Basics
Mold allergy sufferers are mostly confronted with invisible enemies. Rarely can the triggers of the allergy be seen with the naked eye, so determining the allergen is relatively complicated. Nevertheless, the allergic reaction can be traced back to the mold if one observes very closely when the reactions occur. This self-observation is an important tool for the doctor to be able to narrow down the search for the allergen.
What actually are molds and which components of the molds trigger an allergic reaction?
Molds are microscopic organisms that consist of numerous cells and are found in large quantities when they occur.
In the case of mould allergens (=allergy-triggering components of the fungi), it is not the fungi themselves that trigger an allergy, it is the spores that are released into the air by the fungi. These spores are released by the mushrooms in and of themselves to reproduce and are spread by the wind. Should an allergy sufferer inhale them, an allergic reaction will occur.
It is precisely these fungal spores that can trigger an allergic reaction in humans. If a person breathes in the allergens of the molds, then it can lead to the reaction. A non-allergic person does not notice anything about the spores they are breathing in. The allergic person reacts as if a pathogen enters the body and the immune system tries to fight this pathogen.
Less commonly, the allergic reaction is due to oral ingestion of the molds. That is, when you eat the pathogens. This can be in the form of moldy cheese but also moldy bread.
