Trichoderma Spores & Hyphae
Trichoderma spp  are fungi that are present in nearly all soils and other diverse habitats.  They are easily cultured and produce a variety of metabolites that are used commercially and to control the growth of both bacteria and fungi.  For examples, T. reesei has the capacity to produce large quantities of cellulitic enzymes (cellulases and hemicellulases) that are used commercially.  On the other hand, T. viridae produces macrocyclic trichothecenes (trichodermin, trichodermol and verrucarol).  Other potential toxins include gliotoxin and peptaibols (Trichtoxin A).  In addition Trichoderma sp are opportunistic pathogens in immune compromised individuals.

Tang et al 2003; Hou et al, 1972; Munoz et al, 1997;

Furukawa et al, 1998; Anitha & Murugesan, 2005.

In conclusion:  Trichoderma spp add to the antigens and toxins in moisture damaged structures.
