Re: Trichothecene producing molds that grow under low humidity?

[Guest guest]

There are alot more molds than that, that produce trichothecenes but I can't

spell them all. LoL!!!!

Stachy requires a lot of water for a prolonged time, so it's out of

the question. Other molds that produce trichothecenes are Fusarium,

Trichoderma, Trichothecium, Myrothecium, Cephalosporium,

Cyclindrocarpen, Verticimonosporium and Calonectria.

For instance I have had papers, and wooden furniture that got

cross-contaminated with this mold (whose identity I'm still not sure

about) under completely normal humidity levels - no excessive

humidity. There has never been visible mold growth though, but I can

sense its presence easily. Sometimes borax can significantly alleviate

the problem. Sometimes I must apply H2O2 to deal with mycotoxins.

Since borax does have effect on this mold, and it is not known to

decompose mycotoxins, it follows that this mold is still alive. So

what can it be?

These species are mentioned in the scientific literature as the most

important ones. There are of course many species (or subspecies?) of

each of them. I think Fusarium has about 40 strains, each with

different toxins.

Ok, which of the mold species are likely to be alive and even produce

trichothecenes under normal humidity levels (without any prior

floodings/water intrusions etc.) on materials such as wood?

Hummm, lets see-2 things I can think of-one, the spores do not have

to be viable to produce a reaction-I know we speak dead or alive- but

viable-or not viable is more accurate- a non viable spore (non-

reproducable) is still a major health problem for us-the coatings

(biofilms) are highly reactive-and hard to break down. The second

thing is mycotoxins vary so much in their suseptibility to cleaning

products that it could be cross contaminated soley with toxin, but of

a kind that cleaned up easily with borax. Hopefully the future will

be a wonderfull place- where we will all be able to own a hand held

spore and toxin sensor-that instantly analysis the type of toxin and

the recommended clean up-or just flashes-warning!!! toxin levels too

high!!!leave area immediatly!! LOL

heres one that hasn't been talked about much, chaetomium, I was

exposed to this one and fell like it played it's role in my illness.

I read that it is uaually where stachy is and it can produce

mycotoxins but not sure all what kinds. haven't got around to

researching it much but here's some interesting info. on it.

Well, borax is good for people with the toxic mold problem because it

both kills and inhibits further mold growth. It penetrates wood better

than anything else (certainly better than bleach). I'm pretty sure

borax is not known to have any effect on mycotoxins or dead mold spores.

The same holds true for quaternary ammonium salts. They only kill

mold, but don't inactivate dead mold or mycotoxins.

Personally I think some strains of Fusarium are the most likely

candidates... or possibly Trichoderma or Trichothecium. I think

Chaetomium requires a lot of water like Stachy so it's probably not that.

Anybody know some lab that would do extensive mold testing (down to

individual species) taken from a sample that has no visible mold growth?

Oh , that's distant future! I don't think we'll live to see that.

Most people stare blankly at me as soon as I start speaking about

toxic mold and mycotoxins. They have no idea how happy they should be!
