The following organisms have been shown to have adverse effects to human health. Chartarum Toxic fungus that inhabits wet cellulose containing material, such as gypsum board. Stachybotras contains a toxin that is detrimental to human health, that may be present even after the organism has died. Aspergillis Prolific fungus that grows in a wide temperature range.
Inhalation causes opportunistic infections in immune deficient people.
Can be a serious problem in health care facilities. Today's indoor climate control systems are complex machines requiring a great deal of monitoring and maintenance. When left unserviced HVAC systems generate condensate which results in standing water. When this water is left in contact with cellulose components it fosters an ideal breeding ground for molds, funguses, and pathogenic bacteria. Increasing evidence is pointing towards the critical relationship between these microorganisms and human health.
