Cladosporium is considered to be the most prevalent indoor mold in the world. This strand contains about 60 or so species. Cladosporium spores appear to look like branches or chains. They are easily airborne and can travel long distance. It can grow in a large range of temperatures; this mold species can also colonize in cooler areas as well if the conditions are favorable.
Cladosporium can be found in the normal areas of your home or office, such as attics, bathrooms, crawlspaces, tile, grout, drywall, wallpaper, floor covering etc, but also in the following areas:
*Cladosporium is somewhat unique as it can also settle and begin to colonize on metal surfaces including electrical outlets, air handler units, metal window frames, etc if the conditions are suitable for growth. We commonly find that surface sampling confirms Cladosporium colonies in air handlers, return vents, and duct work where normal organic building dust and debris accumulate along with condensation, or where external air duct leaks occurred into rooftop mounted ducts or where ground duct work was exposed to flooding, such as underneath mobile/modular homes. These instances create the prefect environment for the Cladosporium species to grow. Remember, unlike other mold species that thrive in humid, moist conditions, Cladosporium can grow in cooler areas as well, all it needs is damp or wet material.
Although Cladosporium is not classified as what some call "toxic mold" because it does not produce mycotoxin's, it still carries the potential to cause significant health issues. The species is well known for **triggering asthmatic attacks, allergic rhinitis, and upper respiratory infections secondary to allergies. ***For those with an overly-sensitive immune system they could experience immediate symptoms upon inhaling the Cladosporium spore such as:
*Species C.Corrionii of the Cladosporium family has been known to be pathogenic in humans, causing skin lesions.
Common Worldwide Mold. Higher spore counts in Summer.
Wind-dispersed and a very common indoor mold.
Outdoors decaying plant life, Indoors dust, wallpaper, fabrics, wallboard, chipboard, anywhere moisture is present.
No, but it can produce VOC's (Volatile Organic Compounds) associated with odours.
