Mold allergies are present in a minority of the population that is genetically predisposed to mold, and usually this allergy is not life threatening. Black molds, or so called toxic molds, can ...
Most dermatophyte fungi take the form of mold, as opposed to a yeast, with an appearance (when cultured) that is similar to other molds. Opportunistic infection by molds [33] such as Talaromyces marneffei and Aspergillus fumigatus is a common cause of illness and death among immunocompromised people, including people with AIDS or asthma. [34] [35]
Aflatoxin B 1 is considered the most toxic and is produced by both Aspergillus flavus and Aspergillus parasiticus. Aflatoxin M 1 is present in the fermentation broth of Aspergillus parasiticus, but it and aflatoxin M 2 are also produced when an infected liver metabolizes aflatoxin B 1 and B 2.
Aflatoxin B 1, the most toxic, is a potent carcinogen and has been directly correlated to adverse health effects, such as liver cancer, in many animal species. [11] Aflatoxins are largely associated with commodities produced in the tropics and subtropics , such as cotton , peanuts , spices , pistachios , and maize .
Spores need three things to grow into mold: nutrients – cellulose (the cell wall of green plants) is a common food for indoor spores; moisture – to begin the decaying process caused by mold; and time – mold growth begins from 24 hours to 10 days after the provision of growing conditions.
Over time mold species that thrive in indoor conditions free from the usual outdoor stresses of UV, rain, wind, etc. began to have enough extra energy to evolve toxic coatings for their spores, to provide protection for them from being consumed by microbes, insects etc. at the near-microscopic level. Mold spores are about one micron in diameter.
Stachybotrys chartarum (/ s t æ k iː ˈ b ɒ t r ɪ s tʃ ɑː r ˈ t ɛər ə m /, stak-ee-BO-tris char-TARE-əm), [2] also known as black mold [3] is a species of microfungus that produces its conidia in slime heads. Because of misinformation, S. chartarum has been inappropriately referred to as toxic mold.
U.S. Army Public Health Center Toxicology Lab technician assessing samples. Toxicology testing, also known as safety assessment, or toxicity testing, is the process of determining the degree to which a substance of interest negatively impacts the normal biological functions of an organism, given a certain exposure duration, route of exposure, and substance concentration.
