Under The Scope

by Dr. Rajiv R. Sahay, EDLab Manager
Pure Air Control Services and the Environmental Diagnostics Laboratory are pleased to introduce "Under the Scope", a new section of the IEQ REVIEW. There are over 100,000 species of fungi. Many fungi are good and useful (edible mushrooms would be an example of these) while some cause problems (some fungi can injure plants and humans). Every week the IEQ Review will describe a specific microorganism, its morphological origin and potential health effects. If you would like to know about a specific organism and/or would like it published in The IEQ Review please email Dr. Rajiv Sahay with the Environmental Diagnostics Laboratory (EDL) at Pure Air Control Services laboratory@pureaircontrols.com
This week we will cover ...
Aspergillus versicolor Conidia dimensions 2-3.5 microns. It is commonly found in soil, hay. cotton and dairy products. As the name of this fungus implies, the conidia A. versicolor may be of various colors. This species is very common and displays great variability in colony pattern and size.
Clinical Relevance:
A. versicolor can produce a mycotoxin sterigmatocystin and cyclopiaxonic acid. These toxins can cause diarrhea and upset stomach. It is reported to be a kidney and liver carcinogen. This species is only occasionally pathogenic.
