Paracoccidioides brasiliensis causes paracoccidioidomycosis (South American blastomycosis). Its tissue yeast forms the diagnostic "mariner's wheel" of multiple peripheral buds. Mor...
Coccidioides causes Valley fever. In tissue it forms a spherule packed with endospores, not a yeast, and in the environment it makes infectious arthroconidia. Its morphology, why i...
Blastomyces dermatitidis appears in tissue as a broad-based budding yeast with a thick, double-contoured cell wall (not a capsule). Learn its morphology, dimorphism, pathogenesis,...
Histoplasma capsulatum is a dimorphic fungus identified by its tuberculate macroconidia and by small intracellular yeast in macrophages. Learn its morphology, why the name is a mis...
Sporothrix schenckii causes sporotrichosis (rose gardener's disease), appearing as cigar-shaped yeast in tissue and rosette conidia in the mold form. Learn its morphology, lymphocu...
Dimorphic fungi grow as mold in the environment and yeast in the body. See the six classic examples compared, why the 37°C switch is a virulence factor, their tissue forms, geograp...
