Macrocyclic trichothecene toxins produced by Stachybotrys atra strains isolated in Middle Europe.
A total of 17 strains of Stachybotrys atra isolated in Hungary and Czechoslovakia were cultured on Sabouraud agar, and the toxins produced by them were chemically analyzed by gas-liquid chromatography, high-pressure liquid chromatography, and mass spectroscopy. Furthermore, brine shrimp (Artemia salina) bioassay was used for the determination of toxicity of the compounds examined. Macrocyclic t...
متن کاملMacrocyclic trichothecene toxins produced by a strain of Stachybotrys atra from Hungary.
A strain of Stachybotrys atra isolated from a field case of stachybotryotoxicosis in Hungary was cultured in Hungary. All of the compounds toxic to brine shrimp were separated from the culture extract by solvent partition, column chromatography, and preparative thin-layer chromatography. Two of the toxic compounds were identified as verrucarin J and satratoxin H by comparison with pure standard...
متن کاملDetection of airborne Stachybotrys chartarum macrocyclic trichothecene mycotoxins in the indoor environment.
The existence of airborne mycotoxins in mold-contaminated buildings has long been hypothesized to be a potential occupant health risk. However, little work has been done to demonstrate the presence of these compounds in such environments. The presence of airborne macrocyclic trichothecene mycotoxins in indoor environments with known Stachybotrys chartarum contamination was therefore investigate...
متن کاملDetection of airborne Stachybotrys chartarum macrocyclic trichothecene mycotoxins on particulates smaller than conidia.
Highly respirable particles (diameter, <1 microm) constitute the majority of particulate matter found in indoor air. It is hypothesized that these particles serve as carriers for toxic compounds, specifically the compounds produced by molds in water-damaged buildings. The presence of airborne Stachybotrys chartarum trichothecene mycotoxins on particles smaller than conidia (e.g., fungal fragmen...
متن کاملDetection of polar and macrocyclic trichothecene mycotoxins from indoor environments.
A method is described for the qualitative and semi-quantitative simultaneous determination of both non-macrocyclic and macrocyclic trichothecene biotoxins from samples derived from indoor environments. The method includes extraction, sample pre-treatment and reversed-phase HPLC separation followed by tandem mass spectrometric identification and quantification using electrospray ionization on a ...
