  1. What are the general characteristics of fungi? Cell wall? Cell membrane? Use oxygen or not? Where does it get nutrients? Why do we see more fungal infections?
    • A. Eukaryotic cells
    • B. ALL have cell walls - often composed of chitin and glucan.
    • C. Cell membranes has ergosterol instead of cholesterol (as a sterol).
    • D. MOST are aerobes - some are facultative NONE are obligate anaerobe.
    • E. In nature fungi are saprobes - get nutrients from decomposition.
    • F. With more ppl having immunosuppression, we have more fungal opportunistic infections.
  2. What is the role of spores for fungi?
    • Fungi form spores for REPRODUCTION.
    • Many species raise up a fungal head (conidia and other names)
    • THROW spores
  3. Both yeast and mold forms present in fungi. Where does these form exist?
    • A. Yeast are generally the form IN YOU.
    • 1. single cell
    • 2. asexual budding - divide by mitosis (bacteria binary fission)
    • B. Mold - free living form (saprophytic) - multicellular form
    • 1. grow as long filaments called hyphae.
    • 2. cluster of hyphae forms a mat called a mycelium.
    • 3. may have conidia - asexual reproductive elements.
  4. How are fungi diagnosed and give examples?
    • I. Growth/culture
    • A. Sabouraud's agar
    • B. ID/susceptibility testing similar to bacteria
    • II. Microscopy - may digest keratin with KOH
    • A. see much larger eukaryotic cells
    • B. May see hyphae or spores.
    • C. Immunofluorescence
    • III. Antibody/Antigen/Molecular Biology
    • A. ELISA
    • B. PCR
