Under The Scope
www.pureaircontrols.com/labserv.htm
by Dr. Rajiv Sahay, Pure Air
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...
Fusarium
species
A rapidly-growing fungus that produces a pale or bright colored colony within four days, when incubated at 25
O
C (77
O
F). It is found worldwide and is commonly isolated from plants, soil, caves, salt marshes, mangrove mud, insects, gerbils, bird feathers, water, wooden furniture, and wood pulp.
Clinical Relevance:
Fusarium sp
.: Some isolates produce the mycotoxin trichothecene which can cause disease in humans and animals. Trichothecene targets the circulatory, alimentary, skin, and nervous systems. Some isolates produce the mycotoxin vomitoxin on grains which produce disease by either ingestion or inhalation of the contaminated grains. It can be an opportunistic human pathogen causing allergic disease, eye, skin, and nail infections.
Fusarium sp.
