It can grow on various other high-cellulose substrates and needs a certain amount of moisture to develop. Alternaria molds require water activity values above 0. Indoors, Alternaria can be found in carpets, wallpaper, textiles, window frames, and air conditioning systems. However, Alternaria spores identified indoors often originate from the outdoor environment. There are two common species of Alternaria mold: Alternaria alternata and Alternaria tenuissima.
These molds can commonly be found outdoors and found in buildings like an apartment or house. The mold can grow from spring all through to summer.
The mold can grow among other species of mold like Stachybotrys , Phoma , and Fusarium. Because it is so common in summer and spring, Alternaria is thought of as a common allergen. Common habitats of Alternaria molds include plants, grass, trees, and soil.
It is mostly found in areas with temperate climates. In dry seasons and when it is hot and windy, many spores are spread in the air. Indoor molds are caused by spores that manage to enter buildings. Like any mold species, it is unsurprising that this mold thrives in humid, damp, and dark environments. They commonly grow on food and wood, apart from the Alternaria alternate, which can also colonize tiles, bricks, wallpapers, canvas, and iron. The most vulnerable people to these molds are those with pulmonary diseases, asthma, allergies, or even those who have a weak immune system.
Alternaria has been associated with the onset of asthma in children [4,5]. Also, high levels of Alternaria contamination in cereal grain have been linked to oesophageal cancer in China [6]. When one is exposed to mold for prolonged periods, it can cause several health issues, especially in the elderly, children, and babies.
Once you notice any of these symptoms, especially during the summer and spring seasons, you should check for molds because there is a high chance that they are the cause. Many species of Alternaria have been known to cause health problems in humans. They produce mycotoxins that affect the respiratory system, skin, and nails.
Other species are common allergens that may lead to asthma and hay fever, but they rarely cause serious infections in healthy adults. They are of particular risk to immuno-suppressed and wounded individuals. Aspergillus is a common fungus whose spores are present in the air we breathe yup, you may be breathing it in right at this very moment.
Indoors, Aspergillus will grow on surfaces such as building materials, leather, and even clothing, depending on the amount of moisture present. They can be commonly found in basements and cellars. Other molds can also piggyback on it, causing serious health effects to both allergy sufferers and non-sufferers alike.
In fact, people with compromised immune systems can be in danger of contracting Aspergillosis, a group of diseases that includes fungal sinusitis, nail fungus and keratitis eye infection. How should you avoid them? Because they are so common, it is actually difficult to avoid them completely according to the CDC.
But for those allergic to Aspergillus, they are most commonly present when cleaning is being carried out mechanically e. Simply stepping out of the vicinity when a room is being cleaned can avoid allergic reactions and triggers for those sensitive to Aspergillus. For those with numerous indoor plants and flower pots, consider relocating them or replacing them as various Aspergillus species are commonly found in indoor plant soils. Penicillium can actually be identified by those who have experienced its heavy musty odor.
They are commonly found on building materials, fabrics, and particularly when food spoils as they are the most common fungi causing food spoilage. Remember that green mold often seen on oranges? In air conditioning systems, Penicillium can often be detected on cooling coils and or the interior fiberglass liner. While Penicillium is best known as the mold type that gave birth to the first of the antibiotics, penicillin, some species of this mold type are known to cause a number of specific allergies including asthma and hay fever.
Cladosporium is yet another common mold types found worldwide. Peak production is around 2 pm. Primarily outdoors with counts being high during mild weather months. It grows on organic debris in the soil. Increases during wet, rainy weather and requires splashing for their dispersal. A prominent organism that loves dead leaves and plants. Thrives in grouting in shower stalls pink mold.
It is found in soil and is responsible for spoilage of chemicals, water, aircraft fuel, fruits, and vegetables. Being enemy of both plant and man, it is the F in VFN-resistant tomato plants. It is important in the Midwest and the South, as it grows on farm crops, tomatoes, and grains. If brown spots appear in your lawn in the late summer, it could be this mold. It peaks in ragweed seasons. Grows on ornamental flowers peonies, lilacs, etc. It is the gray mold on grapes.
It is harmful to potato crops during very wet growing seasons. It is important in the Midwest as it grows on farm crops, grains, grasses, and flour. Its spores are easily dispersed in the air by lawn mowing. Some species develop on many plant parts such as ferns, gladioli, barley, and grass lawns. Found outdoors. Known as red bread mold because of its prevalence in bakeries and flour mills.
Found everywhere in the outdoors. Counts increase after it rains and when it is foggy. Not a lot known about this mold. A downy mildew which causes destruction to grapes, onions, lettuce, beans and grass.
Found especially after a few wet days. Are plant pathogens, grown in large quantities on corn, oat, or wheat.
