  1. The study of fungi
    mycology
  2. Mycology is the study of __ and is unicelluar
    yeast
  3. __are multicellular and filamentous
    molds
  4. Yeast reproduce by__
    budding
  5. Molds have thread-like filaments called__
    hyphae
  6. Hyphae with cross-walls are
    septate hyphae
  7. Hyphae without cross-walls are
    aseptate or nonseptate hyphae
  8. A mass of hyphae is called
    mycelium
  9. In molds, mycelium that obtain nutrients are called
    vegetative mycelium
  10. Mycelium that produce spores are called
    reprodcutive or aerial mycelium
  11. __are a means of reproduction for molds
    spores
  12. Fragmented or retangular asexual spores
    arthrospores
  13. Asexual budding yeast
    blastospores
  14. Thick wall spores formed by segmentation of hyphae
    chlamdiospores
  15. 3 kinds of chlamdiospores
    treminal(at the end of hyphae), intercalary(within the strand), sessile(on the sides and formed withinn a hyphae)
  16. Asexual spores produced in a chain
    conidiospores(ie. penicilillin)
  17. Form spores at the end of a hyphae
    sporangiospores(ie. rhizopus or black bread mold)
  18. The nuclues of a male passes thru a bridge into a female cell and fusion of the nuclei produces a zygote
    ascospores
  19. The female cell becomes a sac-like structure which contains 2-8 ascospores. the cells divide by meiosis
    Ascus(ie. penicillin)
  20. Sexual spore formed on a pedestal called a basidium which produces the spores
    basidiospores(ie. mushroom caps)
  21. Sexual spores produced when 2 hyphae form an arm called a zygophore
    zygospore or orospores
  22. When zygophore extend and meet each other they fuse and form a thick wall called a
    zygosporangium(ie. rhizopus)
  23. Fungi with 2 forms of growth
    dimorphic fungi
  24. Dimorphic fungi grow as yeast at what temp.
    37 celcius
  25. Dimorphic fungi grow as mold at what temp.
    25 celcius
  26. Imperfect fungi contains the__which infect skin, hair, and nails
    dermatophytes
  27. Dermatophytes produce the disease ringworm called__
    tinea
  28. Ringworm of the nails
    Tinea unguium
  29. Ringworm of the beard
    Tinea barbae
  30. Ringworm of the scalp
    Tinea capitis
  31. __infection has spores outside the harishaft
    ectothrix
  32. __infection has hyphae inside the hairshaft
    endothrix(ie. black dot ringworm)
  33. Ringworm of the body
    Tinea corporis
  34. Ringworm of the groin and anal
    Tinea cruris
  35. (Ringworm) athlete's foot
    Tinea pedis
  36. Discolored areas of the skin
    Tinea vesicolor
  37. A dimorphic fungi found in rose thorns, causes "Rose Fever"
    sporothrix
  38. A dimorphic yeast that can be found on mucous membranes of mouth, throat and vagina
    Candida albicans
  39. Diseases candida can cause
    oral thrush, vulvovaginitis, cutaneous, nails, lungs, urinary, intestinal, and systemic
  40. Cryptococcus infects
    lung, brain, and bone
  41. Cryptococcus is found in soil and from
    pigeon droppings
  42. A lesion occurs in the lungs, heals and calicifies, similar to T.B.
    Histoplasma
  43. Causes a "fungi ball" in the lungs
    Aspergillus
  44. Produces alfatoxins in food that can be carcinogenic to the liver
    Aspergillus flavus
  45. Causes Malts Workers Disease. Found in soil and manure, causing allergic reactions
    Aspergillus fumigatus
  46. Mycosis infects the outer layer of skin, hair, and nails
    superficial
  47. Mycosis destroys the keratin of skin, hair, and nails
    cutaneous
  48. Mycosis infects skin, muscle, and connective tissue
    subcutaneous
  49. Mycosis infects deep tissue and organs usually fatel
    systemic
  50. Fungi that spreads through the body is said to
    disseminates
  51. Protozoans are__cells
    eucaryotic
  52. Protozoans are classified on basis of
    mobility
  53. Protozoans have__cell structures
    complex
  54. Helminths are
    worms
  55. Consist of fluke and tapeworms
    flatworms
  56. Harbors the adult stage
    definitive host
