From what I have heard it is a Staff bacteria resistant to most antibiotics
I know a couple of friends who have had troubles with it. NOT something to be ignored.
I have heard that the alchohol in these hand sanitizers will kill it and that rubbing alchohol will kill it also. some guys carry rubbing alchohol in a pump sprayer and spritz off after wading. But! don't smoke or you may get a hot surprize!
Personally I carry some hand sanitizer in my tackle box in case I get stuck by a hook, finned , etc.
usually every trip. Always treat any wound or sore immediately, and don't wade fish with open, or scabbed over sores. wear waders if needed. If you get a sore that gets worse rapidly, get to a doctor pronto. MRSA infections get bad quick and take IV antibiotics to stop. Also a couple of good shots of the hand sanitizer "Purell" etc. makes a good hand cleaner.
