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 ...   

Staphylococcus aureus


An aerobic gram-positive coccus that produces smooth colonies. Pigmentation of the colonies may range from gray, gray-white, yellow, yellow-orange or orange. It produces both free and bound coagulases and hemolysins (exotoxins). Some isolates produce an epidermolytic toxin that is responsible for the staphylococcal scalded skin syndrome. Some isolates produce endotoxins which when ingested are responsible for staphylococcal food poisoning. It can be part of the normal flora of the skin, skin glands, anterior nares, mucous membranes, gastrointestinal tract, and genital tract of humans, warm-blooded animals, and birds. It is an opportunistic pathogen causing a wide range of infections including: furuncles (boils), carbuncles, impetigo, epidermal necrolysis, osteomyelitis, meningitis, endocarditis, pneumonia, mastitis, bacteremia, enterocolitis, staphylococcal food poisoning and toxic shock syndrome.
