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.
