In my youth as a dedicated eel and bait fisherman I discovered that icky things can happen by getting scraped going down a basses mouth for the hook and eel or whatever and/or getting sliced opened as I was trying to dislodge a hook while the bass wiggles and shimmys to get free itself.
I use a simple solution. You have to have a touch of sado-masichism in your blood but it works. In season I keep a large (I mean LARGE) bottle of hydrogen peroxide by the kitchen sink with a small scrub brush with stiff bristles.
Upon returning home I go to the sink and under luke warm water I scrub any wound until it is open and bleeding again. Sometimes this is many abrasions and cuts if the fishing was good. Then I pour the HP all over it and let it foam away. The pain goes away ( actually just kind of subsides a little) in about 20 minutes and voila, no sh!t growing in there.
I also keep a real good first aid kit in the truck and skiff and if the bleeding is good I treat it right away. After being spined in the hands, knees and leg and having to deal with that infection I take no chances and yes I wear fingerless gloves.
