Ecology
- Contaminant
- Commensal
- Colonization
- Infection without damage
- Disease with damage
Clinical Categories
- Yeasts (single-cell)
- Candida
- Cryptococcus
- Molds (multi-cellular)
- Hyalohyphomycosis (hyaline molds)
- Phaeohyphomycosis (dematiaceous or pigmented)
- Mucormycosis
- Dermatophyte (also hyaline)
- Thermally dimorphic fungi (yeast at 37°C, molds below 37°C)
- Histoplasmosis
- Great Lakes region and Ohio River Valley
- Very small cells
- Blastomycosis
- Especially prevalent in Ontario
- Coccidiomycosis
- South-western US (Arizona and Nevada)
- Larger cells
- Histoplasmosis
- Pneumocystis
- Unusual fungi or fungal-like organisms
Identification of Molds
- Macroscopic
- Colony appearance
- Growth rate
- Microscopic
- Hyphae
- Sexual reproduction (rarely)
- Asexual reproduction
- Blastic conidia: conidia created by budding
- Blastoconidia: created by budding from the apex or side of a conidiophore. May be solitary, in chains, sympodial (like alternating leaves), or multiseptate.
- Annelloconidia: with rings on an annellide.
- Phialoconidia: with a collarette on a bottle-shaped phialide, conidia releated from collaratte.
- Thallic conidia: conidia created from existing hyphal segments
- Arthroconidia: may be simple or alternate (with disjunctor cells).
- Aleurioconidia: may have macroconidia or microconidia.
- Chlamydospores
- Blastic conidia: conidia created by budding
Identification of Yeasts
- Macroscopic
- Colony appearance
- Microscopic
- Budding cells: may be unipolar or (rarely) bipolar, or (rarely) division by fission
- Filamentation, including pseudohyphae and true hyphae (which includes germination tubes)
- Conidium or chlamydospore production
- Physiological tests, including chromagar Candida medium
- Molecular tests
Further Reading
- Anaissie Clinical Mycology 2e
