Clinical picture
This section has been translated automatically.

In immunocompetent people, skin infections are rarely observed. In most cases it is colonization of ulcers or burns. The nails are rarely affected(onychomycosis).

Fusariosis in immunocompetent persons: Deeply localized or disseminated granulomatous skin infections are usually only found in immunocompromised persons. Infections through non-sterile catheters have also been observed in cases of lack of hygiene in hospitals.

Fusarium solani causes so-called mycotoxicoses, i.e. symptoms of poisoning by mycotoxins (e.g. naphthoquinone, fusaric acid, diacetoxyscirpenol), especially in horses and cattle through the ingestion of mouldy feedstuffs such as hay, silage and cereals, like other species of chimpanzee fungus.

Note(s)

Since the spores of Fusarium species are formed in slimy aggregates called sporodochia, the spores often attach themselves to animals and are spread with them. In contrast to many other moulds, Fusarium species are therefore not adapted to airborne distribution. The spores show hardly any coloration as UV protection.
