Blastomyces dermatitidis

Blas·to·my·ces der·ma·tit·i·dis

(blas'tō-mī'sēz der'mă-tit'i-dis),

A dimorphic soil fungus that causes blastomycosis. It grows in mammalian tissues as budding cells and in culture as a white to buff-colored filamentous fungus bearing spheric or ovoid conidia on terminal or lateral short, slender conidiophores. In its perfect (teleomorph) state it is known as Ajellomyces dermatitidis.

Blastomyces dermatitidis

The only species included in the genus Blastomyces. The sexual state (teleomorph) of B dermatitidis belongs to the family Onygenaceae and is termed Ajellomyces dermatitidis, which produces ascospores (sexual spores). B dermatitidis causes two clinical forms of disease (blastomycosis): cutaneous and systemic (disseminated) blastomycosis.

Blas·to·my·ces der·ma·tit·i·dis

(blas'tō-mī'sēz dĕr'mă-tit'i-dis)

A dimorphic soil fungus that causes blastomycosis. It grows in mammalian tissues as budding cells, with a broad junction between mother and daughter cells (thus "broad-based buds") and in culture as a white or buff filamentous fungus bearing spheric or ovoid conidia.
