Fungal infections can affect almost all organs and systems of the body. The detection of mycelial (mold) fungi in humans is a sign of a pathological process. The carriage of mold fungi in the human body is not possible.

The main representatives of mold fungi that can cause disease include the genera Penicillium, Aspergillus, Fusarium. These fungi can cause mycoses (fungal infections) and mycotoxicoses (poisoning with fungal waste products).
