Of all the “superbugs” that can infect you, the one you’re most likely to get outside of a hospital setting is community-acquired MRSA (pronounced mer’-suh). The official name is methicillin-resistant Staphylococcus aureus. I see it in the office fairly often, and it’s resistant to the antibiotics we commonly use for staph.
For cases where you can’t get to a doctor, everyone should know how to treat MRSA.
MRSA is just plain old staph that has adapted with the times. It’s a mutated strain of that same staph aureus that gave you impetigo as a child. As is often the case with superbugs, it was a matter of survival of the fittest.
Every time antibiotics are given, there’s a chance a few bacteria that have mutated a resistance to the antibiotic survive. Then, with no competition (remember, the weaker bacteria were killed), they have room to multiply. Do this a few million times and the strongest survivors develop their own strain.
Staph aureus is a bacteria famous for its adapting capabilities. Penicillin hadn’t been in use very long before staph developed resistance to the degree that we had to develop new types of penicillin (methicillin and oxacillin) to kill it. Cephalexin and erythromycin also worked. But now there’s a strain called MRSA that’s resistant to methicillin, oxacillin, and most other of the common antibiotics.

How to Treat MRSA
Well, that depends on whether it’s the hospital type or the community-acquired type.
MRSA first popped up in the hospital and it’s still a killer there. It can cause wound infections, kidney infections, and pneumonia, to name a few. Only the strongest intravenous antibiotics have any chance at all to get rid of it. Some of the so-called flesh-eating bacteria cases are caused by MRSA.
Fortunately, the one I see in the office is what we call the community-acquired type, and for now, it’s easier to treat. It’s a skin infection and often starts as a pimple that develops into a boil. Many patients come in actually thinking it’s a spider bite but don’t remember seeing a spider.
How to Treat Community-Acquired MRSA
- Antibiotics include the sulfa drug Septra, also known as Bactrim. Clindamycin also works, as does the prescription antibiotic cream, mupirocin (Bactroban). Sooner or later, I’m sure, community-acquired MRSA will become resistant to all of these.
- If it’s an abscess (boil), it needs to be drained. If the boil starts draining, either on its own or with an incision and drainage, the infection will often go away even without antibiotics. If you just can’t get to a doctor for days, read my post about how to lance a boil.
- Honey can kill it. Preferably the Manuka or Medihoney kind. See my post.
- Tea tree oil has also been shown to work.
How to Prevent Community-Acquired MRSA
MRSA is very contagious through contact. To keep from getting it:
- Keep the area bandaged.
- Throw away or sterilize all instruments used.
- Wipe down any exposed areas with a ten percent bleach solution.
- Hand washing is essential.
One more thing. MRSA is found inside the nostrils of a lot of people who don’t have symptoms, so if you’ve been around someone with the infection, consider coating your nostrils with the antibiotic cream mupirocin once a day for a few days. You’ll need to have you doctor give you a prescription for it.
