12,13-Epoxy-delta 9-trichothecenes as the probable mycotoxins responsible for stachybotryotoxicosis
Abstract:
Stachybotrys atra cultures grown on oats produced five compounds toxic to brine shrimp; three are the sesquiterpenoid mycotoxins known as 12,13-epoxy-Delta(9)-trichothecenes. One trichothecene is roridin E, a known metabolite of Myrothecium verrucaria. The other two were hydrolyzed to verrucarol, the product of roridin and verrucarin hydrolysis. Spectroscopic data indicate that the two remaining compounds are also 12,13-epoxy-Delta(9)-trichothecenes. These metabolites are probably among those responsible for stachybotryotoxicosis.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
