Mildew. Low pathogenetic importance and low contactability in humans. Common in immunocompromised and HIV-infected people. Cultivation: Best from subungual detritus of infected nails. Optimum growth temperature: 24-30 °C.

Globally, ubiquitously occurring, e.g. in soil, wood, straw, cereals, fruits (including soya, peanuts, nuts), manure, paper, meat, dairy products (cheese, milk, butter).

ManifestationThis section has been translated automatically.

S.u. Tinea unguium. Infestation of the nail beds of the feet after small traumas, preferably on the big toe. Rarely also infestation of the fingers. Mostly occurring in connection with mycotically changed, yellow-striped nails without previous interdigital mycosis. In chronic cases the mycelium penetrates into the cavities of the nails and spreads like a fern leaf.

  • Long septated hyphae, conidiophores (annellophores).
  • Conidia: Bulky, uniform, size: 5-10 μm Ø, pearl necklace shape with rough, spiky outer walls ("morning star"), usually standing at right angles to the hyphae.
