Fungi have appeared, too, from time to time, in literature and art. Fungi create harm by spoiling food, destroying timber, and by causing diseases of crops, livestock, and humans. Fungi, mainly moulds like Penicillium and Aspergillus, spoil many stored foods. Fungi cause the majority of plant diseases, which in turn cause serious economic losses.
Pathogenic fungi are fungi that cause disease in humans or other organisms. Although fungi are eukaryotic , many pathogenic fungi are microorganisms . [ 1 ] Approximately 300 fungi are known to be pathogenic to humans; [ 2 ] their study is called " medical mycology ".
Fungi are everywhere, but only some cause disease. [13] Fungal infection occurs after spores are either breathed in, come into contact with skin or enter the body through the skin such as via a cut, wound or injection. [3] It is more likely to occur in people with a weak immune system. [14]
Entomopathogenic fungi all typically disperse through the environment through the use of microscopic spores (usually asexual or Conidia) that commonly use hydrophobins and adhesins to attach to and recognize the host cuticle. [4] Germination is environmentally triggered under specific temperature and humidity conditions.
Effects on the host include reduced longevity, fertility, weight, and general vigor. Vertical transmission of microsporidia is frequently reported. In the case of insect hosts, vertical transmission often occurs as transovarial transmission, where the microsporidian parasites pass from the ovaries of the female host into eggs and eventually ...
Scratching also damages skin layers, making it easier for the fungi to spread at the site of the infection. If the fungi and infested debris are not washed from the fingers and fingernails soon enough, the fungi can also infect the skin of the fingers (tinea manuum), and burrow underneath and into the material of the fingernails (tinea unguium ...

Where conditions are right, fungi proliferate into colonies and mycotoxin levels become high. The reason for the production of mycotoxins is not yet known; they are not necessary for the growth or the development of the fungi. [9] Because mycotoxins weaken the receiving host, they may improve the environment for further fungal proliferation.
