I seem to have caused the concern, and I never wear gloves. If I have an open cut on my hands, tank work can wait til it scabs over. I really don't think I would have caught Myco marinum if I hadn't been in a state of exhaustion and high stress - I was in a very extreme situation stress wise. I had kids, two jobs and was caring for a dying close family member. I cut sleep radically, and that's when I encountered the pathogen.
The other person I knew who caught it was a hardcore drug user working in a pet store. She was a wreck.
Then again, I respect a doctor being cautious, and maybe there's something there. But I wouldn't be caught dead wearing gloves that ugly!
I mentioned I had had this to a local doctor, and she said she was surprised to learn I'd been a deep sea scuba diver. Nope. So they get it too.
