Thank you CharonY! Greatly appreciate the info. I understand that much of these are harmless, which is reassuring, however, there is one substance among the bunch which is very irritating, and makes a burning sensation on the skin. Have you heard of anything like that?

Hello Folks. I am a non-scientist with a few scientific questions, which I'm submitting here in hopes of an answer or two from you, the experts. I have purchased some used property through a normal, straight-forward business transaction, through a seemingly reliable source. As it turned out, this location was contaminated with something that, when damp, has made me ill, and when dry, has become very irritating when breathing, and on the skin. I normally wouldn't post on this, but it has been an ongoing situation for some months now and has been difficult to mitigate. I have tried bleach (didn't work), 35% H2O2 (worked but corrosive/toxic), 91% alcohol (works, but flammable) and planning to use activated chlorine dioxide. I almost went broke paying for some environmental tests, the results of which follow: 1). Kocuria kristinae (high count) 2). Micrococcus sp. (med. count) 3). Staphlococcus sp. not aureus (lower count) 4). Bacillus species (lower count) 5). Corynebacterium sp. (lower count) 6). Rhizobium sp. (lower count) My questions, if you would be so kind, are as follows: a) Can you tell me which is the very irritating, and ill-making strain? b) Is it dangerous short term/long term? c) Where does it come from or originate? d) Best option for complete mitigation. I have never experienced this type of thing before, and I'd just like to find out a little more about it. Any and all info would be very greatly appreciated! Thank you in advance!
