washrag on them to ease the pain then wash the washrag. Don't scrub them just lay the hot wash rag on the boil. Gently remove it. If it doesn't go down you need to see a doctor. Staph or MRSA can get in the blood stream if you have an open wound. So, you don't want this happen. Let me know your circumstances.
take care.
It is strep, but it is a strep that is resistant to methicillin.
