[...] Moisture is one of the key requirements for mold growth in homes. There are different types of mold. Some molds require relatively very low levels of available moisture for them to grow. These types of mold are referred to as xerophilic and are likely to be found in almost every home. The common xerophilic fungi belong to the genera AspergillusAspergillus spp are reported to be allergenic. Members of this genus are reported to cause ear infections (see Aspergillus niger) . Many species produce mycotoxins (see Aspergillus flavus) which may be associated with disease in humans and other animals . Toxin production is dependent on the species or a strain within a species and on the food source for the fungus. Some of these toxins have been found to be carcinogenic in animal species. Several toxins are considered potential human carcinogens. Common cause of extrinsic asthma (immediate-type hypersensitivity: type I)., PenicilliumA large number of organisms have have been placed in this genus. Identification to species is difficult. Often found in aerosol samples. Penicillium is commonly found in soil, food, cellulose and grains. It is also found in paint and compost piles. It may cause hypersensitivity pneumonitisInflammation of the lungs., allergicCaused by or relating to an allergyA damaging immune response by the body to a substance, esp. pollen, mold spores, fur, a particular food, or dust, to which it has become hypersensitive. or having an allergyA damaging immune response by the body to a substance, esp. pollen, mold spores, fur, a particular food, or dust, to which it has become hypersensitive. to (a substance). alveolitis in susceptible individuals. It is reported to be allergenic. It is commonly found in carpet, wall paper, and in interior fiberglass duct insulation. Some species can produce mycotoxinsToxic substances produced by fungi.. Common cause of extrinsic asthmaNarrowing of the bronchial tubes, where the muscles go into spasm and the patient has difficulty breathing. (immediate-type hypersensitivity: type I). Acute symptoms include edema and bronchiospasms, chronic cases may develop pulmonary emphysema. and WallemiaWallemia sp. is found in sugary foods, salted meats, dairy products, textiles, soil, hay and fruits.. Some other molds require wet or highly damp prolonged conditions. These are referred to as hydrophilic (“water loving”) fungi and their presence in homes is an indication of moisture damage. Examples of indicators of moisture damage include Chaetomium, StachybotrysStachybotrys sp. may produce a trichothecene mycotoxin- Satratoxin H – which is a poisonous by inhalation. The toxins are present on the fungal spores. Stachybotrys sp. grows on building material with high cellulose content and low nitrogen content. Stachybotrys sp. is rarely found in outdoor samples. It is usually difficult to find in indoor air samples unless it is physically disturbed or if it dries out and become airborne. There is controversy about toxigenic effects through inhalation of spores or mycelia. and FusariumFusarium sp. are found on a wide range of plants and in humidifiers. Several species in this…. [...]

[...] Often, people will ask the laboratory if it tests for toxic mold. The lab can test and identify any mold. If a mold is known to produce toxins (mycotoxinsMycotoxins are toxic byproducts (seconday metabolites) produced by fungi.) the lab can provide this information. It is good to remember toxigenic molds (what the public refers to as toxic mold) do not produce the toxins all the time. Therefore, presence of a toxigenic mold in a house does not necessarily mean the occupants were exposed to mycotoxinsMycotoxins are toxic byproducts (seconday metabolites) produced by fungi.. However, some of the toxic molds are also capable of causing mold allergy. Learn more on toxic mold in the article “MycotoxinsMycotoxins are toxic byproducts (seconday metabolites) produced by fungi.

What Are the Early Signs of Mould Growth? — Thu, 31 Jan 2013 15:45:49 +0000

[...] Musty or earthy odour could suggest there was some hidden microbial growth behind and underneath surfaces, such as carpets, wallpaper, cabinets, and walls. Visible mould growth may appear hairy or as slimy coloured patches that increase in size as the mould grows. It is difficult to tell the type of mould growing on a surface on the basis of colour. It is erroneously thought that visible black mould growth is Stachybotrys. There are many other indoor moulds that appear black or grey. The best way to know the type of mould growing indoors is to send a sample to a reputable laboratory for testing.
