    After completing this lab, the student will be able to perform the following objectives:

    DISCUSSION

    1. Define the following: hypha, mycelium, vegetative mycelium, and aerial mycelium.

    2. Describe the principle way molds reproduce asexually.

    3. State the main criteria used in identifying molds.

    1. Describe conidiospores and sporangiospores and name a mold that produces each of these.

    2. Recognize the following genera of molds when given an SDA plate culture and a dissecting microscope and state the type of asexual spore seen:

    a. Penicillium

    b. Aspergillus

    c. Rhizopus

    3. Recognize the following genera of molds when observing a prepared slide under high magnification and state the type of asexual spore seen:

    a. Penicillium

    b. Aspergillus

    c. Rhizopus

    4. Recognize Rhizopus zygospores.

    1. Define dermatophyte and list three common genera of dermatophytes.

    2. Name four dermatophytic infections and state how they are contracted by humans.

    3. Describe macroconidia and microconidia.

    4. Describe how the following may be used to identify dermatophytes: potassium hydroxide preparations of tissue scrapings, DTM, and SDA.

    5. Recognize a mold as a dermatophyte and state how you can tell when given the following:

    a. a flask of DTM showing alkaline products

    b. an SDA culture (under a microscope) or picture showing macroconidia.

    6. Recognize macroconidia and microconidia.

    C. DIMORPHIC FUNGI

    1. Define dimorphic fungi and state how humans usually contract them.

    2. Name three common dimorphic fungal infections found in the United States, state how they are transmitted to humans, and indicate where they are found geographically.

    3. Describe the mold form and the yeast-like form of the following:

    a. Coccidioides immitis

    b. Histoplasma capsulatum

    c. Blastomyces dermatitidis

    4. Recognize Coccidioides immitis and its arthrospores when given a prepared slide and a microscope.
