Species/Subspecies: Blastomyces dermatitidis
Categories: Animal pathogen; human pathogen
Etymology: Genus name: germ fungus.
Species epithet: of skin.
Alternative Species Name(s):Ajellomyces dermatitidis är namnet på teleomorfen av denna svamp och bör alltså inte användas.
Significance:This fungus is of minor importance in Sweden, but occurs in eastern North America and sporadically in India and the Middle East.

Macromorphology (smell):
Micromorphology: Like mould: Oval or pear-shaped conidia (2-10 µm in diameter) are formed on conidiophores or directly on septated hyphae.
Like yeast: The yeast cells are thick-walled and 8-10 µm in diameter.
Reproduction:
Spec. Char.: This is a thermally dimorhic fungus.
Reservoir: Moist and acid soil, which is enriched with organic matter.
Disease/effect:
Virulence Factors: BAD 1 (Blastomyces adhesin 1), which is a surface protein that promotes adhesion to cells in the respiratory system and modulates the immune system of the host animal.
Diagnostics: There are PCR systems for detection and identification of B. dermatitidis.
