Definition
This section has been translated automatically.

Systemic mycoses, which can be caused by various dimorphic fungi (fungi that grow in their parasitic form as yeasts, in their saprophytic form as filamentous fungi) and can lead to primary lung and later to disseminated infestation via inhalation of spores (conidia).

Pathogen
This section has been translated automatically.

The pathogens of these system mycoses are earthlings that are endemic to certain regions of the earth. No transmission from person to person.

The best known representative is the dimorphic fungus Blastomyces dermatitides, pathogen of the North American blastomycosis.

This can be distinguished from the so-called South American blastomycosis, the paracoccidioidomycosis.

Classification

Blastomycoses are counted among the blastomycoses:
  • Blastomycosis of the type Jorge-Lobo: pathogen: Paracoccidioides loboi.
  • Blastomycosis, North American: pathogen: Blastomyces dermatitidis (called Ajellomyces dermatitidis in the sexual stage), a dimorphic fungus which can grow as a yeast and mould. Infection by inhalation of spores present in the soil.
  • Blastomycosis, South American: pathogen: Paracoccidioides brasiliensis (= Blastomyces brasiliensis), a dimorphic fungus which probably lives in the soil and on plants.
