Used to be viruses were the real nasties.
But these days, there's some new little buggers coming down the pipe that are downright rude.
MSRA staph, some other unwelcome types.
I read a bit about resistant organisms once. It talked about some hospital room, I seem to remember Chicago, where this white stuff started growing on the wall.
They tried all sorts of stuff. Straight Clorox type, peroxide, whatever they use. Actually thought they had it killed off a couple times, but it just kept coming back.
The solution was to back up a truck and fill the whole room. With concrete.
Did they try a paste of 20 Mule Team Borax?
Actually, I think the boron atoms inhibit mold, maybe mildew.
And then there was that black growth in Mir that was growing on, or eating the titanium...
Right. It's MRSA, however, not MSRA. Methicillin-resistant Staph Aureus. Big, bad problem. And not only in hospitals. Some nursing homes are real problems.
