Indoor MoldsHave you ever wondered what molds can be found in your home, apartment, workplace, or indoors in general? Indoor molds are simply molds that are commonly found indoors. Indoor molds need constant a moisture and nutrient source usually from building materials to grow. It is normal for mold spores to found indoors as well as outdoors. Indoor molds can be found growing in damp places such as under the kitchen cabinet, window seals, basement, etc. Three most common indoor molds are: Aspergillus, Penicillium, and Cladosporium.
Aspergillus is a really common mold spore that is found everywhere. In homes, Aspergillus can be seen growing on damp walls. There are hundreds of species of Aspergillus known to man and out of those hundreds, possibly two are known to produce toxins that are possibly harmful to human beings. It is rare that Aspergillus is seen as a potential threat or health risk to healthy humans. It may have an effect on people that have a weak immune system possibly due to HIV or AIDS. Aspergillosis is a rare disease where Aspergillus invades and grows in the lung cavities. Being an indoor mold, Aspergillus is the most common indoor spore that can be present in an indoor setting.
Penicillium is another type of indoor mold that is commonly found. Penicillium is often found growing indoors on water damaged materials such as wallpaper, carpet, and plywood. Penicillium can generally be found growing on foodstuffs in homes that have been sitting for an extensive time period. When looking for Penicillium growth on food, it can be observed as a bluish mold growing on possibly fruit, bread, or cheese. Infections may occur in people having HIV or AIDS. In these cases, a human being may be vulnerable to having an infection of the ear, skin, or even the respiratory system. Penicilliosis is a disease usually found in patients who have HIV and also acquired an infection from Penicillium marneffei. All in all, Penicillium doesn’t pose as a risk to the typical healthy individual as an indoor mold.
Cladosporium is also a common indoor mold usually found in households abroad. It can be observed as an olive green, brown, or sometimes even black colony. Cladosporium can be found in household potted plants. Cladosporium can also be found on other indoor resources such as: damp construction materials, paints, wood, and moist insulation inside of cooling systems. As an indoor mold it is more commonly found on floors, mattresses, rugs, and damp or possibly water damaged walls. Cladosporium most times isn’t a harmful mold spore to healthy humans. Although in rare occasions it can be a risk faster to someone with an immunodeficiency. Cladosporium can cause problems for people with asthma. Skin and toenail infections are also health issues that can arise from Cladosporium.
Aspergillus, Penicillium, and Cladosporium are very common mold spores found in indoor settings. These indoor mold spores don’t pose as health issues to normal healthy people and at considerable levels.
